+.TH AGETTY 8 "February 2016" "util-linux" "System Administration"
+.SH NAME
+agetty \- alternative Linux getty
+
+.SH SYNOPSIS
+.B agetty
+[options]
+.IR port " [" baud_rate "...] [" term ]
+
+.SH DESCRIPTION
+.ad
+.fi
+\fBagetty\fP opens a tty port, prompts for a login name and invokes
+the /bin/login command.  It is normally invoked by \fBinit\fP(8).
+
+\fBagetty\fP has several \fInon-standard\fP features that are useful
+for hardwired and for dial-in lines:
+.IP \(bu
+Adapts the tty settings to parity bits and to erase, kill,
+end-of-line and uppercase characters when it reads a login name.
+The program can handle 7-bit characters with even, odd, none or space
+parity, and 8-bit characters with no parity.  The following special
+characters are recognized: Control-U (kill); DEL and
+backspace (erase); carriage return and line feed (end of line).
+See also the \fB\-\-erase\-chars\fP and \fB\-\-kill\-chars\fP options.
+.IP \(bu
+Optionally deduces the baud rate from the CONNECT messages produced by
+Hayes(tm)-compatible modems.
+.IP \(bu
+Optionally does not hang up when it is given an already opened line
+(useful for call-back applications).
+.IP \(bu
+Optionally does not display the contents of the \fI/etc/issue\fP file.
+.IP \(bu
+Optionally displays an alternative issue file or directory instead of \fI/etc/issue\fP or \fI/etc/issue.d\fP.
+.IP \(bu
+Optionally does not ask for a login name.
+.IP \(bu
+Optionally invokes a non-standard login program instead of
+\fI/bin/login\fP.
+.IP \(bu
+Optionally turns on hardware flow control.
+.IP \(bu
+Optionally forces the line to be local with no need for carrier detect.
+.PP
+This program does not use the \fI/etc/gettydefs\fP (System V) or
+\fI/etc/gettytab\fP (SunOS 4) files.
+.SH ARGUMENTS
+.na
+.nf
+.fi
+.ad
+.TP
+.I port
+A path name relative to the \fI/dev\fP directory.  If a "\-" is
+specified, \fBagetty\fP assumes that its standard input is
+already connected to a tty port and that a connection to a
+remote user has already been established.
+.sp
+Under System V, a "\-" \fIport\fP argument should be preceded
+by a "\-\-".
+.TP
+.IR baud_rate ,...
+A comma-separated list of one or more baud rates.  Each time
+\fBagetty\fP receives a BREAK character it advances through
+the list, which is treated as if it were circular.
+.sp
+Baud rates should be specified in descending order, so that the
+null character (Ctrl\-@) can also be used for baud-rate switching.
+.sp
+This argument is optional and unnecessary for \fBvirtual terminals\fP.
+.sp
+The default for \fBserial terminals\fP is keep the current baud rate
+(see \fB\-\-keep\-baud\fP) and if unsuccessful then default to '9600'.
+.TP
+.I term
+The value to be used for the TERM environment variable.  This overrides
+whatever init(8) may have set, and is inherited by login and the shell.
+.sp
+The default is 'vt100', or 'linux' for Linux on a virtual terminal,
+or 'hurd' for GNU Hurd on a virtual terminal.
+.SH OPTIONS
+.na
+.nf
+.fi
+.ad
+.TP
+\-8, \-\-8bits
+Assume that the tty is 8-bit clean, hence disable parity detection.
+.TP
+\-a, \-\-autologin \fIusername\fP
+Automatically log in the specified user without asking for a username or password.
+Using this option causes an \fB\-f \fIusername\fR option and argument to be
+added to the \fB/bin/login\fP command line.  See \fB\-\-login\-options\fR, which
+can be used to modify this option's behavior.
+
+Note that \fB\-\-autologin\fP may affect the way how agetty initializes the
+serial line, because on auto-login agetty does not read from the line and it
+has no opportunity optimize the line setting.
+.TP
+\-c, \-\-noreset
+Do not reset terminal cflags (control modes).  See \fBtermios\fP(3) for more
+details.
+.TP
+\-E, \-\-remote
+Typically the \fBlogin\fP(1) command is given a remote hostname when
+called by something such as \fBtelnetd\fP(8).  This option allows \fBagetty\fP
+to pass what it is using for a hostname to \fBlogin\fP(1) for use
+in \fButmp\fP(5).  See \fB\-\-host\fP, \fBlogin\fP(1), and \fButmp\fP(5).
+.IP
+If the \fB\-\-host\fP \fIfakehost\fP option is given, then an \fB\-h\fP
+\fIfakehost\fP option and argument are added to the \fB/bin/login\fP
+command line.
+.IP
+If the \fB\-\-nohostname\fR option is given, then an \fB\-H\fP option
+is added to the \fB/bin/login\fP command line.
+.IP
+See \fB\-\-login\-options\fR.
+.TP
+\-f, \-\-issue\-file \fIfile|directory\fP
+Display the contents of \fIfile\fP instead of \fI/etc/issue\fP.  If the
+specified path is a \fIdirectory\fP then displays all files with .issue file
+extension in version-sort order from the directory.  This allows custom
+messages to be displayed on different terminals.  The
+\-\-noissue option will override this option.
+.TP
+\-h, \-\-flow\-control
+Enable hardware (RTS/CTS) flow control.  It is left up to the
+application to disable software (XON/XOFF) flow protocol where
+appropriate.
+.TP
+\-H, \-\-host \fIfakehost\fP
+Write the specified \fIfakehost\fP into the utmp file.  Normally,
+no login host is given, since \fBagetty\fP is used for local hardwired
+connections and consoles.  However, this option can be useful for
+identifying terminal concentrators and the like.
+.TP
+\-i, \-\-noissue
+Do not display the contents of \fI/etc/issue\fP (or other) before writing the
+login prompt.  Terminals or communications hardware may become confused
+when receiving lots of text at the wrong baud rate; dial-up scripts
+may fail if the login prompt is preceded by too much text.
+.TP
+\-I, \-\-init\-string \fIinitstring\fP
+Set an initial string to be sent to the tty or modem before sending
+anything else.  This may be used to initialize a modem.  Non-printable
+characters may be sent by writing their octal code preceded by a
+backslash (\\).  For example, to send a linefeed character (ASCII 10,
+octal 012), write \\012.
+.TP
+\-J, \-\-noclear
+Do not clear the screen before prompting for the login name.
+By default the screen is cleared.
+.TP
+\-l, \-\-login\-program \fIlogin_program\fP
+Invoke the specified \fIlogin_program\fP instead of /bin/login.  This allows
+the use of a non-standard login program.  Such a program could, for example,
+ask for a dial-up password or use a different password file. See
+\fB\-\-login\-options\fP.
+.TP
+\-L, \-\-local\-line[=\fImode\fP]
+Control the CLOCAL line flag.  The optional \fImode\fP argument is 'auto', 'always' or 'never'.
+If the \fImode\fP argument is omitted, then the default is 'always'.  If the
+\-\-local\-line option is not given at all, then the default is 'auto'.
+.PP
+.RS
+.PD 1
+.TP
+\fIalways\fR
+Forces the line to be a local line with no need for carrier detect.  This
+can be useful when you have a locally attached terminal where the serial
+line does not set the carrier-detect signal.
+.TP
+\fInever\fR
+Explicitly clears the CLOCAL flag from the line setting and the
+carrier-detect signal is expected on the line.
+.TP
+\fIauto\fR
+The \fBagetty\fR default.  Does not modify the CLOCAL setting and follows
+the setting enabled by the kernel.
+.PD
+.RE
+.TP
+\-m, \-\-extract\-baud
+Try to extract the baud rate from the CONNECT status message
+produced by Hayes(tm)\-compatible modems.  These status
+messages are of the form: "<junk><speed><junk>".
+\fBagetty\fP assumes that the modem emits its status message at
+the same speed as specified with (the first) \fIbaud_rate\fP value
+on the command line.
+.sp
+Since the \fB\-\-extract\-baud\fP feature may fail on heavily-loaded
+systems, you still should enable BREAK processing by enumerating all
+expected baud rates on the command line.
+.TP
+\-\-list\-speeds
+Display supported baud rates.  These are determined at compilation time.
+.TP
+\-n, \-\-skip\-login
+Do not prompt the user for a login name.  This can be used in connection
+with the \fB\-\-login\-program\fP option to invoke a non-standard login
+process such as a BBS system.  Note that with the \fB\-\-skip\-login\fR
+option, \fBagetty\fR gets no input from the user who logs in and therefore
+will not be able to figure out parity, character size, and newline
+processing of the connection.  It defaults to space parity, 7 bit
+characters, and ASCII CR (13) end-of-line character.  Beware that the
+program that \fBagetty\fR starts (usually /bin/login) is run as root.
+.TP
+\-N, \-\-nonewline
+Do not print a newline before writing out /etc/issue.
+.TP
+\-o, \-\-login\-options "\fIlogin_options\fP"
+Options  and arguments that  are passed to \fBlogin\fP(1). Where \\u is
+replaced by the login name. For example:
+.RS
+.IP "" 4
+.B "\-\-login\-options '-h darkstar -- \\\u'"
+.PP
+See \fB\-\-autologin\fR, \fB\-\-login\-program\fR and \fB\-\-remote\fR.
+.PP
+Please read the SECURITY NOTICE below before using this option.
+.RE
+.TP
+\-p, \-\-login\-pause
+Wait for any key before dropping to the login prompt.  Can be combined
+with \fB\-\-autologin\fP to save memory by lazily spawning shells.
+.TP
+\-r, \-\-chroot \fIdirectory\fP
+Change root to the specified directory.
+.TP
+\-R, \-\-hangup
+Call vhangup() to do a virtual hangup of the specified terminal.
+.TP
+\-s, \-\-keep\-baud
+Try to keep the existing baud rate.  The baud rates from
+the command line are used when agetty receives a BREAK character.
+.TP
+\-t, \-\-timeout \fItimeout\fP
+Terminate if no user name could be read within \fItimeout\fP seconds.
+Use of this option with hardwired terminal lines is not recommended.
+.TP
+\-U, \-\-detect\-case
+Turn on support for detecting an uppercase-only terminal.  This setting
+will detect a login name containing only capitals as indicating an
+uppercase-only terminal and turn on some upper-to-lower case conversions.
+Note that this has no support for any Unicode characters.
+.TP
+\-w, \-\-wait\-cr
+Wait for the user or the modem to send a carriage-return or a
+linefeed character before sending the \fI/etc/issue\fP file (or others)
+and the login prompt.  This is useful with the \fB\-\-init\-string\fP
+option.
+.TP
+\-\-nohints
+Do not print hints about Num, Caps and Scroll Locks.
+.TP
+\-\-nohostname
+By default the hostname will be printed.  With this option enabled,
+no hostname at all will be shown.
+.TP
+\-\-long\-hostname
+By default the hostname is only printed until the first dot.  With
+this option enabled, the fully qualified hostname by \fBgethostname\fR(3P)
+or (if not found) by \fBgetaddrinfo\fR(3) is shown.
+.TP
+\-\-erase\-chars \fIstring\fP
+This option specifies additional characters that should be interpreted as a
+backspace ("ignore the previous character") when the user types the login name.
+The default additional \'erase\' has been \'#\', but since util-linux 2.23
+no additional erase characters are enabled by default.
+.TP
+\-\-kill\-chars \fIstring\fP
+This option specifies additional characters that should be interpreted as a
+kill ("ignore all previous characters") when the user types the login name.
+The default additional \'kill\' has been \'@\', but since util-linux 2.23
+no additional kill characters are enabled by default.
+.TP
+\-\-chdir \fIdirectory\fP
+Change directory before the login.
+.TP
+\-\-delay \fInumber\fP
+Sleep seconds before open tty.
+.TP
+\-\-nice \fInumber\fP
+Run login with this priority.
+.TP
+\-\-reload
+Ask all running agetty instances to reload and update their displayed prompts,
+if the user has not yet commenced logging in.  After doing so the command will
+exit.  This feature might be unsupported on systems without Linux
+.BR inotify (7).
+.TP
+\-\-version
+Display version information and exit.
+.TP
+\-\-help
+Display help text and exit.
+.PP
+.SH EXAMPLES
+This section shows examples for the process field of an entry in the
+\fI/etc/inittab\fP file.  You'll have to prepend appropriate values
+for the other fields.  See \fIinittab(5)\fP for more details.
+
+For a hardwired line or a console tty:
+
+.RS

+.RE
+
+For a Hayes modem with a fixed 115200 bps interface to the machine
+(the example init string turns off modem echo and result codes, makes
+modem/computer DCD track modem/modem DCD, makes a DTR drop cause a

+.RE
+
+.SH SECURITY NOTICE
+If you use the \fB\-\-login\-program\fP and \fB\-\-login\-options\fP options,
+be aware that a malicious user may try to enter lognames with embedded options,
+which then get passed to the used login program.  Agetty does check
+for a leading "\-" and makes sure the logname gets passed as one parameter
+(so embedded spaces will not create yet another parameter), but depending
+on how the login binary parses the command line that might not be sufficient.
+Check that the used login program cannot be abused this way.
+.PP
+Some  programs use "\-\-" to indicate that the rest of the commandline should
+not be interpreted as options.  Use this feature if available by passing "\-\-"
+before the username gets passed by \\u.
+
+.SH ISSUE FILES
+The default issue file is \fI/etc/issue\fP. If the file exists then agetty also
+checks for \fI/etc/issue.d\fP directory. The directory is optional extension to
+the default issue file and content of the directory is printed after
+\fI/etc/issue\fP content. If the \fI/etc/issue\fP does not exist than the
+directory is ignored. All files with .issue extension from the directory are
+printed in version-sort order. The directory allow to maintain 3rd-party
+messages independently on the primary system \fI/etc/issue\fP file.
+
+The default path maybe overridden by \fB\-\-issue\-file\fP option. In this case
+specified path has to be file or directory and the default \fI/etc/issue\fP as
+well as \fI/etc/issue.d\fP are ignored.
+
+The issue files may contain certain escape codes to display the system name, date, time
+etcetera.  All escape codes consist of a backslash (\\) immediately
+followed by one of the characters listed below.
+
+.TP
+4 or 4{\fIinterface\fR}
+Insert the IPv4 address of the specified network interface (for example: \\4{eth0}).
+If the \fIinterface\fR argument is not specified, then select the first fully
+configured (UP, non-LOCALBACK, RUNNING) interface.  If not any configured
+interface is found, fall back to the IP address of the machine's hostname.
+.TP
+6 or 6{\fIinterface\fR}
+The same as \\4 but for IPv6.
+.TP
+b
+Insert the baudrate of the current line.
+.TP
+d
+Insert the current date.
+.TP
+e or e{\fIname\fR}
+Translate the human-readable \fIname\fP to an escape sequence and insert it
+(for example: \\e{red}Alert text.\\e{reset}).  If the \fIname\fR argument is
+not specified, then insert \\033.  The currently supported names are: black,
+blink, blue, bold, brown, cyan,
+darkgray, gray, green, halfbright, lightblue, lightcyan, lightgray, lightgreen,
+lightmagenta, lightred, magenta, red, reset, reverse, and yellow.  All unknown
+names are silently ignored.
+.TP
+s
+Insert the system name (the name of the operating system).  Same as 'uname \-s'.
+See also the \\S escape code.
+.TP
+S or S{VARIABLE}
+Insert the VARIABLE data from \fI/etc/os-release\fP.  If this file does not exist
+then fall back to \fI/usr/lib/os-release\fP.  If the VARIABLE argument is not
+specified, then use PRETTY_NAME from the file or the system name (see \\s).
+This escape code allows to keep \fI/etc/issue\fP distribution and release
+independent.  Note that \\S{ANSI_COLOR} is converted to the real terminal
+escape sequence.
+.TP
+l
+Insert the name of the current tty line.
+.TP
+m
+Insert the architecture identifier of the machine.  Same as 'uname \-m'.
+.TP
+n
+Insert the nodename of the machine, also known as the hostname.  Same as 'uname \-n'.
+.TP
+o
+Insert the NIS domainname of the machine.  Same as 'hostname \-d'.
+.TP
+O
+Insert the DNS domainname of the machine.
+.TP
+r
+Insert the release number of the OS.  Same as 'uname \-r'.
+.TP
+t
+Insert the current time.
+.TP
+u
+Insert the number of current users logged in.
+.TP
+U
+Insert the string "1 user" or "<n> users" where <n> is the number of current
+users logged in.
+.TP
+v
+Insert the version of the OS, that is, the build-date and such.
+.PP
+An example.  On my system, the following \fI/etc/issue\fP file:
+.sp
+.na
+.RS
+.nf
+This is \\n.\\o (\\s \\m \\r) \\t
+.fi
+.RE
+.PP
+displays as:
+.sp
+.RS
+.nf
+This is thingol.orcan.dk (Linux i386 1.1.9) 18:29:30
+.fi
+.RE
+
+.SH FILES
+.na
+.TP
+.I /var/run/utmp
+the system status file.
+.TP
+.I /etc/issue
+printed before the login prompt.
+.TP
+.I /etc/os-release /usr/lib/os-release
+operating system identification data.
+.TP
+.I /dev/console
+problem reports (if syslog(3) is not used).
+.TP
+.I /etc/inittab
+\fIinit\fP(8) configuration file for SysV-style init daemon.
+.SH BUGS
+.ad
+.fi
+The baud-rate detection feature (the \fB\-\-extract\-baud\fP option) requires that
+\fBagetty\fP be scheduled soon enough after completion of a dial-in
+call (within 30 ms with modems that talk at 2400 baud).  For robustness,
+always use the \fB\-\-extract\-baud\fP option in combination with a multiple baud
+rate command-line argument, so that BREAK processing is enabled.
+
+The text in the \fI/etc/issue\fP file (or other) and the login prompt
+are always output with 7-bit characters and space parity.
+
+The baud-rate detection feature (the \fB\-\-extract\-baud\fP option) requires that
+the modem emits its status message \fIafter\fP raising the DCD line.
+.SH DIAGNOSTICS
+.ad
+.fi
+Depending on how the program was configured, all diagnostics are
+written to the console device or reported via the \fBsyslog\fR(3) facility.
+Error messages are produced if the \fIport\fP argument does not
+specify a terminal device; if there is no utmp entry for the
+current process (System V only); and so on.

+.TH MESG 1 "July 2014" "util-linux" "User Commands"
+.SH NAME
+mesg \- display (or do not display) messages from other users
+.SH SYNOPSIS
+.B mesg
+[option]
+.RB [ n | y ]
+.SH DESCRIPTION
+The
+.B mesg
+utility is invoked by a user to control write access others have to the
+terminal device associated with standard error output.  If write access
+is allowed, then programs such as
+.BR talk (1)
+and
+.BR write (1)
+may display messages on the terminal.
+.PP
+Traditionally, write access is allowed by default.  However, as users
+become more conscious of various security risks, there is a trend to remove
+write access by default, at least for the primary login shell.  To make
+sure your ttys are set the way you want them to be set,
+.B mesg
+should be executed in your login scripts.
+.PP
+The
+.B mesg
+utility silently exits with error status 2 if the current standard error output does
+not refer to the terminal.  In this case execute
+.B mesg
+is pointless.  The command line option \fB\-\-verbose\fR forces
+mesg to print a warning in this situation.  This behaviour has been introduced
+in version 2.33.
+.SH ARGUMENTS
+.TP
+.B n
+Disallow messages.
+.TP
+.B y
+Allow messages to be displayed.
+.PP
+If no arguments are given,
+.B mesg
+shows the current message status on standard error output.
+.SH OPTIONS
+.TP
+.BR \-v , " \-\-verbose"
+Explain what is being done.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.SH EXIT STATUS
+The
+.B mesg
+utility exits with one of the following values:
+.RS 4
+.TP
+.B "\ 0"
+Messages are allowed.
+.TP
+.B "\ 1"
+Messages are not allowed.
+.TP
+.B ">1"
+An error has occurred.
+.RE
+.SH FILES
+.I /dev/[pt]ty[pq]?
+.SH "SEE ALSO"
+.BR login (1),
+.BR talk (1),
+.BR write (1),
+.BR wall (1),
+.BR xterm (1)
+.SH HISTORY
+A
+.B mesg
+command appeared in Version 6 AT&T UNIX.
+
+.SH AVAILABILITY
+The mesg command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.

+.TH SCRIPT "1" "June 2014" "util-linux" "User Commands"
+.SH NAME
+script \- make typescript of terminal session
+.SH SYNOPSIS
+.B script
+[options]
+.RI [ file ]
+.SH DESCRIPTION
+.B script
+makes a typescript of everything displayed on your terminal.  It is useful for
+students who need a hardcopy record of an interactive session as proof of an
+assignment, as the typescript file can be printed out later with
+.BR lpr (1).
+.PP
+If the argument
+.I file
+is given,
+.B script
+saves the dialogue in this
+.IR file .
+If no filename is given, the dialogue is saved in the file
+.BR typescript .
+.SH OPTIONS
+Below, the \fIsize\fR argument may be followed by the multiplicative
+suffixes KiB (=1024), MiB (=1024*1024), and so on for GiB, TiB, PiB, EiB, ZiB and YiB
+(the "iB" is optional, e.g. "K" has the same meaning as "KiB"), or the suffixes
+KB (=1000), MB (=1000*1000), and so on for GB, TB, PB, EB, ZB and YB.
+.TP
+\fB\-a\fR, \fB\-\-append\fR
+Append the output to
+.I file
+or to
+.BR typescript ,
+retaining the prior contents.
+.TP
+\fB\-c\fR, \fB\-\-command\fR \fIcommand\fR
+Run the
+.I command
+rather than an interactive shell.  This makes it easy for a script to capture
+the output of a program that behaves differently when its stdout is not a
+tty.
+.TP
+\fB\-e\fR, \fB\-\-return\fR
+Return the exit code of the child process.  Uses the same format as bash
+termination on signal termination exit code is 128+n.  The exit code of
+the child process is always stored in type script file too.
+.TP
+\fB\-f\fR, \fB\-\-flush\fR
+Flush output after each write.  This is nice for telecooperation: one person
+does `mkfifo foo; script -f foo', and another can supervise real-time what is
+being done using `cat foo'.
+.TP
+\fB\-\-force\fR
+Allow the default output destination, i.e. the typescript file, to be a hard
+or symbolic link.  The command will follow a symbolic link.
+.TP
+\fB\-o\fR, \fB\-\-output-limit\fR \fIsize\fR
+Limit the size of the typescript and timing files to
+.I size
+and stop the child process after this size is exceeded.  The calculated
+file size does not include the start and done messages that the
+.B script
+command prepends and appends to the child process output.
+Due to buffering, the resulting output file might be larger than the specified value.
+.TP
+\fB\-q\fR, \fB\-\-quiet\fR
+Be quiet (do not write start and done messages to standard output).
+.TP
+\fB\-t\fR[\fIfile\fR], \fB\-\-timing\fR[=\fIfile\fR]
+Output timing data to standard error, or to
+.I file
+when given.  This data contains two fields, separated by a space.  The first
+field indicates how much time elapsed since the previous output.  The second
+field indicates how many characters were output this time.  This information
+can be used to replay typescripts with realistic typing and output delays.
+.TP
+\fB\-V\fR, \fB\-\-version\fR
+Display version information and exit.
+.TP
+\fB\-h\fR, \fB\-\-help\fR
+Display help text and exit.
+.SH NOTES
+The script ends when the forked shell exits (a
+.I control-D
+for the Bourne shell
+.RB ( sh (1)),
+and
+.IR exit ,
+.I logout
+or
+.I control-d
+(if
+.I ignoreeof
+is not set) for the
+C-shell,
+.BR csh (1)).
+.PP
+Certain interactive commands, such as
+.BR vi (1),
+create garbage in the typescript file.
+.B script
+works best with commands that do not manipulate the screen, the results are
+meant to emulate a hardcopy terminal.
+.PP
+It is not recommended to run
+.B script
+in non-interactive shells.  The inner shell of
+.B script
+is always interactive, and this could lead to unexpected results.  If you use
+.B script
+in the shell initialization file, you have to avoid entering an infinite
+loop.  You can use for example the \fB\%.profile\fR file, which is read
+by login shells only:
+.RS
+.RE
+.sp
+.na
+.RS
+.nf
+if test -t 0 ; then
+    script
+    exit
+fi
+.fi
+.RE
+.ad
+.PP
+You should also avoid use of script in command pipes, as
+.B script
+can read more input than you would expect.
+.PP
+.SH ENVIRONMENT
+The following environment variable is utilized by
+.BR script :
+.TP
+.B SHELL
+If the variable
+.B SHELL
+exists, the shell forked by
+.B script
+will be that shell.  If
+.B SHELL
+is not set, the Bourne shell is assumed.  (Most shells set this variable
+automatically).
+.SH SEE ALSO
+.BR csh (1)
+(for the
+.I history
+mechanism),
+.BR scriptreplay (1)
+.SH HISTORY
+The
+.B script
+command appeared in 3.0BSD.
+.SH BUGS
+.B script
+places
+.I everything
+in the log file, including linefeeds and backspaces.  This is not what the
+naive user expects.
+.PP
+.B script
+is primarily designed for interactive terminal sessions.  When stdin
+is not a terminal (for example: \fBecho foo | script\fR), then the session
+can hang, because the interactive shell within the script session misses EOF and
+.B script
+has no clue when to close the session.  See the \fBNOTES\fR section for more information.
+.SH AVAILABILITY
+The script command is part of the util-linux package and is available from
+.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/
+Linux Kernel Archive
+.UE .

+.TH SCRIPTREPLAY 1 "September 2011" "util-linux" "User Commands"
+.SH "NAME"
+scriptreplay \- play back typescripts, using timing information
+.SH "SYNOPSIS"
+.B scriptreplay
+[options]
+.RB [ \-t ]
+.I timingfile
+.RI [ typescript
+.RI [ divisor ]]
+.SH "DESCRIPTION"
+This program replays a typescript, using timing information to ensure that
+output happens in the same rhythm as it originally appeared when the script
+was recorded.
+.PP
+The replay simply displays the information again; the programs
+that were run when the typescript was being recorded are not run again.
+Since the same information is simply being displayed,
+.B scriptreplay
+is only guaranteed to work properly if run on the same type of
+terminal the typescript was recorded on.  Otherwise, any escape characters
+in the typescript may be interpreted differently by the terminal to
+which
+.B scriptreplay
+is sending its output.
+.PP
+The timing information is what
+.BR script (1)
+outputs to standard error if it is
+run with the
+.B \-t
+parameter.
+.PP
+By default, the typescript to display is assumed to be named
+.BR typescript ,
+but other filenames may be specified, as the second parameter or with option
+.BR \-s .
+.PP
+If the third parameter is specified, it is used as a speed-up multiplier.
+For example, a speed-up of 2 makes
+.B scriptreplay
+go twice as fast, and a speed-up of 0.1 makes it go ten times slower
+than the original session.
+.SH OPTIONS
+The first three options will override old-style arguments.
+.TP
+.BR \-t , " \-\-timing " \fIfile\fR
+File containing \fBscript\fR's timing output.
+.TP
+.BR \-s , " \-\-typescript " \fIfile\fR
+File containing \fBscript\fR's terminal output.
+.TP
+.BR \-d , " \-\-divisor " \fInumber\fR
+Speed up the replay displaying this
+.I number
+of times.  The argument is a floating point number.  It's called divisor
+because it divides the timings by this factor.
+.TP
+.BR \-m , " \-\-maxdelay " \fInumber\fR
+Set the maximum delay between transcript updates to
+.I number
+of seconds.  The argument is a floating point number.  This can be used to
+avoid long pauses in the transcript replay.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.SH "EXAMPLE"
+.nf
+% script --timing=file.tm script.out
+Script started, file is script.out
+% ls
+<etc, etc>
+% exit
+Script done, file is script.out
+% scriptreplay --timing file.tm --typescript script.out

+.TH SETTERM 1 "May 2014" "util-linux" "User Commands"
+.SH NAME
+setterm \- set terminal attributes
+.SH SYNOPSIS
+.B setterm
+[options]
+.SH DESCRIPTION
+.B setterm
+writes to standard output a character string that will invoke the specified
+terminal capabilities.  Where possible
+.I terminfo
+is consulted to find the string to use.  Some options however (marked "virtual
+consoles only" below) do not correspond to a
+.BR terminfo (5)
+capability.  In this case, if the terminal type is "con" or "linux" the string
+that invokes the specified capabilities on the PC Minix virtual console driver
+is output.  Options that are not implemented by the terminal are ignored.
+.SH OPTIONS
+For boolean options
+.RB ( on " or " off ),
+the default is
+.BR on .
+.P
+Below, an
+.I 8-color
+can be
+.BR black ,
+.BR red ,
+.BR green ,
+.BR yellow ,
+.BR blue ,
+.BR magenta ,
+.BR cyan ,
+or
+.BR white .
+.P
+A
+.I 16-color
+can be an
+.IR 8-color ,
+or
+.BR grey ,
+or
+.B bright
+followed
+by
+.BR red ,
+.BR green ,
+.BR yellow ,
+.BR blue ,
+.BR magenta ,
+.BR cyan ,
+or
+.BR white .
+.P
+The various color options may be set independently, at least on virtual
+consoles, though the results of setting multiple modes (for example,
+.B \-\-underline
+and
+.BR \-\-half\-bright )
+are hardware-dependent.
+.TP
+\fB\-\-appcursorkeys\fP [\fBon\fP|\fBoff\fP]  (virtual consoles only)
+Sets Cursor Key Application Mode on or off.  When on, ESC O A, ESC O B, etc.
+will be sent for the cursor keys instead of ESC [ A, ESC [ B, etc.  See the
+.I vi and Cursor-Keys
+section of the
+.I Text-Terminal-HOWTO
+for how this can cause problems for \fBvi\fR users.
+.TP
+\fB\-\-append\fP [\fIconsole_number\fP]
+Like
+.BR \-\-dump ,
+but appends to the snapshot file instead of overwriting it.  Only works if no
+.B \-\-dump
+options are given.
+.TP
+\fB\-\-background\fP \fI8-color\fP|\fBdefault\fP
+Sets the background text color.
+.TP
+\fB\-\-blank\fP [\fB0-60\fP|\fBforce\fP|\fBpoke\fP]  (virtual consoles only)
+Sets the interval of inactivity, in minutes, after which the screen will be
+automatically blanked (using APM if available).  Without an argument, it gets
+the blank status (returns which vt was blanked, or zero for an unblanked vt).
+.IP
+The
+.B force
+option keeps the screen blank even if a key is pressed.
+.IP
+The
+.B poke
+option unblanks the screen.
+.TP
+\fB\-\-bfreq\fP [\fInumber\fP]  (virtual consoles only)
+Sets the bell frequency in Hertz.  Without an argument, it defaults to
+.BR 0 .
+.TP
+\fB\-\-blength\fP [\fB0-2000\fP]  (virtual consoles only)
+Sets the bell duration in milliseconds.  Without an argument, it defaults to
+.BR 0 .
+.TP
+.BR \-\-blink " [" on | off ]
+Turns blink mode on or off.  Except on a virtual console,
+.B \-\-blink off
+turns off all attributes (bold, half-brightness, blink, reverse).
+.TP
+.BR \-\-bold " [" on | off ]
+Turns bold (extra bright) mode on or off.  Except on a virtual console,
+.B \-\-bold off
+turns off all attributes (bold, half-brightness, blink, reverse).
+.TP
+\fB\-\-clear\fP [\fBall\fP|\fBrest\fP]
+Without an argument or with the argument
+.BR all ,
+the entire screen is cleared and the cursor is set to the home position,
+just like
+.BR clear (1)
+does.  With the argument
+.BR rest ,
+the screen is cleared from the current cursor position to the end.
+.TP
+\fB\-\-clrtabs\fP [\fItab1 tab2 tab3\fP ...]  (virtual consoles only)
+Clears tab stops from the given horizontal cursor positions, in the range
+.BR 1-160 .
+Without arguments, it clears all tab stops.
+.TP
+.BR \-\-cursor " [" on | off ]
+Turns the terminal's cursor on or off.
+.TP
+\fB\-\-default\fP
+Sets the terminal's rendering options to the default values.
+.TP
+\fB\-\-dump\fP [\fIconsole_number\fP]
+Writes a snapshot of the virtual console with the given number
+to the file specified with the
+.B \-\-file
+option, overwriting its contents; the default is
+.IR screen.dump .
+Without an argument, it dumps the current virtual console.  This overrides
+.BR \-\-append .
+.TP
+\fB\-\-file\fP \fIfilename\fP
+Sets the snapshot file name for any
+.B \-\-dump
+or
+.B \-\-append
+options on the same command line.  If this option is not present, the default
+is
+.I screen.dump
+in the current directory.  A path name that exceeds the system maximum will be
+truncated, see PATH_MAX from linux/limits.h for the value.
+.TP
+\fB\-\-foreground\fP \fI8-color\fP|\fBdefault\fP
+Sets the foreground text color.
+.TP
+.BR \-\-half\-bright " [" on | off ]
+Turns dim (half-brightness) mode on or off.  Except on a virtual console,
+.B \-\-half\-bright off
+turns off all attributes (bold, half-brightness, blink, reverse).
+.TP
+\fB\-\-hbcolor\fP \fI16-color\fP
+Sets the color for bold characters.
+.TP
+\fB\-\-initialize\fP
+Displays the terminal initialization string, which typically sets the
+terminal's rendering options, and other attributes to the default values.
+.TP
+.BR \-\-inversescreen " [" on | off ]
+Swaps foreground and background colors for the whole screen.
+.TP
+.BR \-\-linewrap " [" on | off ]
+Makes the terminal continue on a new line when a line is full.
+.TP
+.BR \-\-msg " [" on | off "]  (virtual consoles only)"
+Enables or disables the sending of kernel
+.BR printk ()
+messages to the console.
+.TP
+\fB\-\-msglevel\fP \fB0-8\fP  (virtual consoles only)
+Sets the console logging level for kernel
+.B printk()
+messages.  All messages strictly more important than this will be printed, so a
+logging level of
+.B 0
+has the same effect as
+.B \-\-msg on
+and a logging level of
+.B 8
+will print all kernel messages.
+.BR klogd (8)
+may be a more convenient interface to the logging of kernel messages.
+.TP
+\fB\-\-powerdown\fP [\fB0-60\fP]
+Sets the VESA powerdown interval in minutes.  Without an argument, it defaults
+to
+.B 0
+(disable powerdown).  If the console is blanked or the monitor is in suspend
+mode, then the monitor will go into vsync suspend mode or powerdown mode
+respectively after this period of time has elapsed.
+.TP
+\fB\-\-powersave\fP \fBoff\fP
+Turns off monitor VESA powersaving features.
+.TP
+\fB\-\-powersave\fP \fBon\fP|\fBvsync\fP
+Puts the monitor into VESA vsync suspend mode.
+.TP
+\fB\-\-powersave\fP \fBpowerdown\fP
+Puts the monitor into VESA powerdown mode.
+.TP
+\fB\-\-powersave\fP \fBhsync\fP
+Puts the monitor into VESA hsync suspend mode.
+.TP
+\fB\-\-regtabs\fP [\fB1-160\fP]  (virtual consoles only)
+Clears all tab stops, then sets a regular tab stop pattern, with one tab every
+specified number of positions.  Without an argument, it defaults to
+.BR 8 .
+.TP
+.BR \-\-repeat " [" on | off "]  (virtual consoles only)"
+Turns keyboard repeat on or off.
+.TP
+\fB\-\-reset\fP
+Displays the terminal reset string, which typically resets the terminal to
+its power-on state.
+.TP
+\fB\-\-resize\fP
+Reset terminal size by assessing maximum row and column.  This is useful
+when actual geometry and kernel terminal driver are not in sync.  Most
+notable use case is with serial consoles, that do not use
+.BR ioctl (3)
+but just byte streams and breaks.
+.TP
+\fB\-\-reverse\fP [\fBon\fP|\fBoff\fP]
+Turns reverse video mode on or off.  Except on a virtual console,
+.B \-\-reverse off
+turns off all attributes (bold, half-brightness, blink, reverse).
+.TP
+\fB\-\-store\fP  (virtual consoles only)
+Stores the terminal's current rendering options (foreground and background
+colors) as the values to be used at reset-to-default.
+.TP
+\fB\-\-tabs\fP [\fItab1 tab2 tab3\fP ...]
+Sets tab stops at the given horizontal cursor positions, in the range
+.BR 1-160 .
+Without arguments, it shows the current tab stop settings.

+\fB\-\-version\fP
+Displays version information and exits.
+.TP
+\fB\-\-help\fP
+Displays a help text and exits.
+.SH COMPATIBILITY
+Since version 2.25
+.B setterm
+has support for long options with two hyphens, for example
+.BR \-\-help ,
+beside the historical long options with a single hyphen, for example
+.BR \-help .
+In scripts it is better to use the backward-compatible single hyphen
+rather than the double hyphen.  Currently there are no plans nor good
+reasons to discontinue single-hyphen compatibility.
+.SH "SEE ALSO"
+.BR stty (1),
+.BR tput (1),
+.BR tty (4),
+.BR terminfo (5)
+.SH BUGS
+Differences between the Minix and Linux versions are not documented.
+.SH AVAILABILITY
+The setterm command is part of the util-linux package and is available from
+.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/
+Linux Kernel Archive
+.UE .

+ * Semantics:
+ *
+ * Setterm writes to standard output a character string that will
+ * invoke the specified terminal capabilities.  Where possible
+ * terminfo is consulted to find the string to use.  Some options
+ * however do not correspond to a terminfo capability.  In this case if
+ * the terminal type is "con*", or "linux*" the string that invokes
+ * the specified capabilities on the PC Linux virtual console driver
+ * is output.  Options that are not implemented by the terminal are
+ * ignored.
+ *
+ * The following options are non-obvious.
+ *
+ *   -term can be used to override the TERM environment variable.
+ *
+ *   -reset displays the terminal reset string, which typically resets the
+ *      terminal to its power on state.
+ *
+ *   -initialize displays the terminal initialization string, which typically
+ *      sets the terminal's rendering options, and other attributes to the
+ *      default values.
+ *
+ *   -default sets the terminal's rendering options to the default values.
+ *
+ *   -store stores the terminal's current rendering options as the default
+ *      values.  */

+.TH WALL "1" "August 2013" "util-linux" "User Commands"
+.SH NAME
+wall \- write a message to all users
+.SH SYNOPSIS
+.B wall
+.RB [ \-n ]
+.RB [ \-t
+.IR timeout ]
+.RB [ \-g
+.IR group ]
+.RI [ message " | " file ]
+.SH DESCRIPTION
+.B wall
+displays a
+.IR message ,
+or the contents of a
+.IR file ,
+or otherwise its standard input, on the terminals of all currently logged
+in users.  The command will wrap lines that are longer than 79 characters.
+Short lines are whitespace padded to have 79 characters.  The command will
+always put a carriage return and new line at the end of each line.
+.PP
+Only the superuser can write on the terminals of users who have chosen to
+deny messages or are using a program which automatically denies messages.
+.PP
+Reading from a
+.I file
+is refused when the invoker is not superuser and the program is
+set-user-ID or set-group-ID.
+.SH OPTIONS
+.TP
+.BR \-n , " \-\-nobanner"
+Suppress the banner.
+.TP
+.BR \-t , " \-\-timeout " \fItimeout\fR
+Abandon the write attempt to the terminals after \fItimeout\fR seconds.
+This \fItimeout\fR must be a positive integer.  The default value
+is 300 seconds, which is a legacy from the time when people ran terminals over
+modem lines.
+.TP
+.BR \-g , " \-\-group " \fIgroup\fR
+Limit printing message to members of group defined as a
+.I group
+argument.  The argument can be group name or GID.
+.TP
+.BR \-V , " \-\-version"
+Display version information and exit.
+.TP
+.BR \-h , " \-\-help"
+Display help text and exit.
+.SH NOTES
+Some sessions, such as wdm, that have in the beginning of
+.BR utmp (5)
+ut_type data a ':' character will not get the message from
+.BR wall .
+This is done to avoid write errors.
+.SH SEE ALSO
+.BR mesg (1),
+.BR talk (1),
+.BR write (1),
+.BR shutdown (8)
+.SH HISTORY
+A
+.B wall
+command appeared in Version 7 AT&T UNIX.
+.SH AVAILABILITY
+The wall command is part of the util-linux package and is available from
+.UR https://\:www.kernel.org\:/pub\:/linux\:/utils\:/util-linux/
+Linux Kernel Archive
+.UE .

+.TH WRITE 1 "March 1995" "util-linux" "User Commands"
+.SH NAME
+write \- send a message to another user
+.SH SYNOPSIS
+.B write
+.I user
+.RI [ ttyname ]
+.SH DESCRIPTION
+.B write
+allows you to communicate with other users, by copying lines from
+your terminal to theirs.
+.PP
+When you run the
+.B write
+command, the user you are writing to gets a message of the form:
+.PP
+.RS
+Message from yourname@yourhost on yourtty at hh:mm ...
+.RE
+.PP
+Any further lines you enter will be copied to the specified user's
+terminal.  If the other user wants to reply, they must run
+.B write
+as well.
+.PP
+When you are done, type an end-of-file or interrupt character.  The other
+user will see the message
+.B EOF
+indicating that the conversation is over.
+.PP
+You can prevent people (other than the superuser) from writing to you with
+the
+.BR mesg (1)
+command.  Some commands, for example
+.BR nroff (1)
+and
+.BR pr (1),
+may automatically disallow writing, so that the output they produce
+isn't overwritten.
+.PP
+If the user you want to write to is logged in on more than one terminal,
+you can specify which terminal to write to by giving the terminal
+name as the second operand to the
+.B write
+command.  Alternatively, you can let
+.B write
+select one of the terminals \- it will pick the one with the shortest idle
+time.  This is so that if the user is logged in at work and also dialed up
+from home, the message will go to the right place.
+.PP
+The traditional protocol for writing to someone is that the string `\-o',
+either at the end of a line or on a line by itself, means that it's the
+other person's turn to talk.  The string `oo' means that the person
+believes the conversation to be over.
+.SH "SEE ALSO"
+.BR mesg (1),
+.BR talk (1),
+.BR who (1)
+.SH HISTORY
+A
+.B write
+command appeared in Version 6 AT&T UNIX.
+.SH AVAILABILITY
+The write command is part of the util-linux package and is available from
+https://www.kernel.org/pub/linux/utils/util-linux/.
