       script - make typescript of terminal session

       script [options] [file]

       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 typescript.

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

       -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 telecoopera-
              tion: 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  sym-
              bolic link.

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

       -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.

       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  manipu-
       late the screen, the results are meant to emulate a hardcopy terminal.

       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.

       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).

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

       The script command appeared in 3.0BSD.

       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 ses-
       sion  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.

       The  script  command is part of the util-linux package and is available
       from Linux Kernel Archive <
