SCRIPT(1)							   User Commands							 SCRIPT(1)

NAME

       script - make typescript of terminal session

SYNOPSIS

       script [options] [file]

DESCRIPTION

       script  makes  a typescript of everything printed 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 lpr(1).

       If the argument file is given, script saves all dialogue in file.  If no file name is given, the typescript is  saved  in  the  file  type-
       script.

OPTIONS

       -a, --append
	      Append the output to file or typescript, retaining the prior contents.

       -c, --command command
	      Run  the	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.

       -e, --return
	      Return the exit code of the child process.  Uses the same format as bash termination on signal termination exit code is 128+n.

       -f, --flush
	      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'.

       --force
	      Allow  the  default output destination, i.e. the typescript file, to be a hard or symbolic link.	The command will follow a symbolic
	      link.

       -q, --quiet
	      Be quiet.

       -t, --timing[=file]
	      Output timing data to standard error, or to 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.

       -V, --version
	      Output version information and exit.

       -h, --help
	      Output help and exit.

NOTES

       The script ends when the forked shell exits (a control-D to exit the Bourne shell (sh(1)), and exit, logout or control-d (if  ignoreeof	is
       not set) for the C-shell, csh(1)).

       Certain interactive commands, such as vi(1), create garbage in the typescript file.  Script works best with commands that do not manipulate
       the screen, the results are meant to emulate a hardcopy terminal.

ENVIRONMENT

       The following environment variable is utilized by script:

       SHELL  If the variable SHELL exists, the shell forked by script will be that shell. If SHELL is not  set,  the  Bourne  shell  is  assumed.
	      (Most shells set this variable automatically).

SEE ALSO

       csh(1) (for the history mechanism), scriptreplay(1).

HISTORY

       The script command appeared in 3.0BSD.

BUGS

       Script places everything in the log file, including linefeeds and backspaces.  This is not what the naive user expects.

AVAILABILITY

       The script command is part of the util-linux package and is available from Linux Kernel Archive <ftp://ftp.kernel.org/pub/linux/utils/util-
       linux/>.
