+.SH NAME
+free \- Display amount of free and used memory in the system
+.SH SYNOPSIS
+.B free
+.RI [ options ]
+.SH DESCRIPTION
+.B free
+displays the total amount of free and used physical and swap memory in the
+system, as well as the buffers and caches used by the kernel. The
+information is gathered by parsing /proc/meminfo. The displayed
+columns are:
+.TP
+\fBtotal\fR
+Total usable memory (MemTotal and SwapTotal in /proc/meminfo). This includes
+the physical and swap memory minus a few reserved bits and kernel binary code.
+.TP
+\fBused\fR
+Used or unavailable memory (calculated as \fBtotal\fR - \fBavailable\fR)
+.TP
+\fBfree\fR
+Unused memory (MemFree and SwapFree in /proc/meminfo)
+.TP
+\fBshared\fR
+Memory used (mostly) by tmpfs (Shmem in /proc/meminfo)
+.TP
+\fBbuffers\fR
+Memory used by kernel buffers (Buffers in /proc/meminfo)
+.TP
+\fBcache\fR
+Memory used by the page cache and slabs (Cached and SReclaimable in /proc/meminfo)
+.TP
+\fBbuff/cache\fR
+Sum of \fBbuffers\fR and \fBcache\fR
+.TP
+\fBavailable\fR
+Estimation of how much memory is available for starting
+new applications, without swapping. Unlike the data
+provided by the \fBcache\fR or \fBfree\fR fields,
+this field takes into account page cache and also that
+not all reclaimable memory slabs will be reclaimed
+due to items being in use (MemAvailable in /proc/meminfo, available on
+kernels 3.14, emulated on kernels 2.6.27+, otherwise the same as \fBfree\fR)

+.TH KILL 1 "2023-01-16" "procps-ng" "User Commands"
+.SH NAME
+kill \- send a signal to a process
+.SH SYNOPSIS
+.B kill
+[options] <pid> [...]
+.SH DESCRIPTION
+The default signal for kill is TERM.  Use
+.B \-l
+or
+.B \-L
+to list available signals.  Particularly useful signals include HUP,
+INT, KILL, STOP, CONT, and 0.  Alternate signals may be specified in
+three ways:
+.BR \-9 ", " \-SIGKILL
+or
+.BR \-KILL .
+Negative PID values may be used to choose whole process groups; see
+the PGID column in ps command output.  A PID of
+.B \-1
+is special; it indicates all processes except the kill process itself
+and init.
+.SH OPTIONS
+.TP
+.B <pid> [...]
+Send signal to every <pid> listed.
+.TP
+.B \-<signal>
+.TQ
+.B \-s <signal>
+.TQ
+.B \-\-signal <signal>
+Specify the
+.B signal
+to be sent.  The signal can be specified by using name or number.
+The behavior of signals is explained in
+.BR signal (7)
+manual page.
+.TP
+\fB\-q\fR, \fB\-\-queue \fIvalue\fP
+Use
+.BR sigqueue (3)
+rather than
+.BR kill (2)
+and the value argument is used to specify
+an integer to be sent with the signal. If the receiving process has
+installed a handler for this signal using the SA_SIGINFO flag to
+.BR sigaction (2),
+then it can obtain this data via the si_value field of the
+siginfo_t structure.
+.TP
+\fB\-l\fR, \fB\-\-list\fR [\fIsignal\fR]
+List signal names.  This option has optional argument, which
+will convert signal number to signal name, or other way round.
+.TP
+.BR \-L , \ \-\-table
+List signal names in a nice table.
+.TP
+.PD
+.SH NOTES
+Your shell (command line interpreter) may have a built-in kill
+command.  You may need to run the command described here as /bin/kill
+to solve the conflict.
+.SH EXAMPLES
+.TP
+.B kill \-9 \-1
+Kill all processes you can kill.
+.TP
+.B kill \-l 11
+Translate number 11 into a signal name.
+.TP
+.B kill -L
+List the available signal choices in a nice table.
+.TP
+.B kill 123 543 2341 3453
+Send the default signal, SIGTERM, to all those processes.
+.SH "SEE ALSO"
+.BR kill (2),
+.BR killall (1),
+.BR nice (1),
+.BR pkill (1),
+.BR renice (1),
+.BR signal (7),
+.BR sigqueue (3),
+.BR skill (1)
+.SH STANDARDS
+This command meets appropriate standards. The
+.B \-L
+flag is Linux-specific.
+.SH AUTHOR
+.UR albert@users.sf.net
+Albert Cahalan
+.UE
+wrote kill in 1999 to replace a bsdutils one that was not standards
+compliant.  The util-linux one might also work correctly.

+.TH PGREP "1" "2023-01-16" "procps-ng" "User Commands"
+.SH NAME
+pgrep, pkill, pidwait \- look up, signal, or wait for processes based on name and other attributes
+.SH SYNOPSIS
+.B pgrep
+[options] pattern
+.br
+.B pkill
+[options] pattern
+.br
+.B pidwait
+[options] pattern
+.SH DESCRIPTION
+.B pgrep
+looks through the currently running processes and lists the process IDs which
+match the selection criteria to stdout.  All the criteria have to match.
+For example,
+.IP
+$ pgrep \-u root sshd
+.PP
+will only list the processes called
+.B sshd
+AND owned by
+.BR root .
+On the other hand,
+.IP
+$ pgrep \-u root,daemon
+.PP
+will list the processes owned by
+.B root
+OR
+.BR daemon .
+.PP
+.B pkill
+will send the specified signal (by default
+.BR SIGTERM )
+to each process instead of listing them on stdout.
+.PP
+.B pidwait
+will wait for each process instead of listing them on stdout.
+.SH OPTIONS
+.TP
+\fB\-\fR\fIsignal\fP
+.TQ
+\fB\-\-signal\fR \fIsignal\fR
+Defines the signal to send to each matched process.  Either the numeric or
+the symbolic signal name can be used. In
+.B pgrep
+or
+.B pidwait
+mode only the long option can be used and has no effect unless used in conjunction with
+\fB\-\-require\-handler\fR to filter to processes with a userspace signal
+handler present for a particular signal.
+
+.TP
+\fB\-c\fR, \fB\-\-count\fR
+Suppress normal output; instead print a count of matching processes.  When
+count does not match anything, e.g. returns zero, the command will return
+non-zero value. Note that for pkill and pidwait, the count is the number of
+matching processes, not the processes that were successfully signaled or waited
+for.
+.TP
+\fB\-d\fR, \fB\-\-delimiter\fR \fIdelimiter\fP
+Sets the string used to delimit each process ID in the output (by default a
+newline).
+.RB ( pgrep
+only.)
+.TP
+\fB\-e\fR, \fB\-\-echo\fR
+Display name and PID of the process being killed.
+.RB ( pkill
+only.)
+.TP
+\fB\-f\fR, \fB\-\-full\fR
+The
+.I pattern
+is normally only matched against the process name.  When
+.B \-f
+is set, the full command line is used.
+.TP
+\fB\-g\fR, \fB\-\-pgroup\fR \fIpgrp\fP,...
+Only match processes in the process group IDs listed.  Process group 0 is
+translated into
+.BR pgrep 's,
+.BR pkill 's,
+or
+.BR pidwait 's
+own process group.
+.TP
+\fB\-G\fR, \fB\-\-group\fR \fIgid\fP,...
+Only match processes whose real group ID is listed.  Either the numerical or
+symbolical value may be used.
+.TP
+\fB\-i\fR, \fB\-\-ignore\-case\fR
+Match processes case-insensitively.
+.TP
+\fB\-l\fR, \fB\-\-list\-name\fR
+List the process name as well as the process ID.
+.RB ( pgrep
+only.)
+.TP
+\fB\-a\fR, \fB\-\-list\-full\fR
+List the full command line as well as the process ID.
+.RB ( pgrep
+only.)
+.TP
+\fB\-n\fR, \fB\-\-newest\fR
+Select only the newest (most recently started) of the matching processes.
+.TP
+\fB\-o\fR, \fB\-\-oldest\fR
+Select only the oldest (least recently started) of the matching processes.
+.TP
+\fB\-O\fR, \fB\-\-older\fR \fIsecs\fP
+Select processes older than secs.
+.TP
+\fB\-P\fR, \fB\-\-parent\fR \fIppid\fP,...
+Only match processes whose parent process ID is listed.
+.TP
+\fB\-s\fR, \fB\-\-session\fR \fIsid\fP,...
+Only match processes whose process session ID is listed.  Session ID 0
+is translated into
+.BR pgrep 's,
+.BR pkill 's,
+or
+.BR pidwait 's
+own session ID.
+.TP
+\fB\-t\fR, \fB\-\-terminal\fR \fIterm\fP,...
+Only match processes whose controlling terminal is listed.  The terminal name
+should be specified without the "/dev/" prefix.
+.TP
+\fB\-u\fR, \fB\-\-euid\fR \fIeuid\fP,...
+Only match processes whose effective user ID is listed.  Either the numerical
+or symbolical value may be used.
+.TP
+\fB\-U\fR, \fB\-\-uid\fR \fIuid\fP,...
+Only match processes whose real user ID is listed.  Either the numerical or
+symbolical value may be used.
+.TP
+\fB\-v\fR, \fB\-\-inverse\fR\fR
+Negates the matching.  This option is usually used in
+.BR pgrep 's
+or
+.BR pidwait 's
+context.  In
+.BR pkill 's
+context the short option is disabled to avoid accidental usage of the option.
+.TP
+\fB\-w\fR, \fB\-\-lightweight\fR\fR
+Shows all thread ids instead of pids in
+.BR pgrep 's
+or
+.BR pidwait 's
+context.  In
+.BR pkill 's
+context this option is disabled.
+.TP
+\fB\-x\fR, \fB\-\-exact\fR\fR
+Only match processes whose names (or command lines if \fB\-f\fR is specified)
+.B exactly
+match the
+.IR pattern .
+.TP
+\fB\-F\fR, \fB\-\-pidfile\fR \fIfile\fR
+Read \fIPID\fRs from \fIfile\fR.  This option is more useful for
+.B pkill
+or
+.B pidwait
+than
+.BR pgrep .
+.TP
+\fB\-L\fR, \fB\-\-logpidfile\fR
+Fail if pidfile (see \fB\-F\fR) not locked.
+.TP
+\fB\-r\fR, \fB\-\-runstates\fR \fID,R,S,Z,\fP...
+Match only processes which match the process state.
+.TP
+\fB\-A\fR, \fB\-\-ignore-ancestors\fR\fR
+Ignore all ancestors of
+.BR pgrep ,
+.BR pkill ,
+or
+.BR pidwait .
+For example, this can be useful when elevating with
+.BR sudo
+or similar tools.
+.TP
+\fB\-H\fR, \fB\-\-require\-handler\fR\fR
+Only match processes with a userspace signal handler present for the signal to
+be sent.
+.TP
+\fB\-\-cgroup \fIname\fP,...
+Match on provided control group (cgroup) v2 name. See
+.BR cgroups (8)
+.TP
+\fB\-\-ns \fIpid\fP
+Match processes that belong to the same namespaces. Required to run as
+root to match processes from other users. See \fB\-\-nslist\fR for how to
+limit which namespaces to match.
+.TP
+\fB\-\-nslist \fIname\fP,...
+Match only the provided namespaces. Available namespaces:
+ipc, mnt, net, pid, user, uts.
+.TP
+\fB\-q\fR, \fB\-\-queue \fIvalue\fP
+Use
+.BR sigqueue (3)
+rather than
+.BR kill (2)
+and the value argument is used to specify
+an integer to be sent with the signal. If the receiving process has
+installed a handler for this signal using the SA_SIGINFO flag to
+.BR sigaction (2),
+then it can obtain this data via the si_value field of the
+siginfo_t structure.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help and exit.
+.PD
+.SH OPERANDS
+.TP
+.I pattern
+Specifies an Extended Regular Expression for matching against the process
+names or command lines.
+.SH EXAMPLES
+Example 1: Find the process ID of the
+.B named

+.IP
+$ ps \-fp $(pgrep \-d, \-x xterm)
+.PP
+Example 4: Make all
+.B chrome
+processes run nicer:
+.IP
+$ renice +4 $(pgrep chrome)
+.SH "EXIT STATUS"
+.PD 0
+.TP
+0
+One or more processes matched the criteria. For
+.B pkill
+and
+.BR pidwait ,
+one or more

+.TP
+1
+No processes matched or none of them could be signalled.
+.TP
+2
+Syntax error in the command line.
+.TP
+3
+Fatal error: out of memory etc.
+.PD
+.SH NOTES
+The process name used for matching is limited to the 15 characters present in
+the output of /proc/\fIpid\fP/stat.  Use the \fB\-f\fR option to match against the
+complete command line, /proc/\fIpid\fP/cmdline. Threads may not have the
+same process name as the parent process but will have the same command line.
+.PP
+The running
+.BR pgrep ,
+.BR pkill ,
+or
+.B pidwait
+process will never report itself as a
+match.
+.PP
+The
+.B \-O \-\-older
+option will silently fail if \fI/proc\fR is mounted with the \fIsubset=pid\fR option.
+.SH BUGS
+The options
+.B \-n
+and
+.B \-o
+and
+.B \-v
+can not be combined.  Let

+.TH PIDOF 1 "2023-01-16" "" "User Commands"
+.SH NAME
+pidof \- find the process ID of a running program
+.SH SYNOPSIS
+.B pidof
+.RB [ \-s ]
+.RB [ \-c ]
+.RB [ \-q ]
+.RB [ \-w ]
+.RB [ \-x ]
+.RB [ \-o
+.IR omitpid[,omitpid...]... ]
+.RB [ \-t ]
+.RB [ \-S
+.IR separator ]
+.I program
+.IB [ program... ]
+.SH DESCRIPTION
+.B Pidof
+finds the process id's (pids) of the named programs. It prints those
+id's on the standard output.
+.SH OPTIONS
+.IP \fB\-s\fP
+Single shot - this instructs the program to only return one \fIpid\fP.
+.IP \fB\-c\fP
+Only return process ids that are running with the same root directory.
+This option is ignored for non-root users, as they will be unable to check
+the current root directory of processes they do not own.
+.IP \fB\-q\fP
+Quiet mode, suppress any output and only sets the exit status accordingly.
+.IP \fB\-w\fP
+Show also processes that do not have visible command line (e.g. kernel
+worker threads).
+.IP \fB\-x\fP
+Scripts too - this causes the program to also return process id's of
+shells running the named scripts.
+.IP "\fB-o\fP \fIomitpid\fP"
+Tells \fBpidof\fP to omit processes with that process id. The special
+pid \fB%PPID\fP can be used to name the parent process of the \fBpidof\fP
+program, in other words the calling shell or shell script.
+.IP \fB\-t\fP
+Shows all thread ids instead of pids.
+.IP "\fB-S\fP \fIseparator\fP"
+Use \fIseparator\fP as a separator put between pids. Used only when
+more than one pids are printed for the program.
+The \fB\-d\fR option is an alias for this option for sysvinit
+.B pidof
+compatibility.
+.SH "EXIT STATUS"
+.TP
+.B 0
+At least one program was found with the requested name.
+.TP
+.B 1
+No program was found with the requested name.
+
+.SH BUGS
+When using the \fB\-x\fP option,
+.B pidof
+only has a simple method for detecting scripts and will miss scripts that,
+for example, use env. This limitation is due to how the scripts look in
+the proc filesystem.

+.SH NAME
+procps \- API to access system level information in the /proc filesystem
+
+.SH SYNOPSIS
+Five distinct interfaces are represented in this synopsis and named after
+the files they access in the /proc pseudo filesystem:
+.BR diskstats ", " meminfo ", " slabinfo ", " stat " and " vmstat .
+
+.nf
+.RS +4
+#include <libproc2/\fBnamed_interface\fR.h>
+
+.RI "int\fB procps_new  \fR (struct info **" info );
+.RI "int\fB procps_ref  \fR (struct info  *" info );
+.RI "int\fB procps_unref\fR (struct info **" info );
+
+.RB "struct result *" procps_get " ("
+.RI "    struct info *" info ,
+.RI "[   const char *" name ",      ]   \fBdiskstats\fR api only"
+.RI "    enum item " item );
+
+.RB "struct stack *" procps_select " ("
+.RI "    struct info *" info ,
+.RI "[   const char *" name ",      ]   \fBdiskstats\fR api only"
+.RI "    enum item *" items ,
+.RI "    int " numitems );
+
+.RB "struct reaped *" procps_reap " ("
+.RI "    struct info *" info ,
+.RI "[   enum reap_type " what ",   ]   \fBstat\fR api only"
+.RI "    enum item *" items ,
+.RI "    int " numitems );
+
+.RB "struct stack **" procps_sort " ("
+.RI "    struct info *" info ,
+.RI "    struct stack *" stacks [],
+.RI "    int " numstacked ,
+.RI "    enum item " sortitem ,
+.RI "    enum sort_order " order );
+
+.fi
+
+The above functions and structures are generic but the specific
+\fBnamed_interface\fR would also be part of any identifiers.
+For example, `procps_new' would actually be `procps_\fBmeminfo\fR_new'
+and `info' would really be `\fBdiskstats\fR_info', etc.
+
+The same \fBnamed_interface\fR is used in each header file name with
+an appended `.h' suffix.
+
+Link with \fI\-lproc2\fP.
+
+.SH DESCRIPTION
+.SS Overview
+Central to these interfaces is a simple `result'
+structure reflecting an `item' plus its value (in a union
+with standard C language types as members).
+All `result' structures are automatically allocated and
+provided by the library.
+
+By specifying an array of `items', these structures can be
+organized as a `stack', potentially yielding many results
+with a single function call.
+Thus, a `stack' can be viewed as a variable length record
+whose content and order is determined solely by the user.
+
+As part of each interface there are two unique enumerators.
+The `noop' and `extra' items exist to hold user values.
+They are never set by the library, but the `extra'
+result will be zeroed with each library interaction.
+
+The \fBnamed_interface\fR header file will be an essential
+document during user program development.
+There you will find available items, their return type
+(the `result' struct member name) and the source for such values.
+Additional enumerators and structures are also documented there.
+
+.SS Usage
+The following would be a typical sequence of calls to
+these interfaces.
+
+.nf
+.RB "1. " procps_new()
+.RB "2. " procps_get() ", " procps_select() " or " procps_reap()
+.RB "3. " procps_unref()
+.fi
+
+The \fBget\fR function is used to retrieve a `result' structure for
+a single `item'.
+Alternatively, a \fBGET\fR macro is available when only the return
+value is of interest.
+
+The \fBselect\fR function can retrieve multiple `result' structures
+in a single `stack'.
+
+For unpredictable variable outcomes, the \fBdiskstats\fR, \fBslabinfo\fR
+and \fBstat\fR interfaces export a \fBreap\fR function.
+It is used to retrieve multiple `stacks' each containing multiple
+`result' structures.
+Optionally, a user may choose to \fBsort\fR those results.
+
+To exploit any `stack', and access individual `result' structures,
+a \fIrelative_enum\fR is required as shown in the \fBVAL\fR macro
+defined in the header file.
+Such values could be hard coded as: 0 through numitems-1.
+However, this need is typically satisfied by creating your own
+enumerators corresponding to the order of the `items' array.
+
+.SS Caveats
+The \fBnew\fR, \fBref\fR, \fBunref\fR, \fBget\fR and \fBselect\fR
+functions are available in all five interfaces.
+
+For the \fBnew\fR and \fBunref\fR functions, the address of an \fIinfo\fR
+struct pointer must be supplied.
+With \fBnew\fR it must have been initialized to NULL.
+With \fBunref\fR it will be reset to NULL if the reference count reaches zero.
+
+In the case of the \fBdiskstats\fR interface, a \fIname\fR parameter
+on the \fBget\fR and \fBselect\fR functions identifies a disk or
+partition name
+
+For the \fBstat\fR interface, a \fIwhat\fR parameter on the \fBreap\fR
+function identifies whether data for just CPUs or both CPUs and NUMA
+nodes is to be gathered.
+
+When using the \fBsort\fR function, the parameters \fIstacks\fR and
+\fInumstacked\fR would normally be those returned in the `reaped'
+structure.
+
+.SH RETURN VALUE
+.SS Functions Returning an `int'
+An error will be indicated by a negative number that
+is always the inverse of some well known errno.h value.
+
+Success is indicated by a zero return value.
+However, the \fBref\fR and \fBunref\fR functions return
+the current \fIinfo\fR structure reference count.
+
+.SS Functions Returning an `address'
+An error will be indicated by a NULL return pointer
+with the reason found in the formal errno value.
+
+Success is indicated by a pointer to the named structure.
+
+.SH DEBUGGING
+To aid in program development, there is a provision that can
+help ensure `result' member references agree with library
+expectations.
+It assumes that a supplied macro in the header file is
+used to access the `result' value.
+
+This feature can be activated through either of the following
+methods and any discrepancies will be written to \fBstderr\fR.
+
+.IP 1) 3
+Add CFLAGS='-DXTRA_PROCPS_DEBUG' to any other ./configure
+options employed.
+
+.IP 2) 3
+Add #include <procps/xtra-procps-debug.h> to any program
+\fIafter\fR the named interface includes.
+
+.PP
+This verification feature incurs substantial overhead.
+Therefore, it is important that it \fInot\fR be activated
+for a production/release build.

+.fi
+
+The \fBget\fR function is an iterator for successive PIDs/TIDs,
+returning those `items' previously identified via \fBnew\fR
+or \fBreset\fR.
+
+Two functions support unpredictable variable outcomes.
+The \fBreap\fR function gathers data for all processes while
+the \fBselect\fR function deals with specific PIDs or UIDs.
+Both can return multiple `stacks' each containing multiple `result'
+structures.
+Optionally, a user may choose to \fBsort\fR such results
+
+To exploit any `stack', and access individual `result' structures,
+a \fIrelative_enum\fR is required as shown in the \fBVAL\fR macro
+defined in the header file.
+Such values could be hard coded as: 0 through numitems-1.
+However, this need is typically satisfied by creating your own
+enumerators corresponding to the order of the `items' array.
+
+.SS Caveats
+The <pids> API differs from others in that those items
+of interest must be provided at \fBnew\fR or \fBreset\fR time,
+the latter being unique to this API.
+If either the \fIitems\fR or \fInumitems\fR parameter is zero at
+\fBnew\fR time, then \fBreset\fR becomes mandatory before
+issuing any other call.
+
+For the \fBnew\fR and \fBunref\fR functions, the address of an \fIinfo\fR
+struct pointer must be supplied.
+With \fBnew\fR it must have been initialized to NULL.
+With \fBunref\fR it will be reset to NULL if the reference count reaches zero.
+
+The \fBget\fR and \fBreap\fR functions use the \fIwhich\fR parameter
+to specify whether just tasks or both tasks and threads are to be fetched.
+
+The \fBselect\fR function requires an array of PIDs or UIDs as
+\fIthese\fR along with \fInumthese\fR to identify which processes
+are to be fetched.
+This function then operates as a subset of \fBreap\fR.
+
+When using the \fBsort\fR function, the parameters \fIstacks\fR and
+\fInumstacked\fR would normally be those returned in the `pids_fetch'
+structure.
+
+Lastly, a \fBfatal_proc_unmounted\fR function may be called before
+any other function to ensure that the /proc/ directory is mounted.
+As such, the \fIinfo\fR parameter would be NULL and the
+\fIreturn_self\fR parameter zero.
+If, however, some items are desired for the issuing program (a
+\fIreturn_self\fR other than zero) then the \fBnew\fR call must precede
+it to identify the \fIitems\fR and obtain the required \fIinfo\fR pointer.
+
+.SH RETURN VALUE
+.SS Functions Returning an `int'
+An error will be indicated by a negative number that
+is always the inverse of some well known errno.h value.
+
+Success is indicated by a zero return value.
+However, the \fBref\fR and \fBunref\fR functions return
+the current \fIinfo\fR structure reference count.
+
+.SS Functions Returning an `address'
+An error will be indicated by a NULL return pointer
+with the reason found in the formal errno value.
+
+Success is indicated by a pointer to the named structure.
+However, if one survives the \fBfatal_proc_unmounted\fR call,
+NULL is always returned when \fIreturn_self\fR is zero.
+
+.SH DEBUGGING
+To aid in program development, there are two procps-ng provisions
+that can be exploited.
+
+The first is a supplied file named `libproc.supp' which may be
+useful when developing a \fImulti-threaded\fR application.
+When used with the valgrind `--suppressions=' option, warnings
+associated with the procps library itself are avoided.
+
+Such warnings arise because the library handles heap based
+allocations in a thread-safe manner.
+A \fIsingle-threaded\fR application will not receive those warnings.
+
+The second provision can help ensure `result' member references
+agree with library expectations.
+It assumes that a supplied macro in the header file is
+used to access the `result' value.
+
+This feature can be activated through either of the following
+methods and any discrepancies will be written to \fBstderr\fR.
+
+.IP 1) 3
+Add CFLAGS='-DXTRA_PROCPS_DEBUG' to any other ./configure
+options your project may employ.
+
+.IP 2) 3
+Add #include <procps/xtra-procps-debug.h> to any program
+\fIafter\fR the #include <procps/pids.h>.
+
+.PP
+This verification feature incurs substantial overhead.
+Therefore, it is important that it \fInot\fR be activated
+for a production/release build.
+
+.SH ENVIRONMENT VARIABLE(S)
+The value set for the following is unimportant, just its presence.
+
+.IP LIBPROC_HIDE_KERNEL
+This will hide kernel threads which would otherwise be returned with a
+.BR procps_pids_get ", " procps_pids_select " or " procps_pids_reap
+call.

+.SH NAME
+ps \- report a snapshot of the current processes.
+.SH SYNOPSIS
+\fBps\fR [\,\fIoptions\/\fR]
+.SH DESCRIPTION
+.B ps
+displays information about a selection of the active processes.  If you want
+a repetitive update of the selection and the displayed information, use
+.B top
+instead.
+.P
+This version of
+.B ps
+accepts several kinds of options:
+.IP
+.PD 0
+.IP 1 4
+UNIX options, which may be grouped and must be preceded by a dash.
+.IP 2 4
+BSD options, which may be grouped and must not be used with a dash.
+.IP 3 4
+GNU long options, which are preceded by two dashes.
+.PD
+.PP
+Options of different types may be freely mixed, but conflicts can appear.
+There are some synonymous options, which are functionally identical, due to
+the many standards and
+.B ps
+implementations that this
+.B ps
+is compatible with.
+.P
+By default,
+.B ps
+selects all processes with the same effective user ID (euid=EUID) as the
+current user and associated with the same terminal as the invoker.  It
+displays the process ID (pid=PID), the terminal associated with the process
+(tname=TTY), the cumulated CPU time in [DD\-]hh:mm:ss format (time=TIME), and
+the executable name (ucmd=CMD).  Output is unsorted by default.
+.P
+The use of BSD\-style options will add process state (stat=STAT) to the
+default display and show the command args (args=COMMAND) instead of the
+executable name.  You can override this with the
+.B PS_FORMAT
+environment variable.  The use of BSD\-style options will also change the
+process selection to include processes on other terminals (TTYs) that are
+owned by you; alternately, this may be described as setting the selection to
+be the set of all processes filtered to exclude processes owned by other
+users or not on a terminal.  These effects are not considered when options
+are described as being "identical" below, so
+.B \-M
+will be considered identical to \fBZ\fR and so on.
+.P
+Except as described below, process selection options are additive.  The
+default selection is discarded, and then the selected processes are added to
+the set of processes to be displayed.  A process will thus be shown if it
+meets any of the given selection criteria.

+.SH "SIMPLE PROCESS SELECTION"
+.TP
+.B a
+Lift the BSD\-style "only yourself" restriction, which is imposed upon the
+set of all processes when some BSD\-style (without "\-") options are used or
+when the
+.B ps
+personality setting is BSD\-like.  The set of processes selected in this
+manner is in addition to the set of processes selected by other means.  An
+alternate description is that this option causes
+.B ps
+to list all processes with a terminal (tty), or to list all processes when
+used together with the
+.B x
+option.
+.TP
+.B \-A
+Select all processes.  Identical to

+.TP
+.B \-a
+Select all processes except both session leaders (see
+.IR getsid (2))
+and processes not associated with a terminal.
+.TP
+.B \-d
+Select all processes except session leaders.
+.TP
+.B \-\-deselect
+Select all processes except those that fulfill the specified conditions
+(negates the selection).  Identical to

+.TP
+.B g
+Really all, even session leaders.  This flag is obsolete and may be

+.TP
+.B \-N
+Select all processes except those that fulfill the specified conditions
+(negates the selection).  Identical to
+.BR \-\-deselect .
+.TP
+.B T
+Select all processes associated with this terminal.  Identical to the
+.B t
+option without any argument.
+.TP
+.B r
+Restrict the selection to only running processes.
+.TP
+.B x
+Lift the BSD\-style "must have a tty" restriction, which is imposed upon the
+set of all processes when some BSD\-style (without "\-") options are used or
+when the
+.B ps
+personality setting is BSD\-like.  The set of processes selected in this
+manner is in addition to the set of processes selected by other means.  An
+alternate description is that this option causes
+.B ps
+to list all processes owned by you (same EUID as
+.BR ps ),
+or to list all processes when used together with the
+.B a
+option.
+.PD
+.SH "PROCESS SELECTION BY LIST"
+These options accept a single argument in the form of a blank\-separated or
+comma\-separated list.  They can be used multiple times.  For example:

+Select by process group ID (PGID).
+.TP
+.BI \-C \ cmdlist
+Select by command name.  This selects the processes whose executable name is
+given in
+.IR cmdlist .
+NOTE: The command name is not the same as the command line. Previous versions
+of procps and the kernel truncated this command name to 15 characters. This
+limitation is no longer present in both. If you depended on matching only
+15 characters, you may no longer get a match.
+.TP
+.BI \-G \ grplist
+Select by real group ID (RGID) or name.  This selects the processes whose
+real group name or ID is in the
+.I grplist
+list.  The real group ID identifies the group of the user who created the
+process, see
+.IR getgid (2).
+.TP
+.BI \-g \ grplist
+Select by session OR by effective group name.  Selection by session is
+specified by many standards, but selection by effective group is the logical
+behavior that several other operating systems use.  This
+.B ps
+will select by session when the list is completely numeric (as sessions
+are).  Group ID numbers will work only when some group names are also
+specified.  See the
+.B \-s
+and
+.B \-\-group
+options.

+.TP
+.BI \-\-group \ grplist
+Select by effective group ID (EGID) or name.  This selects the processes
+whose effective group name or ID is in
+.IR grplist .
+The effective group ID describes the group whose file access permissions are
+used by the process (see
+.IR getegid (2)).
+The
+.B \-g
+option is often an alternative to
+.BR \-\-group .
+.TP

+That is, it selects processes that are children of those listed in
+.IR pidlist .
+.TP
+.BI q \ pidlist
+Select by process ID (quick mode).  Identical to
+.B \-q
+and
+.BR \-\-quick\-pid .
+.TP
+.BI \-q \ pidlist
+Select by PID (quick mode).
+This selects the processes whose process ID numbers appear in

+With this option \fBps\fR reads the necessary info only
+for the pids listed in the \fIpidlist\fR and doesn't apply
+additional filtering rules. The order of pids is unsorted
+and preserved. No additional selection options, sorting

+.TP
+.BI \-t \ ttylist
+Select by tty.  This selects the processes associated with the terminals
+given in

+.TH SLABTOP "1" "2021-03-11" "procps-ng" "User Commands"
+.SH NAME
+slabtop \- display kernel slab cache information in real time
+.SH SYNOPSIS
+.B slabtop
+[\fIoptions\fR]
+.SH DESCRIPTION
+.B slabtop
+displays detailed kernel slab cache information in real time.  It displays a
+listing of the top caches sorted by one of the listed sort criteria.  It also
+displays a statistics header filled with slab layer information.
+.SH OPTIONS
+Normal invocation of
+.B slabtop
+does not require any options.  The behavior, however, can be fine-tuned by
+specifying one or more of the following flags:
+.TP
+\fB\-d\fR, \fB\-\-delay\fR=\fIN\fR
+Refresh the display every
+.I n
+in seconds.  By default,
+.B slabtop
+refreshes the display every three seconds.  To exit the program, hit
+.BR q .
+This cannot be combined with the \fB-o\fR option.
+.TP
+\fB\-s\fR, \fB\-\-sort\fR=\fIS\fR
+Sort by \fIS\fR, where \fIS\fR is one of the sort criteria.
+.TP
+\fB\-o\fR, \fB\-\-once\fR
+Display the output once and then exit.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display usage information and exit.
+.SH SORT CRITERIA
+The following are valid sort criteria used to sort the individual slab caches
+and thereby determine what are the "top" slab caches to display.  The default
+sort criteria is to sort by the number of objects ("o").
+.PP
+The sort criteria can also be changed while
+.B slabtop
+is running by pressing the associated character.
+.TS
+l l l.
+\fBcharacter	description	header\fR
+a	number of active objects	ACTIVE
+b	objects per slab	OBJ/SLAB

+n	name	NAME\:
+o	number of objects	OBJS
+p	pages per slab	N/A
+s	object size	OBJ SIZE
+u	cache utilization	USE
+.TE
+.SH COMMANDS
+.B slabtop
+accepts keyboard commands from the user during use.  The following are
+supported.  In the case of letters, both cases are accepted.
+.PP
+Each of the valid sort characters are also accepted, to change the sort
+routine. See the section
+.BR "SORT CRITERIA" .
+.TP
+.BR <SPACEBAR>
+Refresh the screen.
+.TP
+.BR Q
+Quit the program.
+.SH FILES
+.TP
+.I /proc/slabinfo
+slab information
+.SH "SEE ALSO"
+.BR free (1),
+.BR ps (1),
+.BR top (1),
+.BR vmstat (8)
+.SH NOTES
+Currently,
+.B slabtop
+requires a 2.4 or later kernel (specifically, a version 1.1 or later
+.IR /proc/slabinfo ).
+Kernel 2.2 should be supported in the future.
+.PP
+The
+.B slabtop
+statistic header is tracking how many bytes of slabs are being
+used and is not a measure of physical memory.  The 'Slab' field in the
+\fI/proc/meminfo\fR file is tracking information about used slab physical memory.
+.PP
+The
+.B CACHE SIZE
+column is not accurate, it's the upper limit of memory used by specific slab. When system
+using slub (most common case) is under high memory pressure, there are slab order
+fallbacks, which means "pages per slab" is not constant and may decrease.
+.SH AUTHORS
+Written by Chris Rivera and Robert Love.
+.PP
+.B slabtop
+was inspired by Martin Bligh's perl script,
+.BR vmtop .

+.TH SYSCTL "8" "2023-08-19" "procps-ng" "System Administration"
+.SH NAME
+sysctl \- configure kernel parameters at runtime
+.SH SYNOPSIS
+.B sysctl
+[\fIoptions\fR] [\fIvariable\fR[\fB=\fIvalue\fR]] [...]
+.br
+.B sysctl \-p
+[\fIfile\fR or \fIregexp\fR] [...]
+.SH DESCRIPTION
+.B sysctl
+is used to modify kernel parameters at runtime.  The parameters available
+are those listed under \fI/proc/sys/\fR.  Procfs is required for
+.B sysctl
+support in Linux.  You can use
+.B sysctl
+to both read and write sysctl data.
+.SH PARAMETERS
+.TP
+.I variable
+The name of a key to read from.  An example is kernel.ostype.  The '/'
+separator is also accepted in place of a '.'.
+.TP
+.IR  variable = value
+To set a key, use the form
+.IR  variable = value
+where
+.I variable
+is the key and
+.I value
+is the value to set it to.  If the value contains quotes or characters
+which are parsed by the shell, you may need to enclose the value in double
+quotes.
+.TP
+\fB\-n\fR, \fB\-\-values\fR
+Use this option to disable printing of the key name when printing values.
+.TP
+\fB\-e\fR, \fB\-\-ignore\fR
+Use this option to ignore errors about unknown keys.
+.TP
+\fB\-N\fR, \fB\-\-names\fR
+Use this option to only print the names.  It may be useful with shells that
+have programmable completion.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Use this option to not display the values set to stdout.
+.TP
+\fB\-w\fR, \fB\-\-write\fR
+Force all arguments to be write arguments and print an error if
+they cannot be parsed this way.
+.TP
+\fB\-p\fR[\fIFILE\fR], \fB\-\-load\fR[=\fIFILE\fR]
+Load in \fBsysctl\fR settings from the file specified or \fI/etc/sysctl.conf\fR
+if none given.  Specifying \- as filename means reading data from standard
+input. Using this option will mean arguments to
+.B sysctl
+are files, which are read in the order they are specified.
+The file argument may be specified as regular expression.
+.TP
+\fB\-a\fR, \fB\-\-all\fR
+Display all values currently available.
+.TP
+\fB\-\-deprecated\fR
+Include deprecated parameters to
+.B \-\-all
+values listing.
+.TP
+\fB\-b\fR, \fB\-\-binary\fR
+Print value without new line.
+.TP
+\fB\-\-system\fR
+Load settings from all system configuration files. See the
+.B SYSTEM FILE PRECEDENCE
+section below.
+.TP
+\fB\-r\fR, \fB\-\-pattern\fR \fIpattern\fR
+Only apply settings that match
+.IR pattern .
+The
+.I pattern
+uses extended regular expression syntax.
+.TP

+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.SH SYSTEM FILE PRECEDENCE
+When using the \fB\-\-system\fR option,
+.B sysctl
+will read files from directories in the following list in given
+order from top to bottom. Once a file of a given filename is loaded, any
+file of the same name in subsequent directories is ignored.
+
+/etc/sysctl.d/*.conf
+.br
+/run/sysctl.d/*.conf
+.br
+/usr/local/lib/sysctl.d/*.conf
+.br
+/usr/lib/sysctl.d/*.conf
+.br
+/lib/sysctl.d/*.conf
+.br
+/etc/sysctl.conf
+
+All configuration files are sorted in lexicographic order, regardless of the
+directory they reside in. Configuration files can either be completely
+replaced (by having a new configuration file with the same name in a
+directory of higher priority) or partially replaced (by having a configuration
+file that is ordered later).
+.SH EXAMPLES
+/sbin/sysctl \-a
+.br
+/sbin/sysctl \-n kernel.hostname
+.br
+/sbin/sysctl \-w kernel.domainname="example.com"
+.br
+/sbin/sysctl \-p/etc/sysctl.conf
+.br
+/sbin/sysctl \-a \-\-pattern forward
+.br
+/sbin/sysctl \-a \-\-pattern forward$
+.br
+/sbin/sysctl \-a \-\-pattern 'net.ipv4.conf.(eth|wlan)0.arp'
+.br
+/sbin/sysctl \-\-pattern '\[char94]net.ipv6' \-\-system
+.SH DEPRECATED PARAMETERS
+The
+.B base_reachable_time
+and
+.B retrans_time
+are deprecated.  The
+.B sysctl
+command does not allow changing values of these
+parameters.  Users who insist to use deprecated kernel interfaces should push values
+to \fB/proc\fR file system by other means.  For example:
+.PP
+echo 256 > /proc/sys/net/ipv6/neigh/eth0/base_reachable_time
+.SH FILES
+.I /proc/sys
+.br
+.I /etc/sysctl.d/*.conf

+.TH SYSCTL.CONF "5" "2021-09-15" "procps-ng" "File Formats"
+.SH NAME
+sysctl.conf \- sysctl preload/configuration file
+.SH DESCRIPTION
+.B sysctl.conf
+is a simple file containing sysctl values to be read in and set by
+.BR sysctl .
+The syntax is simply as follows:
+.RS
+.sp
+.nf
+.ne 7
+# comment
+; comment
+
+token = value
+.fi
+.RE
+.PP
+Note that blank lines are ignored, and whitespace before and after a token or
+value is ignored, although a value can contain whitespace within.  Lines which
+begin with a \fI#\fR or \fI;\fR are considered comments and ignored.
+
+If a line begins with a single \-, any attempts to set the value that fail will be
+ignored.
+
+.SH NOTES
+As the
+.BR /etc/sysctl.conf
+file is used to override default kernel parameter values, only a small number of parameters is predefined in the file.
+Use
+.IR /sbin/sysctl\ \-a
+or follow
+.BR sysctl (8)
+to list all possible parameters. The description of individual parameters can be found in the kernel documentation.
+
+Maximum supported line length of the value is 4096 characters due
+to a limitation of \fI/proc\fR entries in Linux kernel.
+.SH EXAMPLE
+.RS
+.sp
+.nf
+.ne 7
+# sysctl.conf sample
+#
+  kernel.domainname = example.com
+; this one has a space which will be written to the sysctl!
+  kernel.modprobe = /sbin/mod probe

+.\" ......................................................................
+.SS Operation
+.\" ----------------------------------------------------------------------
+When operating \*(We, the two most important keys are the help (h or ?)
+key and quit (`q') key.
+Alternatively, you could simply use the traditional interrupt key (^C)
+when you're done.
+
+When started for the first time, you'll be presented with these traditional
+elements on the main \*(We screen: 1) Summary Area; 2) Fields/Columns Header;
+3) Task Area.
+Each of these will be explored in the sections that follow.
+There is also an Input/Message line between the Summary Area and Columns
+Header which needs no further explanation.
+
+The main \*(We screen is \fIgenerally\fR quite adaptive to changes in
+terminal dimensions under X-Windows.
+Other \*(We screens may be less so, especially those with static text.
+It ultimately depends, however, on your particular window manager and
+terminal emulator.
+There may be occasions when their view of terminal size and current contents
+differs from \*(We's view, which is always based on operating system calls.
+
+Following any re-size operation, if a \*(We screen is corrupted, appears
+incomplete or disordered, simply typing something innocuous like a
+punctuation character or cursor motion key will usually restore it.
+In extreme cases, the following sequence almost certainly will:
+.nf
+       \fIkey/cmd  objective \fR
+       ^Z       \fBsuspend\fR \*(We
+       fg       \fBresume\fR \*(We
+       <Left>   force a screen \fBredraw\fR (if necessary)
+.fi
+
+But if the display is still corrupted, there is one more step you could try.
+Insert this command after \*(We has been suspended but before resuming it.
+.nf
+       \fIkey/cmd  objective \fR
+       reset    restore your \fBterminal settings\fR
+.fi
+
+\*(NT the width of \*(We's display will be limited to \*(WX positions.
+Displaying all fields requires \*(WF characters.
+Remaining screen width is usually allocated to any variable width columns
+currently visible.
+The variable width columns, such as COMMAND, are noted in topic
+3a. DESCRIPTIONS of Fields.
+Actual output width may also be influenced by the \-w switch, which is
+discussed in topic 1. COMMAND\-LINE Options.
+
+Lastly, some of \*(We's screens or functions require the use of cursor
+motion keys like the standard \*(KAs plus the Home, End, PgUp and PgDn keys.
+If your terminal or emulator does not provide those keys, the following
+combinations are accepted as alternatives:
+.nf
+      \fI key      equivalent-keys \fR
+       Left     alt +\fB h \fR
+       Down     alt +\fB j \fR
+       Up       alt +\fB k \fR
+       Right    alt +\fB l \fR
+       Home     alt + ctrl +\fB h \fR
+       PgDn     alt + ctrl +\fB j \fR
+       PgUp     alt + ctrl +\fB k \fR
+       End      alt + ctrl +\fB l \fR
+.fi
+
+The \fBUp\fR and \fBDown\fR \*(KAs have special significance when prompted
+for line input terminated with the <Enter> key.
+Those keys, or their aliases, can be used to retrieve previous input lines
+which can then be edited and re-input.
+And there are four additional keys available with line oriented input.
+.nf
+      \fI key      special-significance \fR
+       Up       recall \fBolder\fR strings for re-editing
+       Down     recall \fBnewer\fR strings or \fBerase\fR entire line
+       Insert   toggle between \fBinsert\fR and \fBovertype\fR modes
+       Delete   character \fBremoved\fR at cursor, moving others left
+       Home     jump to \fBbeginning\fR of input line
+       End      jump to \fBend\fR of input line
+.fi
+
+.\" ......................................................................
+.SS Linux Memory Types
+.\" ----------------------------------------------------------------------
+For our purposes there are three types of memory, and one is optional.
+First is \*(MP, a limited resource where code and data must
+reside when executed or referenced.
+Next is the optional \*(MS, where modified (dirty) memory can be saved
+and later retrieved if too many demands are made on \*(MP.
+Lastly we have \*(MV, a nearly unlimited resource serving the
+following goals:
+
+.nf
+   1. abstraction, free from physical memory addresses/limits
+   2. isolation, every process in a separate address space
+   3. sharing, a single mapping can serve multiple needs
+   4. flexibility, assign a virtual address to a file
+.fi
+
+Regardless of which of these forms memory may take, all are managed as
+pages (typically 4096 bytes) but expressed by default in \*(We as
+KiB (kibibyte).
+The memory discussed under topic `2c. MEMORY Usage' deals with \*(MP
+and the \*(MS for the system as a whole.
+The memory reviewed in topic `3. FIELDS / Columns Display'
+embraces all three memory types, but for individual processes.
+
+For each such process, every memory page is restricted to a single
+quadrant from the table below.
+Both \*(MP and \*(MV can include any of the four, while the \*(MS only
+includes #1 through #3.
+The memory in quadrant #4, when modified, acts as its own dedicated \*(MS.
+
+.nf
+                              \fBPrivate\fR | \fBShared\fR
+                          \fB1\fR           |          \fB2\fR
+     \fBAnonymous\fR  . stack               |
+                . malloc()            |
+                . brk()/sbrk()        | . POSIX shm*
+                . mmap(PRIVATE, ANON) | . mmap(SHARED, ANON)
+               -----------------------+----------------------
+                . mmap(PRIVATE, fd)   | . mmap(SHARED, fd)
+   \fBFile-backed\fR  . pgms/shared libs    |
+                          \fB3\fR           |          \fB4\fR
+.fi
+
+The following may help in interpreting process level memory values displayed
+as scalable columns and discussed under topic `3a. DESCRIPTIONS of Fields'.
+
+.nf
+   %MEM \- simply RES divided by total \*(MP
+   CODE \- the `pgms' portion of quadrant \fB3\fR
+   DATA \- the entire quadrant \fB1\fR portion of VIRT plus all
+          explicit mmap file-backed pages of quadrant \fB3\fR
+   RES  \- anything occupying \*(MP which, beginning with
+          Linux-4.5, is the sum of the following three fields:
+          RSan \- quadrant \fB1\fR pages, which include any
+                 former quadrant \fB3\fR pages if modified
+          RSfd \- quadrant \fB3\fR and quadrant \fB4\fR pages
+          RSsh \- quadrant \fB2\fR pages
+   RSlk \- subset of RES which cannot be swapped out (any quadrant)
+   SHR  \- subset of RES (excludes \fB1\fR, includes all \fB2\fR & \fB4\fR, some \fB3\fR)
+   SWAP \- potentially any quadrant except \fB4\fR
+   USED \- simply the sum of RES and SWAP
+   VIRT \- everything in-use and/or reserved (all quadrants)
+.fi
+
+\*(NT Even though program images and shared libraries are considered
+\fIprivate\fR to a process, they will be accounted for as \fIshared\fR
+(SHR) by the kernel.

+.\" ----------------------------------------------------------------------
+This portion consists of a minimum of two lines.
+In an SMP environment, additional lines can reflect individual \*(PU
+state percentages.
+
+Line 1 shows total\fB tasks\fR or\fB threads\fR, depending on the state
+of the Threads-mode toggle.
+That total is further classified as:
+.nf
+    running; sleeping; stopped; zombie
+.fi
+
+Line 2 shows \*(PU state percentages based on the interval since the
+last refresh.
+
+As a default, percentages for these individual categories are displayed.
+Depending on your kernel version, the \fBst\fR field may not be shown.
+.nf
+    \fBus\fR : time running un-niced user processes
+    \fBsy\fR : time running kernel processes
+    \fBni\fR : time running niced user processes

+    \fBhi\fR : time spent servicing hardware interrupts
+    \fBsi\fR : time spent servicing software interrupts
+    \fBst\fR : time stolen from this vm by the hypervisor
+.fi
+
+The `sy' value above also reflects the time running a virtual \*(Pu
+for guest operating systems, including those that have been niced.
+
+Beyond the first tasks/threads line, there are alternate \*(PU display
+modes available via the 4-way `t' \*(CT.
+They show an abbreviated summary consisting of these elements:
+.nf
+              \fR a  \fR  b    \fR c \fR   d

+through exbibytes (EiB) depending on the scaling factor enforced
+with the `E' \*(CI. The /proc/meminfo source fields are shown in parenthesis.
+
+Line 1 reflects \*(MP, classified as:

+    free           ( SwapFree )
+    used           ( SwapTotal - SwapFree )
+    avail          ( MemAvailable, which is \*(MP )
+.fi
+
+The \fBavail\fR number on line 2 is an estimation of \*(MP available for
+starting new applications, without swapping.
+Unlike the \fBfree\fR field, it attempts to account for readily reclaimable
+page cache and memory slabs.
+It is available on kernels 3.14, emulated on kernels 2.6.27+, otherwise
+the same as \fBfree\fR.
+
+In the alternate memory display modes, two abbreviated summary lines

+    GiB Mem : \fB18.7\fR/15.738   [ ... ]
+    GiB Swap: \fB 0.0\fR/7.999    [ ... ]
+.fi
+
+Where: a) is the percentage used; b) is the total available; and c) is one of two
+visual graphs of those representations.
+
+In the case of \*(MP, the percentage represents the \fBtotal\fR minus the estimated

+Listed below are \*(We's available process fields (columns).
+They are shown in strict ascii alphabetical order.
+You may customize their position and whether or not they are displayable
+with the `f' (Fields Management) \*(CI.
+
+Any field is selectable as the sort field, and you control whether they
+are sorted high-to-low or low-to-high.
+For additional information on sort provisions
+\*(Xt 4c. TASK AREA Commands, SORTING.
+
+The fields related to \*(MP or \*(MV reference `(KiB)' which is the
+unsuffixed display mode.
+Such fields may, however, be scaled from KiB through PiB.
+That scaling is influenced via the `e' \*(CI or established for startup
+through a build option.
+
+.TP 4
+\fB%CPU \*(Em \*(PU Usage \fR
+The task's share of the elapsed \*(PU time since the last screen update,
+expressed as a percentage of total \*(PU time.
+
+In a true SMP environment, if a process is multi-threaded and \*(We is
+\fInot\fR operating in Threads mode, amounts greater than 100% may be
+reported.
+You toggle Threads mode with the `H' \*(CI.
+
+Also for multi-processor environments, if Irix mode is \*F, \*(We
+will operate in Solaris mode where a task's \*(Pu usage will be
+divided by the total number of \*(PUs.
+You toggle Irix/Solaris modes with the `I' \*(CI.
+
+\*(NT When running in forest view mode (`V') with children
+collapsed (`v'), this field will also include the \*(PU time of
+those unseen children.
+\*(XT 4c. TASK AREA Commands, CONTENT for more information regarding
+the `V' and `v' toggles.
+
+.TP 4
+\fB%CUC \*(Em \*(PU Utilization \fR
+This field is identical to %CUU below, except the percentage also
+reflects reaped child processes.
+
+.TP 4
+\fB%CUU \*(Em \*(PU Utilization \fR
+A task's total \*(PU usage divided by its elapsed running time,
+expressed as a percentage.
+
+If a process currently displays high \*(PU usage, this field can help
+determine if such behavior is normal.
+Conversely, if a process has low \*(PU usage currently, %CUU may reflect
+historically higher demands over its lifetime.
+
+.TP 4
+\fB%MEM \*(Em Memory Usage (RES) \fR
+A task's currently resident share of available \*(MP.
+
+\*(XX.
+
+.TP 4
+\fBAGID \*(Em Autogroup Identifier \fR
+The autogroup identifier associated with a process.
+This feature operates in conjunction with the CFS scheduler
+to improve interactive desktop performance.
+
+When /proc/sys/kernel/sched_autogroup_enabled is set, a new
+autogroup is created with each new session (\*(Xa SID).
+All subsequently forked processes in that session inherit membership in
+this autogroup.
+The kernel then attempts to equalize distribution of CPU cycles
+across such groups.
+Thus, an autogroup with many \*(PU intensive processes (e.g make -j)
+will not dominate an autogroup with only one or two processes.
+
+When -1 is displayed it means this information is not available.
+
+.TP 4
+\fBAGNI \*(Em Autogroup Nice Value \fR
+The autogroup nice value which affects scheduling of all processes
+in that group.
+A negative nice value means higher priority, whereas a positive nice
+value means lower priority.
+
+.TP 4
+\fBCGNAME \*(Em Control Group Name \fR
+The name of the control group to which a process belongs,
+or `\-' if not applicable for that process.
+
+This will typically be the last entry in the full list of control
+groups as shown under the next heading (CGROUPS).
+And as is true there, this field is also variable width.
+
+.TP 4
+\fBCGROUPS \*(Em Control Groups \fR
+The names of the control group(s) to which a process belongs,
+or `\-' if not applicable for that process.
+
+Control Groups provide for allocating resources (cpu, memory, network
+bandwidth, etc.) among installation-defined groups of processes.
+They enable fine-grained control over allocating, denying, prioritizing,
+managing and monitoring those resources.
+
+Many different hierarchies of cgroups can exist simultaneously on a system
+and each hierarchy is attached to one or more subsystems.
+A subsystem represents a single resource.
+
+\*(NT The CGROUPS field, unlike most columns, is not fixed-width.
+When displayed, it plus any other variable width columns will be allocated
+all remaining screen width (up to the maximum \*(WX characters).
+Even so, such variable width fields could still suffer truncation.
+\*(XT 5c. SCROLLING a Window for additional information on accessing
+any truncated data.
+
+.TP 4
+\fBCODE \*(Em Code Size (KiB) \fR

+as the Text Resident Set size or TRS.
+
+\*(XX.
+

+\fBCOMMAND \*(Em Command\fB Name\fR or Command\fB Line \fR
+Display the command line used to start a task or the name of the associated
+program.
+You toggle between command\fI line\fR and\fI name\fR with `c', which is both
+a \*(CO and an \*(CI.
+
+When you've chosen to display command lines, processes without a command
+line (like kernel threads) will be shown with only the program name in
+brackets, as in this example:

+
+This field may also be impacted by the forest view display mode.
+\*(XC `V' \*(CI for additional information regarding that mode.
+
+\*(NT The COMMAND field, unlike most columns, is not fixed-width.
+When displayed, it plus any other variable width columns will be allocated
+all remaining screen width (up to the maximum \*(WX characters).
+Even so, such variable width fields could still suffer truncation.
+This is especially true for this field when command lines are being
+displayed (the `c' \*(CI.)
+\*(XT 5c. SCROLLING a Window for additional information on accessing
+any truncated data.
+
+.TP 4
+\fBDATA \*(Em Data + Stack Size (KiB) \fR
+The amount of private memory \fIreserved\fR by a process.
+It is also known as the Data Resident Set or DRS.
+Such memory may not yet be mapped to \*(MP (RES) but will always be
+included in the \*(MV (VIRT) amount.
+
+\*(XX.
+
+.TP 4
+\fBELAPSED \*(Em Elapsed Running Time\fR
+The length of time since a process was started.
+Thus, the most recently started task will display the smallest time interval.
+
+The value will be expressed as `HH,MM' (hours,minutes) but is subject to
+additional scaling if the interval becomes too great to fit column width.
+At that point it will be scaled to `DD+HH' (days+hours) and possibly
+beyond.
+
+.TP 4
+\fBENVIRON \*(Em Environment variables \fR
+Display all of the environment variables, if any, as seen by the
+respective processes.
+These variables will be displayed in their raw native order, not the
+sorted order you are accustomed to seeing with an unqualified `set'.
+
+\*(NT The ENVIRON field, unlike most columns, is not fixed-width.
+When displayed, it plus any other variable width columns will be allocated
+all remaining screen width (up to the maximum \*(WX characters).
+Even so, such variable width fields could still suffer truncation.
+This is especially true for this field.
+\*(XT 5c. SCROLLING a Window for additional information on accessing
+any truncated data.
+

+\fBEXE \*(Em Executable Path \fR
+Where available, this is the full path to the executable,
+including the program name.
+
+\*(NT The EXE field, unlike most columns, is not fixed-width.
+When displayed, it plus any other variable width columns will be allocated
+all remaining screen width (up to the maximum \*(WX characters).
+
+.TP 4

+expressed in hexadecimal notation and with zeros suppressed.
+These flags are officially documented in <linux/sched.h>.
+
+.TP 4
+\fBGID \*(Em Group Id \fR
+The\fI effective\fR group ID.
+
+.TP 4
+\fBGROUP \*(Em Group Name \fR
+The\fI effective\fR group name.
+
+.TP 4
+\fBLOGID \*(Em Login User Id \fR
+The user ID used at\fI login\fR.
+When -1 is displayed it means this information is not available.
+
+.TP 4
+\fBLXC \*(Em Lxc Container Name \fR
+The name of the lxc container within which a task is running.
+If a process is not running inside a container, a dash (`\-') will be shown.
+
+.TP 4
+\fBNI \*(Em Nice Value \fR
+The nice value of the task.
+A negative nice value means higher priority, whereas a positive nice value
+means lower priority.
+Zero in this field simply means priority will not be adjusted in determining
+a task's dispatch-ability.
+
+\*(NT This value only affects scheduling priority relative to other processes
+in the same autogroup.
+\*(XC `AGID' and `AGNI' fields for additional information on autogroups.
+
+.TP 4
+\fBNU \*(Em Last known NUMA node \fR
+A number representing the NUMA node associated with the last used processor (`P').
+When -1 is displayed it means that NUMA information is not available.
+
+\*(XC `2' and `3' \*(CIs for additional NUMA provisions affecting the \*(SA.
+
+.TP 4
+\fBOOMa \*(Em Out of Memory Adjustment Factor \fR
+The value, ranging from -1000 to +1000, added to the current out of memory
+score (OOMs) which is then used to determine which task to kill when memory
+is exhausted.
+
+.TP 4
+\fBOOMs \*(Em Out of Memory Score \fR
+The value, ranging from 0 to +1000, used to select task(s) to kill when memory
+is exhausted.
+Zero translates to `never kill' whereas 1000 means `always kill'.
+
+.TP 4
+\fBP \*(Em Last used \*(PU (SMP) \fR
+A number representing the last used processor.
+In a true SMP environment this will likely change frequently since the kernel
+intentionally uses weak affinity.
+Also, the very act of running \*(We may break this weak affinity and cause more
+processes to change \*(PUs more often (because of the extra demand for
+\*(Pu time).
+
+.TP 4
+\fBPGRP \*(Em Process Group Id \fR
+Every process is member of a unique process group which is used for
+distribution of signals and by terminals to arbitrate requests for their
+input and output.
+When a process is created (forked), it becomes a member of the process
+group of its parent.
+By convention, this value equals the process ID (\*(Xa PID) of the first
+member of a process group, called the process group leader.
+
+.TP 4
+\fBPID \*(Em Process Id \fR
+The task's unique process ID, which periodically wraps, though never
+restarting at zero.
+In kernel terms, it is a dispatchable entity defined by a task_struct.
+
+This value may also be used as: a process group ID (\*(Xa PGRP);
+a session ID for the session leader (\*(Xa SID);
+a thread group ID for the thread group leader (\*(Xa TGID);
+and a TTY process group ID for the process group leader (\*(Xa TPGID).
+
+.TP 4
+\fBPPID \*(Em Parent Process Id \fR
+The process ID (pid) of a task's parent.
+
+.TP 4
+\fBPR \*(Em Priority \fR
+The scheduling priority of the task.
+If you see `rt' in this field, it means the task is running
+under real time scheduling priority.
+
+Under linux, real time priority is somewhat misleading since traditionally
+the operating itself was not preemptible.
+And while the 2.6 kernel can be made mostly preemptible, it is not always so.
+
+.TP 4
+\fBPSS \*(Em Proportional Resident Memory, smaps (KiB) \fR
+The proportion of this task's share of `RSS' where each page is divided by
+the number of processes sharing it.
+It is also the sum of the `PSan', `PSfd' and `PSsh' fields.
+
+For example, if a process has 1000 resident pages alone and 1000 resident
+pages shared with another process, its `PSS' would be 1500 (times page size).

+\*(ZX.
+.RE
+
+.TP 4
+\fBRES \*(Em Resident Memory Size (KiB) \fR
+A subset of the virtual address space (VIRT) representing the non-swapped
+\*(MP a task is currently using.
+It is also the sum of the `RSan', `RSfd' and `RSsh' fields.
+
+It can include private anonymous pages, private pages mapped to files
+(including program images and shared libraries) plus shared anonymous pages.
+All such memory is backed by the \*(MS represented separately under SWAP.
+
+Lastly, this field may also include shared file-backed pages which, when
+modified, act as a dedicated \*(MS and thus will never impact SWAP.
+
+\*(XX.
+
+.TP 4
+\fBRSS \*(Em Resident Memory, smaps (KiB) \fR

+    \fBT\fR = stopped by job control signal
+    \fBt\fR = stopped by debugger during trace
+    \fBZ\fR = zombie
+
+Tasks shown as running should be more properly thought of as ready to run
+\*(Em their task_struct is simply represented on the Linux run-queue.
+Even without a true SMP machine, you may see numerous tasks in this state
+depending on \*(We's delay interval and nice value.
+
+.TP 4
+\fBSHR \*(Em Shared Memory Size (KiB) \fR
+A subset of resident memory (RES) that may be used by other processes.
+It will include shared anonymous pages and shared file-backed pages.
+It also includes private pages mapped to files representing

+
+\*(XX.
+
+.TP 4
+\fBSID \*(Em Session Id \fR
+A session is a collection of process groups (\*(Xa PGRP),
+usually established by the login shell.
+A newly forked process joins the session of its creator.
+By convention, this value equals the process ID (\*(Xa PID) of the first
+member of the session, called the session leader, which is usually the
+login shell.
+
+.TP 4
+\fBSTARTED \*(Em Start Time Interval\fR
+The length of time since system boot when a process started.
+Thus, the most recently started task will display the largest time interval.
+
+The value will be expressed as `MM:SS' (minutes:seconds).
+But if the interval is too great to fit column width it will be scaled
+as `HH,MM' (hours,minutes) and possibly beyond.
+
+.TP 4
+\fBSUID \*(Em Saved User Id \fR
+The\fI saved\fR user ID.
+
+.TP 4
+\fBSUPGIDS \*(Em Supplementary Group IDs \fR
+The IDs of any supplementary group(s) established at login or

+They are displayed in a comma delimited list.
+
+\*(NT The SUPGIDS field, unlike most columns, is not fixed-width.
+When displayed, it plus any other variable width columns will be allocated

+\fBTGID \*(Em Thread Group Id \fR
+The ID of the thread group to which a task belongs.
+It is the PID of the thread group leader.
+In kernel terms, it represents those tasks that share an mm_struct.

+.TP 4
+\fBTIME \*(Em \*(PU Time \fR
+Total \*(PU time the task has used since it started.
+When Cumulative mode is \*O, each process is listed with the \*(Pu

+.TP 4
+\fBTTY \*(Em Controlling Tty \fR
+The name of the controlling terminal.
+This is usually the device (serial port, pty, etc.) from which the

+.TP 7
+\ \ <\fBEnter\fR> or <\fBSpace\fR>\ \ :\fIRefresh-Display \fR
+These commands awaken \*(We and following receipt of any input

+alters\fB both\fR the \*(SA and \*(TA for the \*(CW.
+While it is intended primarily for use with dumb terminals, it can be
+applied anytime.
+
+\*(NT When this toggle is \*O and \*(We is operating in monochrome mode,

+there will be no visual confirmation that they are even on.
+
+.TP 7
+*\ \ \fBd\fR | \fBs\fR\ \ :\fIChange-Delay-Time-interval \fR
+You will be prompted to enter the delay time, in seconds, between
+display updates.
+
+Fractional seconds are honored, but a negative number is not allowed.
+Entering 0 causes (nearly) continuous updates, with an unsatisfactory
+display as the system and tty driver try to keep up with \*(We's demands.
+The delay value is inversely proportional to system loading,
+so set it with care.
+
+If at any time you wish to know the current delay time, simply ask for
+help and view the system summary on the second line.

+.TP 7
+\ \ \ \fBE\fR\ \ :\fIEnforce-Summary-Memory-Scale\fR in Summary Area

+which ranges from KiB (kibibytes or 1,024 bytes) through EiB (exbibytes or
+1,152,921,504,606,846,976 bytes).
+
+If you see a `+' between a displayed number and the following label, it
+means that \*(We was forced to truncate some portion of that number.
+By raising the scaling factor, such truncation can be avoided.
+
+.TP 7
+\ \ \ \fBe\fR\ \ :\fIEnforce-Task-Memory-Scale\fR in Task Area
+With this command you can cycle through the available \*(TA memory scaling
+which ranges from KiB (kibibytes or 1,024 bytes) through PiB (pebibytes or
+1,125,899,906,842,624 bytes).
+
+While \*(We will try to honor the selected target range, additional
+scaling might still be necessary in order to accommodate current values.
+If you wish to see a more homogeneous result in the memory columns,
+raising the scaling range will usually accomplish that goal.
+Raising it too high, however, is likely to produce an all zero result
+which cannot be suppressed with the `0' \*(CI.
+
+.TP 7
+\ \ \ \fBg\fR\ \ :\fIChoose-Another-Window/Field-Group \fR

+\ \ \ \fBH\fR\ \ :\fIThreads-mode\fR toggle \fR
+When this toggle is \*O, individual threads will be displayed for all
+processes in all visible \*(TWs.
+Otherwise, \*(We displays a summation of all threads in each process.
+
+.TP 7
+\ \ \ \fBI\fR\ \ :\fIIrix/Solaris-Mode\fR toggle \fR
+When operating in Solaris mode (`I' toggled \*F), a task's \*(Pu usage
+will be divided by the total number of \*(PUs.

+You will be prompted for a PID and then the signal to send.
+
+Entering no PID or a negative number will be interpreted as
+the default shown in the prompt (the first task displayed).
+A PID value of zero means the \*(We program itself.
+
+The default signal, as reflected in the prompt, is SIGTERM.
+However, you can send any signal, via number or name.
+
+If you wish to abort the kill process, do one of the following
+depending on your progress:
+.nf
+    1) at the pid prompt, type an invalid number
+    2) at the signal prompt, type 0 (or any invalid signal)
+    3) at any prompt, type <Esc>
+.fi
+
+.TP 7
+\ \ \ \fBq\fR\ \ :\fIQuit \fR
+
+.TP 7

+You will be prompted for a PID and then the value to nice it to.
+
+Entering no PID or a negative number will be interpreted as
+the default shown in the prompt (the first task displayed).
+A PID value of zero means the \*(We program itself.
+
+A positive nice value will cause a process to lose priority.
+Conversely, a negative nice value will cause a process to be viewed
+more favorably by the kernel.
+As a general rule, ordinary users can only increase the nice value
+and are prevented from lowering it.
+
+If you wish to abort the renice process, do one of the following
+depending on your progress:

+restart later in exactly that same state.
+
+.TP 7
+\ \ \ \fBX\fR\ \ :\fIExtra-Fixed-Width \fR
+Some fields are fixed width and not scalable.
+As such, they are subject to truncation which would be indicated
+by a `+' in the last position.

+.fi
+
+You will be prompted for the amount to be added to the default

+Entering zero forces a return to those defaults.
+
+If you enter a negative number, \*(We will automatically increase
+the column size as needed until there is no more truncated data.

+A maximum of 8 \*(PUs per line can be displayed in this manner.

+This \*(CT is only active when the `t' toggle is \*O and the `1', `2',
+`3' and `!' toggles are \*F, thus showing individual \*(PU results.
+It assumes a platform has multiple cores of two distinct types,
+either multi-threaded (P-Core) or single-threaded (E-Core).
+
+While normally each \*(Pu is displayed as `%Cpu0, %Cpu1, ...', this
+toggle can be used to identify and/or filter those \*(Pus by their
+core type, either P-Core (performance) or E-Core (efficient).
+
+The 1st time `5' is struck, each \*(PU is displayed as `%Cp\fBP\fR'
+or `%Cp\fBE\fR' representing the two core types.
+The 2nd time, only P-Cores (%Cp\fBP\fR) will be shown.
+The 3rd time, only E-Cores (%Cp\fBE\fR) are displayed.
+When this \*(CT is struck for the 4th time, the \*(PU display
+returns to the normal `%Cpu' convention.

+This \*(CT is intended for massively parallel SMP environments where,
+even with the `4' \*(CT, not all processors can be displayed.
+With each press of `!' the number of \*(Pus combined is doubled thus
+reducing the total number of \*(Pu lines displayed.
+
+For example, with the first press of `!' two \*(Pus will be combined and
+displayed as `0-1, 2-3, ...' instead of the normal `%Cpu0, %Cpu1, %Cpu2,
+%Cpu3, ...'. With a second `!' \*(CT four \*(Pus are combined and shown
+as `0-3, 4-7, ...'.
+Then the third `!' press, combining eight \*(Pus, shows as `0-7, 8-15, ...',
+etc.

+You can use this `Other Filter' feature to establish selection criteria which
+will then determine which tasks are shown in the \*(CW.
+Such filters can be made persistent if preserved in the rcfile via
+the `W' \*(CI.
+
+Establishing a filter requires: 1) a field name; 2) an operator; and
+3) a selection value, as a minimum.
+This is the most complex of \*(We's user input requirements so, when you make
+a mistake, command recall will be your friend.
+Remember the Up/Down \*(KAs or their aliases when prompted for input.
+
+.B Filter Basics
+.RS +3
+.TP 3
+1. field names are case sensitive and spelled as in the header
+.TP 3
+2. selection values need not comprise the full displayed field
+.TP 3
+3. a selection is either case insensitive or sensitive to case
+.TP 3
+4. the default is inclusion, prepending `!' denotes exclusions
+.TP 3
+5. multiple selection criteria can be applied to a \*(TW
+.TP 3
+6. inclusion and exclusion criteria can be used simultaneously
+.TP 3
+7. the 1 equality and 2 relational filters can be freely mixed
+.TP 3
+8. separate unique filters are maintained for each \*(TW
+
+.PP
+If a field is not turned on or is not currently in view, then your selection
+criteria will not affect the display.
+Later, should a filtered field become visible, the selection criteria will
+then be applied.

+
+.PP
+.B Input Requirements
+.RS +3
+.P
+When prompted for selection criteria, the data you provide must take one
+of two forms.
+There are 3 required pieces of information, with a 4th as optional.
+These examples use spaces for clarity but your input generally would not.
+.nf
+        #1           \fB#2\fR  #3              ( required )
+        Field\-Name   ?   include\-if\-value
+     \fB!\fR  Field\-Name   ?   \fBexclude\fR\-if\-value
+     #4                                  ( optional )
+.fi
+
+Items #1, #3 and #4 should be self\-explanatory.
+Item \fB#2\fR represents both a required \fIdelimiter\fR and the \fIoperator\fR
+which must be one of either equality (`=') or relation (`<' or `>').
+
+The `=' equality operator requires only a partial match and that
+can reduce your `if\-value' input requirements.
+The `>' or `<' relational operators always employ string comparisons,
+even with numeric fields.
+They are designed to work with a field's default \fIjustification\fR and
+with homogeneous data.
+When some field's numeric amounts have been subjected to \fIscaling\fR
+while others have not, that data is no longer homogeneous.
+
+If you establish a relational filter and you \fBhave\fR changed the
+default Numeric or Character \fIjustification\fR, that filter is likely to fail.
+When a relational filter is applied to a memory field and you \fBhave not\fR
+changed the \fIscaling\fR, it may produce misleading results.
+This happens, for example, because `100.0m' (MiB) would appear greater
+than `1.000g' (GiB) when compared as strings.
+
+If your filtered results appear suspect, simply altering justification or
+scaling may yet achieve the desired objective.
+See the `j', `J' and `e' \*(CIs for additional information.
+.RE
+
+.B Potential Problems
+.RS +3
+.P
+These \fBGROUP\fR filters could produce the exact same results or the
+second one might not display anything at all, just a blank \*(TW.
+.nf
+     GROUP=root        ( only the same results when )
+     GROUP=ROOT        ( invoked via lower case `o' )
+.fi
+
+Either of these \fBRES\fR filters might yield inconsistent and/or
+misleading results, depending on the current memory scaling factor.
+Or both filters could produce the exact same results.
+.nf
+     RES>9999          ( only the same results when )
+     !RES<10000        ( memory scaling is at `KiB' )
+.fi
+
+This \fBnMin\fR filter illustrates a problem unique to scalable fields.
+This particular field can display a maximum of 4 digits, beyond which values
+are automatically scaled to KiB or above.
+So while amounts greater than 9999 exist, they will appear as 2.6m, 197k, etc.
+.nf
+     nMin>9999         ( always a blank \*(TW )
+.fi
+.RE
+
+.B Potential Solutions
+.RS +3
+.P
+These examples illustrate how Other Filtering can be creatively
+applied to achieve almost any desired result.
+Single quotes are sometimes shown to delimit the spaces which are part of
+a filter or to represent a request for status (^O) accurately.
+But if you used them with if-values in real life, no matches would be found.
+
+Assuming field \fBnTH\fR is displayed, the first filter will result in
+only multi-threaded processes being shown.
+It also reminds us that a trailing space is part of every displayed field.
+The second filter achieves the exact same results with less typing.
+.nf
+     !nTH=` 1 '                ( ` for clarity only )
+     nTH>1                     ( same with less i/p )
+.fi
+
+With Forest View mode active and the \fBCOMMAND\fR column in view, this
+filter effectively collapses child processes so that just 3 levels are shown.
+.nf
+     !COMMAND=`       `- '     ( ` for clarity only )
+.fi
+
+The final two filters appear as in response to the status request key (^O).
+In reality, each filter would have required separate input.
+The \fBPR\fR example shows the two concurrent filters necessary to display
+tasks with priorities of 20 or more, since some might be negative.
+Then by exploiting trailing spaces, the \fBnMin\fR series of filters could
+achieve the failed `9999' objective discussed above.
+.nf
+     `PR>20' + `!PR=-'         ( 2 for right result )
+     `!nMin=0 ' + `!nMin=1 ' + `!nMin=2 ' + `!nMin=3 ' ...

+.\" ----------------------------------------------------------------------
+.SS 6a. PERSONAL Configuration File
+.\" ----------------------------------------------------------------------
+This file is created or updated via the `W' \*(CI.
+
+The legacy version is written as `$HOME/.your\-name\-4\-\*(We' + `rc'
+with a leading period.
+
+A newly created \*(CF is written as procps/your\-name\-4\-\*(We' + `rc'
+without a leading period.
+The procps directory will be subordinate to either $XDG_CONFIG_HOME when
+set as an absolute path or the $HOME/.config directory.
+

+      "      # active `other filters' discussed in section 5e above
+      "      # plus `inspect' entries discussed in section 6b below
+.fi
+
+If a valid absolute path to the rcfile cannot be established, customizations
+made to a running \*(We will be impossible to preserve.
+
+.\" ......................................................................
+.SS 6b. ADDING INSPECT Entries
+.\" ----------------------------------------------------------------------
+To exploit the `Y' \*(CI, you must add entries at the\fB end\fR of the
+\*(We personal \*(CF.
+Such entries simply reflect a file to be read or command/pipeline to be
+executed whose results will then be displayed in a separate scrollable,
+searchable window.
+
+If you don't know the location or name of your \*(We rcfile, use the `W'
+\*(CI to rewrite it and note those details.
+
+Inspect entries can be added with a redirected echo or by editing the \*(CF.
+Redirecting an echo risks overwriting the rcfile should it replace (>)
+rather than append (>>) to that file.
+Conversely, when using an editor care must be taken not to corrupt existing
+lines, some of which could contain unprintable data or unusual characters
+depending on the \*(We version under which that \*(CF was saved.
+
+Those Inspect entries beginning with a `#' character are ignored, regardless
+of content.
+Otherwise they consist of the following 3 elements, each of which\fI must\fR
+be separated by a tab character (thus 2 `\\t' total):
+
+.nf
+  .type:  literal `file' or `pipe'
+  .name:  selection shown on the Inspect screen
+  .fmts:  string representing a path or command
+.fi
+
+The two types of Inspect entries are\fI not\fR interchangeable.
+Those designated `\fBfile\fR' will be accessed using fopen and
+must reference a single file in the `.fmts' element.
+Entries specifying `\fBpipe\fR' will employ popen, their `.fmts' element
+could contain many pipelined commands and, none can be interactive.
+
+If the file or pipeline represented in your `.fmts' deals with the specific PID
+input or accepted when prompted, then the format string must also contain
+the `\fB%d\fR' specifier, as these examples illustrate.
+
+.nf
+  .fmts=  /proc/\fI%d\fR/numa_maps
+  .fmts=  lsof -P -p\fI %d\fR
+.fi
+
+For `\fBpipe\fR' type entries only, you may also wish to redirect stderr to
+stdout for a more comprehensive result.
+Thus the format string becomes:
+
+.nf
+  .fmts=  pmap -x %d\fI 2>&1\fR
+.fi
+
+Here are examples of both types of Inspect entries as they might appear
+in the rcfile.
+The first entry will be ignored due to the initial `#' character.
+For clarity, the pseudo tab depictions (^I) are surrounded by an
+extra space but the actual tabs would not be.
+.nf
+
+  # pipe ^I Sockets ^I lsof -n -P -i 2>&1
+  pipe ^I Open Files ^I lsof -P -p %d 2>&1
+  file ^I NUMA Info ^I /proc/%d/numa_maps
+  pipe ^I Log ^I tail -n100 /var/log/syslog | sort -Mr
+.fi
+
+Except for the commented entry above, these next examples show what could
+be echoed to achieve similar results, assuming the rcfile name was `.toprc'.
+However, due to the embedded tab characters, each of these lines should be
+preceded by `\fB/bin/echo \-e\fR', not just a simple an `echo', to
+enable backslash interpretation regardless of which shell you use.
+
+.nf
+  "pipe\\tOpen Files\\tlsof -P -p %d 2>&1" >> ~/.toprc
+  "file\\tNUMA Info\\t/proc/%d/numa_maps" >> ~/.toprc
+  "pipe\\tLog\\ttail -n200 /var/log/syslog | sort -Mr" >> ~/.toprc
+.fi
+
+If any inspect entry you create produces output with unprintable characters
+they will be displayed in either the ^C notation or hexadecimal <FF> form,
+depending on their value.
+This applies to tab characters as well, which will show as `^I'.
+If you want a truer representation, any embedded tabs should be expanded.
+The following example takes what could have been a `file' entry but employs
+a `pipe' instead so as to expand the embedded tabs.
+
+.nf
+  # next would have contained `\\t' ...
+  # file ^I <your_name> ^I /proc/%d/status
+  # but this will eliminate embedded `\\t' ...
+  pipe ^I <your_name> ^I cat /proc/%d/status | expand \-
+.fi
+
+\*(NT Some programs might rely on \fISIGINT\fR to end.
+Therefore, if a `\fBpipe\fR' such as the following is established, one must
+use Ctrl-C to terminate it in order to review the results.
+This is the single occasion where a `^C' will not also terminate \*(We.
+
+.nf
+  pipe ^I Trace ^I /usr/bin/strace -p %d 2>&1
+.fi
+
+Lastly, while `\fBpipe\fR' type entries have been discussed in terms of pipelines
+and commands, there is nothing to prevent you from including \fI shell scripts\fR
+as well.
+Perhaps even newly created scripts designed specifically for the `Y' \*(CI.
+
+For example, as the number of your Inspect entries grows over time, the `Options:'
+row will be truncated when screen width is exceeded.
+That does not affect operation other than to make some selections invisible.
+However, if some choices are lost to truncation but you want to see more options,
+there is an easy solution hinted at below.
+
+.nf
+  Inspection Pause at pid ...
+  Use:  left/right then <Enter> ...
+  Options:  help  1  2  3  4  5  6  7  8  9  10  11 ...
+.fi
+
+The entries in the \*(We rcfile would have a number for the `.name' element and
+the `help' entry would identify a shell script you've written explaining what
+those numbered selections actually mean.
+In that way, many more choices can be made visible.

+This \*(CF represents defaults for users who have not saved their own \*(CF.

+
+.IP \(bu 3
+The user interface, through prompts and help, intentionally implies

+However, you're free to set any desired delay.
+If you want to see Linux at his scheduling best, try a delay of .09
+seconds or less.
+
+For this experiment, under x-windows open an xterm and maximize it.

+.fi

+Under an xterm using `white-on-black' colors, on \*(We's Color Mapping screen

+.B uptime
+[\fIoptions\fR]
+.SH DESCRIPTION
+.B uptime
+gives a one line display of the following information.  The current time, how
+long the system has been running, how many users are currently logged on, and
+the system load averages for the past 1, 5, and 15 minutes.
+.PP
+This is the same information contained in the header line displayed by
+.BR w (1).
+.PP
+System load averages is the average number of processes that are either in a
+runnable or uninterruptable state.  A process in a runnable state is either
+using the CPU or waiting to use the CPU.  A process in uninterruptable state
+is waiting for some I/O access, eg waiting for disk.  The averages are taken
+over the three time intervals.  Load averages are not normalized for the
+number of CPUs in a system, so a load average of 1 means a single CPU system
+is loaded all the time while on a 4 CPU system it means it was idle 75% of
+the time.

+.SH SYNOPSIS
+.B w
+[\fIoptions\fR] [\fIuser\fR]
+.SH DESCRIPTION
+.B w
+displays information about the users currently on the machine, and their
+processes.  The header shows, in this order, the current time, how long the
+system has been running, how many users are currently logged on, and the
+system load averages for the past 1, 5, and 15 minutes.
+.PP
+The following entries are displayed for each user: login name, the tty name,
+the remote host, login time, idle time, JCPU, PCPU, and the command line of
+their current process.
+.PP
+The JCPU time is the time used by all processes attached to the tty.  It does
+not include past background jobs, but does include currently running
+background jobs.

+.TH WATCH 1 "2023-01-17" "procps-ng" "User Commands"
+.SH NAME
+watch \- execute a program periodically, showing output fullscreen
+.SH SYNOPSIS
+.B watch
+[\fIoptions\fR] \fIcommand\fR
+.SH DESCRIPTION
+.B watch
+runs
+.I command
+repeatedly, displaying its output and errors (the first screenfull).  This
+allows you to watch the program output change over time.  By default,
+\fIcommand\fR is run every 2 seconds and \fBwatch\fR will run until interrupted.
+.SH OPTIONS
+.TP
+\fB\-b\fR, \fB\-\-beep\fR
+Beep if command has a non-zero exit.
+.TP
+\fB\-c\fR, \fB\-\-color\fR
+Interpret ANSI color and style sequences.
+.TP
+\fB\-C\fR, \fB\-\-no-color\fR
+Do not interpret ANSI color and style sequences.
+.TP
+\fB\-d\fR, \fB\-\-differences\fR[=\fIpermanent\fR]
+Highlight the differences between successive updates. If the optional
+\fIpermanent\fR argument is specified then
+.B watch
+will show all changes since the first iteration.
+.TP
+\fB\-e\fR, \fB\-\-errexit\fR
+Freeze updates on command error, and exit after a key press.
+.TP
+\fB\-g\fR, \fB\-\-chgexit\fR
+Exit when the output of
+.I command
+changes.
+.TP
+\fB\-n\fR, \fB\-\-interval\fR \fIseconds\fR
+Specify update interval.  The command will not allow quicker than 0.1 second
+interval, in which the smaller values are converted. Both '.' and ',' work
+for any locales. The \fBWATCH_INTERVAL\fR environment can be used to persistently
+set a non-default interval (following the same rules and formatting).
+.TP
+\fB\-p\fR, \fB\-\-precise\fR
+Make
+.BR watch
+attempt to run
+.I command
+every
+.B \-\-interval
+.IR seconds .
+Try it with
+.B ntptime
+(if present) and notice how the fractional seconds stays (nearly) the same, as opposed to
+normal mode where they continuously increase.
+.TP
+\fB\-q\fR, \fB\-\-equexit\fR <cycles>
+Exit when output of
+.I command
+does not change for the given number of cycles.
+.TP
+\fB\-r\fR, \fB\-\-no-rerun\fR
+Do not run the program on terminal resize, the output of the program will re-appear at the next
+regular run time.
+.TP
+\fB\-t\fR, \fB\-\-no\-title\fR
+Turn off the header showing the interval, command, and current time at the
+top of the display, as well as the following blank line.
+.TP
+\fB\-w\fR, \fB\-\-no\-wrap\fR
+Turn off line wrapping. Long lines will be truncated instead of wrapped to the next line.
+.TP
+\fB\-x\fR, \fB\-\-exec\fR
+Pass
+.I command
+to
+.BR exec (2)
+instead of
+.B sh \-c
+which reduces the need to use extra quoting to get the desired effect.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.TP
+\fB\-v\fR, \fB\-\-version\fR
+Display version information and exit.
+.SH "EXIT STATUS"
+.PP
+.RS
+.PD 0
+.TP
+.B 0
+Success.
+.TP
+.B 1
+Various failures.
+.TP
+.B 2
+Forking the process to watch failed.
+.TP
+.B 3
+Replacing child process stdout with write side pipe failed.
+.TP
+.B 4
+Command execution failed.
+.TP
+.B 5
+Closing child process write pipe failed.
+.TP
+.B 7
+IPC pipe creation failed.
+.TP
+.B 8
+Getting child process return value with
+.BR waitpid (2)
+failed, or command exited up on error.
+.TP
+.B other
+The watch will propagate command exit status as child exit status.
+.SH ENVIRONMENT
+The behavior of
+.B watch
+is affected by the following environment variables.
+
+.TP
+.B WATCH_INTERVAL
+Update interval, follows the same rules as the
+.B \-\-interval
+command line option.
+.sp
+.SH NOTES
+POSIX option processing is used (i.e., option processing stops at
+the first non\-option argument).  This means that flags after
+.I command
+don't get interpreted by
+.BR watch
+itself.
+.sp
+.SH BUGS
+Upon terminal resize, the screen will not be correctly repainted until the
+next scheduled update.  All
+.B \-\-differences
+highlighting is lost on that update as well. When using the
+.B \-\-no\-rerun
+option, no output of will be visible.
+
+Non-printing characters are stripped from program output.  Use \fBcat -v\fR as
+part of the command pipeline if you want to see them.
+
+Combining Characters that are supposed to display on the character at the
+last column on the screen may display one column early, or they may not
+display at all.
+
+Combining Characters never count as different in
+.B \-\-differences
+mode.  Only the base character counts.
+
+Blank lines directly after a line which ends in the last column do not
+display.
+
+.B \-\-precise
+mode doesn't yet have advanced temporal distortion technology to compensate
+for a
+.I command
+that takes more than
+.B \-\-interval
+.I seconds
+to execute.
+.B watch
+also can get into a state where it rapid-fires as many executions of
+.I command
+as it can to catch up from a previous executions running longer than
+.B \-\-interval
+(for example,
+.BR netstat (8)
+taking ages on a DNS lookup).
+.sp
+.SH EXAMPLES
+.PP
+To watch for mail, you might do
+.IP
+watch \-n 60 from
+.PP
+To watch the contents of a directory change, you could use
+.IP
+watch \-d ls \-l
+.PP
+If you're only interested in files owned by user joe, you might use
+.IP
+watch \-d 'ls \-l | fgrep joe'
+.PP
+To see the effects of quoting, try these out
+.IP
+watch echo $$
+.br
+watch echo '$$'
+.br
+watch echo "'"'$$'"'"
+.PP
+To see the effect of precision time keeping, try adding
+.B \-p
+to
+.IP
+watch \-n 10 sleep 1
+.PP
+You can watch for your administrator to install the latest kernel with
+.IP
+watch uname \-r
+.PP
+(Note that
+.B \-p
+isn't guaranteed to work across reboots, especially in the face of
+.B ntpdate
+(if present) or other bootup time-changing mechanisms)
