+.SH NAME
+getent \- get entries from Name Service Switch libraries
+.SH SYNOPSIS
+.nf
+.B getent [\fIoption\fP]... \fIdatabase\fP \fIkey\fP...
+.fi
+.SH DESCRIPTION
+The
+.B getent
+command displays entries from databases supported by the
+Name Service Switch libraries,
+which are configured in
+.IR /etc/nsswitch.conf .
+If one or more
+.I key
+arguments are provided,
+then only the entries that match the supplied keys will be displayed.
+Otherwise, if no
+.I key
+is provided, all entries will be displayed (unless the database does not
+support enumeration).
+.P
+The
+.I database
+may be any of those supported by the GNU C Library, listed below:
+.TP
+.B ahosts
+When no
+.I key
+is provided, use
+.BR sethostent (3),
+.BR gethostent (3),
+and
+.BR endhostent (3)
+to enumerate the hosts database.
+This is identical to using
+.BR hosts (5).
+When one or more
+.I key
+arguments are provided, pass each
+.I key
+in succession to
+.BR getaddrinfo (3)
+with the address family
+.BR AF_UNSPEC ,
+enumerating each socket address structure returned.
+.TP
+.B ahostsv4
+Same as
+.BR ahosts ,
+but use the address family
+.BR AF_INET .
+.TP
+.B ahostsv6
+Same as
+.BR ahosts ,
+but use the address family
+.BR AF_INET6 .
+The call to
+.BR getaddrinfo (3)
+in this case includes the
+.B AI_V4MAPPED
+flag.
+.TP
+.B aliases
+When no
+.I key
+is provided, use
+.BR setaliasent (3),
+.BR getaliasent (3),
+and
+.BR endaliasent (3)
+to enumerate the aliases database.
+When one or more
+.I key
+arguments are provided, pass each
+.I key
+in succession to
+.BR getaliasbyname (3)
+and display the result.
+.TP
+.B ethers
+When one or more
+.I key
+arguments are provided, pass each
+.I key
+in succession to
+.BR ether_aton (3)
+and
+.BR ether_hostton (3)
+until a result is obtained, and display the result.
+Enumeration is not supported on
+.BR ethers ,
+so a
+.I key
+must be provided.
+.TP
+.B group
+When no
+.I key
+is provided, use
+.BR setgrent (3),
+.BR getgrent (3),
+and
+.BR endgrent (3)
+to enumerate the group database.
+When one or more
+.I key
+arguments are provided, pass each numeric
+.I key
+to
+.BR getgrgid (3)
+and each nonnumeric
+.I key
+to
+.BR getgrnam (3)
+and display the result.
+.TP
+.B gshadow
+When no
+.I key
+is provided, use
+.BR setsgent (3),
+.BR getsgent (3),
+and
+.BR endsgent (3)
+to enumerate the gshadow database.
+When one or more
+.I key
+arguments are provided, pass each
+.I key
+in succession to
+.BR getsgnam (3)
+and display the result.
+.TP
+.B hosts
+When no
+.I key
+is provided, use
+.BR sethostent (3),
+.BR gethostent (3),
+and
+.BR endhostent (3)
+to enumerate the hosts database.
+When one or more
+.I key
+arguments are provided, pass each
+.I key
+to
+.BR gethostbyaddr (3)
+or
+.BR gethostbyname2 (3),
+depending on whether a call to
+.BR inet_pton (3)
+indicates that the
+.I key
+is an IPv6 or IPv4 address or not, and display the result.
+.TP
+.B initgroups
+When one or more
+.I key
+arguments are provided, pass each
+.I key
+in succession to
+.BR getgrouplist (3)
+and display the result.
+Enumeration is not supported on
+.BR initgroups ,
+so a
+.I key
+must be provided.
+.TP
+.B netgroup
+When one
+.I key
+is provided, pass the
+.I key
+to
+.BR setnetgrent (3)
+and, using
+.BR getnetgrent (3)
+display the resulting string triple
+.RI ( hostname ", " username ", " domainname ).
+Alternatively, three
+.I keys
+may be provided, which are interpreted as the
+.IR hostname ,
+.IR username ,
+and
+.I domainname
+to match to a netgroup name via
+.BR innetgr (3).
+Enumeration is not supported on
+.BR netgroup ,
+so either one or three
+.I keys
+must be provided.
+.TP
+.B networks
+When no
+.I key
+is provided, use
+.BR setnetent (3),

+.SH SYNOPSIS
+.B iconv
+.RI [ options ]
+.RI "[\-f " from-encoding "]"
+.RI "[\-t " to-encoding "]"
+.RI [ inputfile ]...
+.SH DESCRIPTION
+The
+.B iconv
+program reads in text in one encoding and outputs the text in another
+encoding.
+If no input files are given, or if it is given as a dash (\-),
+.B iconv
+reads from standard input.
+If no output file is given,
+.B iconv
+writes to standard output.
+.P
+If no
+.I from-encoding
+is given, the default is derived
+from the current locale's character encoding.
+If no
+.I to-encoding
+is given, the default is derived
+from the current locale's character
+encoding.
+.SH OPTIONS
+.TP
+.BI \-\-from\-code= from-encoding
+.TQ
+.BI \-f\~ from-encoding
+Use
+.I from-encoding
+for input characters.
+.TP
+.BI \-\-to\-code= to-encoding
+.TQ
+.BI \-t\~ to-encoding
+Use
+.I to-encoding
+for output characters.
+.IP
+If the string

+characters that cannot be converted are discarded and an error is
+printed after conversion.
+.IP
+If the string
+.B //TRANSLIT
+is appended to
+.IR to-encoding ,
+characters being converted are transliterated when needed and possible.
+This means that when a character cannot be represented in the target

+.SH EXIT STATUS
+Zero on success, nonzero on errors.
+.SH ENVIRONMENT
+Internally, the
+.B iconv
+program uses the
+.BR iconv (3)
+function which in turn uses
+.I gconv
+modules (dynamically loaded shared libraries)
+to convert to and from a character set.
+Before calling
+.BR iconv (3),
+the
+.B iconv
+program must first allocate a conversion descriptor using
+.BR iconv_open (3).
+The operation of the latter function is influenced by the setting of the
+.B GCONV_PATH
+environment variable:
+.IP \[bu] 3
+If
+.B GCONV_PATH
+is not set,
+.BR iconv_open (3)
+loads the system gconv module configuration cache file created by
+.BR iconvconfig (8)
+and then, based on the configuration,
+loads the gconv modules needed to perform the conversion.
+If the system gconv module configuration cache file is not available
+then the system gconv module configuration file is used.
+.IP \[bu]
+If
+.B GCONV_PATH
+is defined (as a colon-separated list of pathnames),
+the system gconv module configuration cache is not used.
+Instead,
+.BR iconv_open (3)
+first tries to load the configuration files by searching the directories in
+.B GCONV_PATH
+in order,
+followed by the system default gconv module configuration file.
+If a directory does not contain a gconv module configuration file,
+any gconv modules that it may contain are ignored.
+If a directory contains a gconv module configuration file
+and it is determined that a module needed for this conversion is
+available in the directory,
+then the needed module is loaded from that directory,
+the order being such that the first suitable module found in
+.B GCONV_PATH
+is used.
+This allows users to use custom modules and even replace system-provided
+modules by providing such modules in
+.B GCONV_PATH
+directories.
+.SH FILES
+.TP
+.I /usr/lib/gconv
+Usual default gconv module path.
+.TP
+.I /usr/lib/gconv/gconv\-modules
+Usual system default gconv module configuration file.
+.TP
+.I /usr/lib/gconv/gconv\-modules.cache
+Usual system gconv module configuration cache.
+.P
+Depending on the architecture,
+the above files may instead be located at directories with the path prefix
+.IR /usr/lib64 .
+.SH STANDARDS
+POSIX.1-2008.
+.SH HISTORY
+POSIX.1-2001.
+.SH EXAMPLES
+Convert text from the ISO/IEC\~8859-15 character encoding to UTF-8:
+.P
+.in +4n
+.EX
+$ \fBiconv \-f ISO\-8859\-15 \-t UTF\-8 < input.txt > output.txt\fP

+.TH intro 1 2024-05-02 "Linux man-pages (unreleased)"
+.SH NAME
+intro \- introduction to user commands
+.SH DESCRIPTION
+Section 1 of the manual describes user commands and tools,
+for example, file manipulation tools, shells, compilers,
+web browsers, file and image viewers and editors, and so on.
+.SH NOTES
+Linux is a flavor of UNIX, and as a first approximation
+all user commands under UNIX work precisely the same under
+Linux (and FreeBSD and lots of other UNIX-like systems).
+.P
+Under Linux, there are GUIs (graphical user interfaces), where you
+can point and click and drag, and hopefully get work done without
+first reading lots of documentation.
+The traditional UNIX environment
+is a CLI (command line interface), where you type commands to
+tell the computer what to do.
+That is faster and more powerful,
+but requires finding out what the commands are.
+Below a bare minimum, to get started.
+.SS Login
+In order to start working, you probably first have to open a session by
+giving your username and password.
+The program
+.BR login (1)
+now starts a
+.I shell
+(command interpreter) for you.
+In case of a graphical login, you get a screen with menus or icons
+and a mouse click will start a shell in a window.
+See also
+.BR xterm (1).
+.SS The shell
+One types commands to the
+.IR shell ,
+the command interpreter.
+It is not built-in, but is just a program
+and you can change your shell.
+Everybody has their own favorite one.
+The standard one is called
+.IR sh .
+See also
+.BR ash (1),
+.BR bash (1),
+.BR chsh (1),
+.BR csh (1),
+.BR dash (1),
+.BR ksh (1),
+.BR zsh (1).
+.P
+A session might go like:

+$
+.EE
+.in
+.P
+Here typing Control-D ended the session.
+.P
+The
+.B $
+here was the command prompt\[em]it is the shell's way of indicating
+that it is ready for the next command.
+The prompt can be customized
+in lots of ways, and one might include stuff like username,
+machine name, current directory, time, and so on.
+An assignment PS1="What next, master? "
+would change the prompt as indicated.
+.P
+We see that there are commands
+.I date
+(that gives date and time), and
+.I cal
+(that gives a calendar).
+.P
+The command
+.I ls
+lists the contents of the current directory\[em]it tells you what
+files you have.
+With a
+.I \-l
+option it gives a long listing,
+that includes the owner and size and date of the file, and the
+permissions people have for reading and/or changing the file.
+For example, the file "tel" here is 37 bytes long, owned by aeb
+and the owner can read and write it, others can only read it.
+Owner and permissions can be changed by the commands
+.I chown
+and
+.IR chmod .
+.P
+The command
+.I cat
+will show the contents of a file.
+(The name is from "concatenate and print": all files given as
+parameters are concatenated and sent to "standard output"
+(see
+.BR stdout (3)),
+here
+the terminal screen.)
+.P
+The command
+.I cp
+(from "copy") will copy a file.
+.P
+The command
+.I mv
+(from "move"), on the other hand, only renames it.
+.P
+The command
+.I diff
+lists the differences between two files.
+Here there was no output because there were no differences.
+.P
+The command
+.I rm
+(from "remove") deletes the file, and be careful! it is gone.
+No wastepaper basket or anything.
+Deleted means lost.
+.P
+The command
+.I grep
+(from "g/re/p") finds occurrences of a string in one or more files.
+Here it finds Maja's telephone number.
+.SS Pathnames and the current directory
+Files live in a large tree, the file hierarchy.
+Each has a
+.I "pathname"
+describing the path from the root of the tree (which is called
+.IR / )
+to the file.
+For example, such a full pathname might be
+.IR /home/aeb/tel .
+Always using full pathnames would be inconvenient, and the name
+of a file in the current directory may be abbreviated by giving
+only the last component.
+That is why
+.I /home/aeb/tel
+can be abbreviated
+to
+.I tel
+when the current directory is
+.IR /home/aeb .
+.P
+The command
+.I pwd
+prints the current directory.
+.P
+The command
+.I cd
+changes the current directory.
+.P
+Try alternatively
+.I cd
+and
+.I pwd
+commands and explore
+.I cd
+usage: "cd", "cd .", "cd ..", "cd /", and "cd \[ti]".
+.SS Directories
+The command
+.I mkdir
+makes a new directory.
+.P
+The command
+.I rmdir
+removes a directory if it is empty, and complains otherwise.
+.P
+The command
+.I find
+(with a rather baroque syntax) will find files with given name
+or other properties.
+For example, "find . \-name tel" would find
+the file
+.I tel
+starting in the present directory (which is called
+.IR . ).
+And "find / \-name tel" would do the same, but starting at the root
+of the tree.
+Large searches on a multi-GB disk will be time-consuming,
+and it may be better to use
+.BR locate (1).
+.SS Disks and filesystems
+The command
+.I mount
+will attach the filesystem found on some disk (or floppy, or CDROM or so)
+to the big filesystem hierarchy.
+And
+.I umount
+detaches it again.
+The command
+.I df
+will tell you how much of your disk is still free.
+.SS Processes
+On a UNIX system many user and system processes run simultaneously.
+The one you are talking to runs in the
+.IR foreground ,
+the others in the
+.IR background .
+The command
+.I ps
+will show you which processes are active and what numbers these
+processes have.
+The command
+.I kill
+allows you to get rid of them.
+Without option this is a friendly
+request: please go away.
+And "kill \-9" followed by the number
+of the process is an immediate kill.
+Foreground processes can often be killed by typing Control-C.
+.SS Getting information
+There are thousands of commands, each with many options.
+Traditionally commands are documented on
+.IR "man pages" ,
+(like this one), so that the command "man kill" will document
+the use of the command "kill" (and "man man" document the command "man").
+The program
+.I man
+sends the text through some
+.IR pager ,
+usually
+.IR less .
+Hit the space bar to get the next page, hit q to quit.
+.P
+In documentation it is customary to refer to man pages
+by giving the name and section number, as in
+.BR man (1).
+Man pages are terse, and allow you to find quickly some forgotten
+detail.
+For newcomers an introductory text with more examples
+and explanations is useful.
+.P
+A lot of GNU/FSF software is provided with info files.
+Type "info info"
+for an introduction on the use of the program
+.IR info .
+.P
+Special topics are often treated in HOWTOs.
+Look in
+.I /usr/share/doc/howto/en
+and use a browser if you find HTML files there.

+.SH NAME
+ldd \- print shared object dependencies
+.SH SYNOPSIS
+.nf
+.BR ldd " [\fIoption\fP]... \fIfile\fP..."
+.fi
+.SH DESCRIPTION
+.B ldd
+prints the shared objects (shared libraries) required by each program or
+shared object specified on the command line.
+An example of its use and output
+is the following:
+.P
+.in +4n
+.EX
+$ \fBldd /bin/ls\fP
+    linux\-vdso.so.1 (0x00007ffcc3563000)
+    libselinux.so.1 => /lib64/libselinux.so.1 (0x00007f87e5459000)
+    libcap.so.2 => /lib64/libcap.so.2 (0x00007f87e5254000)
+    libc.so.6 => /lib64/libc.so.6 (0x00007f87e4e92000)
+    libpcre.so.1 => /lib64/libpcre.so.1 (0x00007f87e4c22000)
+    libdl.so.2 => /lib64/libdl.so.2 (0x00007f87e4a1e000)
+    /lib64/ld\-linux\-x86\-64.so.2 (0x00005574bf12e000)
+    libattr.so.1 => /lib64/libattr.so.1 (0x00007f87e4817000)
+    libpthread.so.0 => /lib64/libpthread.so.0 (0x00007f87e45fa000)
+.EE
+.in
+.P
+In the usual case,
+.B ldd
+invokes the standard dynamic linker (see
+.BR ld.so (8))
+with the
+.B LD_TRACE_LOADED_OBJECTS
+environment variable set to 1.
+This causes the dynamic linker to inspect the program's dynamic dependencies,
+and find (according to the rules described in
+.BR ld.so (8))
+and load the objects that satisfy those dependencies.
+For each dependency,
+.B ldd
+displays the location of the matching object
+and the (hexadecimal) address at which it is loaded.
+(The
+.I linux\-vdso
+and
+.I ld\-linux
+shared dependencies are special; see
+.BR vdso (7)
+and
+.BR ld.so (8).)
+.\"
+.SS Security
+Be aware that in some circumstances
+(e.g., where the program specifies an ELF interpreter other than
+.IR ld\-linux.so ),
+.\" The circumstances are where the program has an interpreter
+.\" other than ld-linux.so. In this case, ldd tries to execute the
+.\" program directly with LD_TRACE_LOADED_OBJECTS=1, with the
+.\" result that the program interpreter gets control, and can do
+.\" what it likes, or pass control to the program itself.
+.\" Much more detail at
+.\" http://www.catonmat.net/blog/ldd-arbitrary-code-execution/
+some versions of
+.B ldd
+may attempt to obtain the dependency information
+by attempting to directly execute the program,
+which may lead to the execution of whatever code is defined
+in the program's ELF interpreter,
+and perhaps to execution of the program itself.
+.\" Mainline glibc's ldd allows this possibility (the line
+.\"      try_trace "$file"
+.\" in glibc 2.15, for example), but many distro versions of
+.\" ldd seem to remove that code path from the script.
+(Before glibc 2.27,
+.\" glibc commit eedca9772e99c72ab4c3c34e43cc764250aa3e3c
+the upstream
+.B ldd
+implementation did this for example,
+although most distributions provided a modified version that did not.)
+.P
+Thus, you should
+.I never
+employ
+.B ldd
+on an untrusted executable,
+since this may result in the execution of arbitrary code.
+A safer alternative when dealing with untrusted executables is:
+.P
+.in +4n
+.EX
+$ \fBobjdump \-p /path/to/program | grep NEEDED\fP
+.EE
+.in
+.P
+Note, however, that this alternative shows only the direct dependencies
+of the executable, while
+.B ldd
+shows the entire dependency tree of the executable.
+.SH OPTIONS

+.BR locale " [\fIoption\fP] " \-m
+.BR locale " [\fIoption\fP] \fIname\fP..."
+.fi
+.SH DESCRIPTION
+The
+.B locale
+command displays information about the current locale, or all locales,
+on standard output.
+.P
+When invoked without arguments,
+.B locale
+displays the current locale settings for each locale category (see
+.BR locale (5)),
+based on the settings of the environment variables that control the locale
+(see
+.BR locale (7)).
+Values for variables set in the environment are printed without double
+quotes, implied values are printed with double quotes.
+.P
+If either the
+.B \-a
+or the
+.B \-m
+option (or one of their long-format equivalents) is specified,
+the behavior is as follows:
+.TP
+.B \-\-all\-locales
+.TQ
+.B \-a
+Display a list of all available locales.
+The
+.B \-v
+option causes the
+.B LC_IDENTIFICATION
+metadata about each locale to be included in the output.
+.TP
+.B \-\-charmaps
+.TQ
+.B \-m
+Display the available charmaps (character set description files).
+To display the current character set for the locale, use
+\fBlocale \-c charmap\fR.
+.P
+The
+.B locale
+command can also be provided with one or more arguments,
+which are the names of locale keywords (for example,
+.IR date_fmt ,
+.IR ctype\-class\-names ,
+.IR yesexpr ,
+or
+.IR decimal_point )
+or locale categories (for example,
+.B LC_CTYPE
+or
+.BR LC_TIME ).
+For each argument, the following is displayed:
+.IP \[bu] 3
+For a locale keyword, the value of that keyword to be displayed.
+.IP \[bu]
+For a locale category,
+the values of all keywords in that category are displayed.
+.P
+When arguments are supplied, the following options are meaningful:
+.TP
+.B \-\-category\-name
+.TQ
+.B \-c
+For a category name argument,
+write the name of the locale category
+on a separate line preceding the list of keyword values for that category.
+.IP
+For a keyword name argument,
+write the name of the locale category for this keyword
+on a separate line preceding the keyword value.
+.IP
+This option improves readability when multiple name arguments are specified.
+It can be combined with the
+.B \-k
+option.
+.TP
+.B \-\-keyword\-name
+.TQ
+.B \-k
+For each keyword whose value is being displayed,
+include also the name of that keyword,
+so that the output has the format:
+.IP
+.in +4n
+.EX
+.IR keyword =\[dq] value \[dq]
+.EE
+.in
+.P
+The
+.B locale
+command also knows about the following options:
+.TP
+.B \-\-verbose
+.TQ
+.B \-v
+Display additional information for some command-line option and argument
+combinations.
+.TP
+.B \-\-help
+.TQ
+.B \-?
+Display a summary of command-line options and arguments and exit.
+.TP
+.B \-\-usage

+.SH DESCRIPTION
+The
+.B localedef
+program reads the indicated
+.I charmap
+and
+.I input
+files,
+compiles them to a binary form quickly usable by the
+locale functions in the C library
+.RB ( setlocale (3),
+.BR localeconv (3),
+etc.),
+and places the output in
+.IR outputpath .
+.P
+The
+.I outputpath
+argument is interpreted as follows:
+.IP \[bu] 3
+If
+.I outputpath
+contains a slash character ('/'),
+it is interpreted as the name of the
+directory where the output definitions are to be stored.
+In this case,
+there is a separate output file for each locale category
+.RI ( LC_TIME ,
+.IR LC_NUMERIC ,
+and so on).
+.IP \[bu]
+If the
+.B \-\-no\-archive
+option is used,
+.I outputpath
+is the name of a subdirectory in
+.I /usr/lib/locale
+where per-category compiled files are placed.
+.IP \[bu]
+Otherwise,
+.I outputpath
+is the name of a locale and the compiled locale data is added to the
+archive file
+.IR /usr/lib/locale/locale\-archive .
+A locale archive is a memory-mapped file which contains all the
+system-provided locales;
+it is used by all localized programs when the environment variable
+.B LOCPATH
+is not set.
+.P
+In any case,
+.B localedef
+aborts if the directory in which it tries to write locale files has
+not already been created.
+.P
+If no
+.I charmapfile
+is given,
+the value
+.I ANSI_X3.4\-1968
+(for ASCII) is used by default.
+If no
+.I inputfile
+is given,
+or if it is given as a dash
+(\-),
+.B localedef
+reads from standard input.
+.SH OPTIONS
+.SS Operation-selection options
+A few options direct
+.B localedef
+to do something other than compile locale definitions.
+Only one of these options should be used at a time.
+.TP
+.B \-\-add\-to\-archive
+Add the
+.I compiledpath
+directories to the locale archive file.
+The directories should have been created by previous runs of
+.BR localedef ,
+using
+.BR \-\-no\-archive .
+.TP
+.B \-\-delete\-from\-archive
+Delete the named locales from the locale archive file.
+.TP
+.B \-\-list\-archive
+List the locales contained in the locale archive file.
+.SS Other options
+Some of the following options are sensible only for certain operations;
+generally,
+it should be self-evident which ones.
+Notice that
+.B \-f
+and
+.B \-c
+are reversed from what you might expect;
+that is,
+.B \-f
+is not the same as
+.BR \-\-force .
+.TP
+.BI \-f " charmapfile" "\fR, \fP\-\-charmap=" charmapfile
+Specify the file that defines the character set
+that is used by the input file.
+If
+.I charmapfile
+contains a slash character ('/'),
+it is interpreted as the name of the character map.
+Otherwise,
+the file is sought in the current directory
+and the default directory for character maps.
+If the environment variable
+.B I18NPATH
+is set,
+.I $I18NPATH/charmaps/
+and
+.I $I18NPATH/
+are also searched after the current directory.
+The default directory for character maps is printed by
+.BR "localedef \-\-help" .
+.TP
+.BI \-i " inputfile" "\fR, \fP\-\-inputfile=" inputfile
+Specify the locale definition file to compile.
+The file is sought in the current directory
+and the default directory for locale definition files.
+If the environment variable
+.B I18NPATH
+is set,
+.I $I18NPATH/locales/
+and
+.I $I18NPATH

+The default directory for locale definition files is printed by
+.BR "localedef \-\-help" .
+.TP
+.BI \-u " repertoirefile" "\fR, \fP\-\-repertoire\-map=" repertoirefile
+Read mappings from symbolic names to Unicode code points from
+.IR repertoirefile .
+If
+.I repertoirefile
+contains a slash character ('/'),
+it is interpreted as the pathname of the repertoire map.
+Otherwise,
+the file is sought in the current directory
+and the default directory for repertoire maps.
+If the environment variable
+.B I18NPATH
+is set,
+.I $I18NPATH/repertoiremaps/
+and
+.I $I18NPATH
+are also searched after the current directory.
+The default directory for repertoire maps is printed by
+.BR "localedef \-\-help" .
+.TP
+.BI \-A " aliasfile" "\fR, \fP\-\-alias\-file=" aliasfile
+Use

+to look up aliases for locale names.
+There is no default aliases file.
+.TP
+.B \-\-force
+.TQ
+.B \-c
+Write the output files even if warnings were generated about the input
+file.
+.TP
+.B \-\-verbose

+as a subdirectory in the same directory as the locale archive file,
+and create separate output files for locale categories in it.
+This is helpful to prevent system locale archive updates from overwriting
+custom locales created with
+.BR localedef .
+.TP
+.B \-\-no\-hard\-links
+Do not create hard links between installed locales.
+.TP
+.BI \-\-no\-warnings= warnings
+Comma-separated list of warnings to disable.
+Supported warnings are
+.I ascii
+and
+.IR intcurrsym .
+.TP
+.B \-\-posix
+Conform strictly to POSIX.
+Implies
+.BR \-\-verbose .
+This option currently has no other effect.
+POSIX conformance is assumed if the environment variable
+.B POSIXLY_CORRECT
+is set.
+.TP
+.BI \-\-prefix= pathname
+Set the prefix to be prepended to the full archive pathname.
+By default,
+the prefix is empty.
+Setting the prefix to
+.IR foo ,
+the archive would be placed in
+.IR foo/usr/lib/locale/locale\-archive .
+.TP
+.B \-\-quiet
+Suppress all notifications and warnings,
+and report only fatal errors.
+.TP
+.B \-\-replace
+Replace a locale in the locale archive file.
+Without this option,
+if the locale is in the archive file already,
+an error occurs.

+.SH NAME
+memusage \- profile memory usage of a program
+.SH SYNOPSIS
+.nf
+.BR memusage " [\fIoption\fR]... \fIprogram\fR [\fIprogramoption\fR]..."
+.fi
+.SH DESCRIPTION
+.B memusage
+is a bash script which profiles memory usage of the program,
+.IR program .
+It preloads the
+.B libmemusage.so
+library into the caller's environment (via the
+.B LD_PRELOAD
+environment variable; see
+.BR ld.so (8)).
+The
+.B libmemusage.so
+library traces memory allocation by intercepting calls to
+.BR malloc (3),
+.BR calloc (3),
+.BR free (3),
+and
+.BR realloc (3);
+optionally, calls to
+.BR mmap (2),
+.BR mremap (2),
+and
+.BR munmap (2)
+can also be intercepted.
+.P
+.B memusage
+can output the collected data in textual form, or it can use
+.BR memusagestat (1)
+(see the
+.B \-p
+option,  below)
+to create a PNG file containing graphical representation
+of the collected data.
+.SS Memory usage summary
+The "Memory usage summary" line output by
+.B memusage
+contains three fields:
+.RS 4
+.TP
+\fBheap total\fR
+Sum of \fIsize\fR arguments of all
+.BR malloc (3)
+calls,
+products of arguments (\fInmemb\fR*\fIsize\fR) of all
+.BR calloc (3)
+calls,
+and sum of \fIlength\fR arguments of all
+.BR mmap (2)
+calls.
+In the case of
+.BR realloc (3)
+and
+.BR mremap (2),
+if the new size of an allocation is larger than the previous size,
+the sum of all such differences (new size minus old size) is added.
+.TP
+.B "heap peak"
+Maximum of all \fIsize\fR arguments of
+.BR malloc (3),
+all products of \fInmemb\fR*\fIsize\fR of
+.BR calloc (3),
+all \fIsize\fR arguments of
+.BR realloc (3),
+.I length
+arguments of
+.BR mmap (2),
+and
+\fInew_size\fR arguments of
+.BR mremap (2).
+.TP
+.B "stack peak"
+Before the first call to any monitored function,
+the stack pointer address (base stack pointer) is saved.
+After each function call, the actual stack pointer address is read and
+the difference from the base stack pointer computed.
+The maximum of these differences is then the stack peak.
+.RE
+.P
+Immediately following this summary line, a table shows the number calls,
+total memory allocated or deallocated,
+and number of failed calls for each intercepted function.
+For
+.BR realloc (3)
+and
+.BR mremap (2),
+the additional field "nomove" shows reallocations that
+changed the address of a block,
+and the additional "dec" field shows reallocations that
+decreased the size of the block.
+For
+.BR realloc (3),
+the additional field "free" shows reallocations that
+caused a block to be freed (i.e., the reallocated size was 0).
+.P
+The "realloc/total memory" of the table output by
+.B memusage
+does not reflect cases where
+.BR realloc (3)
+is used to reallocate a block of memory
+to have a smaller size than previously.
+This can cause sum of all "total memory" cells (excluding "free")
+to be larger than the "free/total memory" cell.
+.SS Histogram for block sizes
+The "Histogram for block sizes" provides a breakdown of memory
+allocations into various bucket sizes.

+.SH DESCRIPTION
+The

+The profiling summary is created using previously generated
+profiling data in the (optional) second command-line argument.

+.TQ
+.B \-V
+Display the program version and exit.
+.SH STANDARDS
+GNU.
+.SH EXAMPLES
+The following example demonstrates the use of
+.BR sprof .
+The example consists of a main program that calls two functions
+in a shared object.
+First, the code of the main program:
+.P
+.in +4n
+.EX
+$ \fBcat prog.c\fP
+#include <stdlib.h>
+\&
+void x1(void);
+void x2(void);
+\&
+int
+main(int argc, char *argv[])
+{
+    x1();
+    x2();
+    exit(EXIT_SUCCESS);
+}
+.EE
+.in
+.P
+The functions
+.IR x1 ()
+and
+.IR x2 ()
+are defined in the following source file that is used to
+construct the shared object:
+.P
+.in +4n
+.EX
+$ \fBcat libdemo.c\fP
+#include <unistd.h>
+\&
+void
+consumeCpu1(int lim)
+{
+    for (unsigned int j = 0; j < lim; j++)
+	getppid();
+}
+\&
+void
+x1(void) {
+    for (unsigned int j = 0; j < 100; j++)
+	consumeCpu1(200000);
+}
+\&
+void
+consumeCpu2(int lim)
+{
+    for (unsigned int j = 0; j < lim; j++)
+	getppid();
+}
+\&
+void
+x2(void)
+{
+    for (unsigned int j = 0; j < 1000; j++)
+	consumeCpu2(10000);
+}
+.EE
+.in
+.P
+Now we construct the shared object with the real name
+.IR libdemo.so.1.0.1 ,
+and the soname
+.IR libdemo.so.1 :
+.P
+.in +4n
+.EX
+$ \fBcc \-g \-fPIC \-shared \-Wl,\-soname,libdemo.so.1 \e\fP
+        \fB\-o libdemo.so.1.0.1 libdemo.c\fP
+.EE
+.in
+.P
+Then we construct symbolic links for the library soname and
+the library linker name:
+.P
+.in +4n
+.EX
+$ \fBln \-sf libdemo.so.1.0.1 libdemo.so.1\fP
+$ \fBln \-sf libdemo.so.1 libdemo.so\fP
+.EE
+.in
+.P
+Next, we compile the main program, linking it against the shared object,
+and then list the dynamic dependencies of the program:
+.P
+.in +4n
+.EX
+$ \fBcc \-g \-o prog prog.c \-L. \-ldemo\fP
+$ \fBldd prog\fP
+	linux\-vdso.so.1 =>  (0x00007fff86d66000)

+	/lib64/ld\-linux\-x86\-64.so.2 (0x00007fd4dc51f000)
+.EE
+.in
+.P
+In order to get profiling information for the shared object,
+we define the environment variable
+.B LD_PROFILE
+with the soname of the library:
+.P
+.in +4n
+.EX
+$ \fBexport LD_PROFILE=libdemo.so.1\fP
+.EE
+.in
+.P
+We then define the environment variable
+.B LD_PROFILE_OUTPUT
+with the pathname of the directory where profile output should be written,
+and create that directory if it does not exist already:
+.P
+.in +4n
+.EX
+$ \fBexport LD_PROFILE_OUTPUT=$(pwd)/prof_data\fP
+$ \fBmkdir \-p $LD_PROFILE_OUTPUT\fP
+.EE
+.in
+.P
+.B LD_PROFILE
+causes profiling output to be
+.I appended
+to the output file if it already exists,
+so we ensure that there is no preexisting profiling data:
+.P
+.in +4n
+.EX
+$ \fBrm \-f $LD_PROFILE_OUTPUT/$LD_PROFILE.profile\fP
+.EE
+.in
+.P
+We then run the program to produce the profiling output,
+which is written to a file in the directory specified in
+.BR LD_PROFILE_OUTPUT :
+.P
+.in +4n
+.EX
+$ \fBLD_LIBRARY_PATH=. ./prog\fP
+$ \fBls prof_data\fP
+libdemo.so.1.profile
+.EE
+.in
+.P
+We then use the
+.B sprof \-p
+option to generate a flat profile with counts and ticks:
+.P
+.in +4n
+.EX
+$ \fBsprof \-p libdemo.so.1 $LD_PROFILE_OUTPUT/libdemo.so.1.profile\fP

+.SH NAME
+time \- time a simple command or give resource usage
+.SH SYNOPSIS
+.B time
+.RI [ option \~.\|.\|.\&] " command " [ argument \~.\|.\|.]
+.SH DESCRIPTION
+The
+.B time
+command runs the specified program
+.I command
+with the given arguments.
+When
+.I command
+finishes,
+.B time
+writes a message to standard error giving timing statistics
+about this program run.
+These statistics consist of (i) the elapsed real time
+between invocation and termination, (ii) the user CPU time
+(the sum of the
+.I tms_utime
+and
+.I tms_cutime
+values in a
+.I "struct tms"
+as returned by
+.BR times (2)),
+and (iii) the system CPU time (the sum of the
+.I  tms_stime
+and
+.I tms_cstime
+values in a
+.I "struct tms"
+as returned by
+.BR times (2)).
+.P
+Note: some shells (e.g.,
+.BR bash (1))
+have a built-in
+.B time
+command that provides similar information on the usage of time and
+possibly other resources.
+To access the real command, you may need to specify its pathname
+(something like
+.IR /usr/bin/time ).
+.SH OPTIONS
+.TP
+.B \-p
+When in the POSIX locale, use the precise traditional format
+.IP
+.in +4n
+.EX
+"real %f\enuser %f\ensys %f\en"
+.EE
+.in
+.IP
+(with numbers in seconds)
+where the number of decimals in the output for %f is unspecified
+but is sufficient to express the clock tick accuracy, and at least one.
+.SH EXIT STATUS
+If
+.I command
+was invoked, the exit status is that of
+.IR command .
+Otherwise, it is 127 if
+.I command
+could not be found, 126 if it could be found but could not be invoked,
+and some other nonzero value (1\[en]125) if something else went wrong.
+.SH ENVIRONMENT
+The variables
+.BR LANG ,
+.BR LC_ALL ,
+.BR LC_CTYPE ,
+.BR LC_MESSAGES ,
+.BR LC_NUMERIC ,
+and
+.B NLSPATH
+are used for the text and formatting of the output.
+.B PATH
+is used to search for
+.IR command .
+.SH GNU VERSION
+Below a description of the GNU 1.7 version of
+.BR time .
+Disregarding the name of the utility, GNU makes it output lots of
+useful information, not only about time used, but also on other
+resources like memory, I/O and IPC calls (where available).
+The output is formatted using a format string that can be specified
+using the
+.I \-f
+option or the
+.B TIME
+environment variable.
+.P
+The default format string is:
+.P
+.in +4n
+.EX
+%Uuser %Ssystem %Eelapsed %PCPU (%Xtext+%Ddata %Mmax)k
+%Iinputs+%Ooutputs (%Fmajor+%Rminor)pagefaults %Wswaps
+.EE
+.in
+.P
+When the
+.I \-p
+option is given, the (portable) output format is used:
+.P
+.in +4n
+.EX
+real %e
+user %U
+sys %S
+.EE
+.in
+.\"
+.SS The format string
+The format is interpreted in the usual printf-like way.
+Ordinary characters are directly copied, tab, newline,
+and backslash are escaped using \et, \en, and \e\e,
+a percent sign is represented by %%, and otherwise %
+indicates a conversion.
+The program
+.B time
+will always add a trailing newline itself.
+The conversions follow.
+All of those used by
+.BR tcsh (1)
+are supported.
+.P
+.B "Time"
+.TP
+.B %E
+Elapsed real time (in [hours:]minutes:seconds).
+.TP
+.B %e
+(Not in
+.BR tcsh (1).)
+Elapsed real time (in seconds).
+.TP
+.B %S
+Total number of CPU-seconds that the process spent in kernel mode.
+.TP
+.B %U
+Total number of CPU-seconds that the process spent in user mode.
+.TP
+.B %P
+Percentage of the CPU that this job got, computed as (%U + %S) / %E.
+.P
+.B "Memory"
+.TP
+.B %M
+Maximum resident set size of the process during its lifetime, in Kbytes.
+.TP
+.B %t
+(Not in
+.BR tcsh (1).)
+Average resident set size of the process, in Kbytes.
+.TP
+.B %K
+Average total (data+stack+text) memory use of the process,
+in Kbytes.
+.TP
+.B %D
+Average size of the process's unshared data area, in Kbytes.
+.TP
+.B %p
+(Not in
+.BR tcsh (1).)
+Average size of the process's unshared stack space, in Kbytes.
+.TP
+.B %X
+Average size of the process's shared text space, in Kbytes.
+.TP
+.B %Z
+(Not in
+.BR tcsh (1).)
+System's page size, in bytes.
+This is a per-system constant, but varies between systems.
+.TP
+.B %F
+Number of major page faults that occurred while the process was running.
+These are faults where the page has to be read in from disk.
+.TP
+.B %R
+Number of minor, or recoverable, page faults.
+These are faults for pages that are not valid but which have
+not yet been claimed by other virtual pages.
+Thus the data
+in the page is still valid but the system tables must be updated.
+.TP
+.B %W
+Number of times the process was swapped out of main memory.
+.TP
+.B %c
+Number of times the process was context-switched involuntarily
+(because the time slice expired).
+.TP
+.B %w
+Number of waits: times that the program was context-switched voluntarily,
+for instance while waiting for an I/O operation to complete.
+.P
+.B "I/O"
+.TP
+.B %I
+Number of filesystem inputs by the process.
+.TP
+.B %O
+Number of filesystem outputs by the process.
+.TP
+.B %r
+Number of socket messages received by the process.
+.TP
+.B %s
+Number of socket messages sent by the process.
+.TP
+.B %k
+Number of signals delivered to the process.
+.TP
+.B %C
+(Not in
+.BR tcsh (1).)
+Name and command-line arguments of the command being timed.
+.TP
+.B %x
+(Not in
+.BR tcsh (1).)
+Exit status of the command.
+.SS GNU options
+.TP
+.BI "\-f " format ", \-\-format=" format
+Specify output format, possibly overriding the format specified
+in the environment variable TIME.
+.TP
+.B "\-p, \-\-portability"
+Use the portable output format.
+.TP
+.BI "\-o " file ", \-\-output=" file
+Do not send the results to
+.IR stderr ,
+but overwrite the specified file.
+.TP
+.B "\-a, \-\-append"
+(Used together with \-o.) Do not overwrite but append.
+.TP
+.B "\-v, \-\-verbose"
+Give very verbose output about all the program knows about.
+.TP
+.B "\-q, \-\-quiet"
+Don't report abnormal program termination (where
+.I command
+is terminated by a signal) or nonzero exit status.
+.\"
+.SS GNU standard options
+.TP
+.B "\-\-help"
+Print a usage message on standard output and exit successfully.
+.TP
+.B "\-V, \-\-version"
+Print version information on standard output, then exit successfully.
+.TP
+.B "\-\-"
+Terminate option list.
+.SH BUGS
+Not all resources are measured by all versions of UNIX,
+so some of the values might be reported as zero.
+The present selection was mostly inspired by the data
+provided by 4.2 or 4.3BSD.
+.P
+GNU time version 1.7 is not yet localized.
+Thus, it does not implement the POSIX requirements.
+.P
+The environment variable
+.B TIME
+was badly chosen.
+It is not unusual for systems like
+.BR autoconf (1)
+or
+.BR make (1)
+to use environment variables with the name of a utility to override
+the utility to be used.
+Uses like MORE or TIME for options to programs
+(instead of program pathnames) tend to lead to difficulties.
+.P
+It seems unfortunate that
+.I \-o
+overwrites instead of appends.
+(That is, the
+.I \-a
+option should be the default.)
+.P
+Mail suggestions and bug reports for GNU
+.B time
+to
+.IR bug\-time@gnu.org .
+Please include the version of
+.BR time ,
+which you can get by running
+.P
+.in +4n
+.EX
+time \-\-version
+.EE
+.in
+.P
+and the operating system
+and C compiler you used.
