NAME         top

       script - make typescript of terminal session

SYNOPSIS         top

       script [options] [file]

DESCRIPTION         top

       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 lpr(1).

       If the argument file is given, script saves the dialogue in this
       file.  If no filename is given, the dialogue is saved in the file

OPTIONS         top

       Below, the size 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.

       -a, --append
              Append the output to file or to 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.  The exit code of the child process is always stored in
              type script file too.

       -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'.

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

       -o, --output-limit size
              Limit the size of the typescript and timing files to 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 script command prepends and appends to the
              child process output.  Due to buffering, the resulting output
              file might be larger than the specified value.

       -q, --quiet
              Be quiet (do not write start and done messages to standard

       -t[file], --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
              Display version information and exit.

       -h, --help
              Display help text and exit.

NOTES         top

       The script ends when the forked shell exits (a control-D for 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

       It is not recommended to run script in non-interactive shells.  The
       inner shell of script is always interactive, and this could lead to
       unexpected results.  If you use script in the shell initialization
       file, you have to avoid entering an infinite loop.  You can use for
       example the .profile file, which is read by login shells only:

              if test -t 0 ; then

       You  should  also avoid use of script in command pipes, as script can
       read more input than you would expect.

ENVIRONMENT         top

       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).

HISTORY         top

       The script command appeared in 3.0BSD.

BUGS         top

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

       script is primarily designed for interactive terminal sessions.  When
       stdin is not a terminal (for example: echo foo | script), then the
       session can hang, because the interactive shell within the script
       session misses EOF and script has no clue when to close the session.
       See the NOTES section for more information.
