SCRIPT(1)                 BSD General Commands Manual                SCRIPT(1)

NAME
     script - make typescript of terminal session

SYNOPSIS
     script [-a] [-c COMMAND] [-f] [-q] [-t] [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 assign-
     ment, 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 typescript.

     Options:

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

     -c 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.

     -f      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’.

     -q      Be quiet.

     -t      Output timeing data to standard error. This data contains two fields, sepa-
             rated 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.

     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 vari-
            able 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.
