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
          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.

   -q, --quiet
          Be quiet (do  not  write  start  and  done  messages  to  either
          standard output or the typescript file).

   -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
          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
   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.


   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
   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.


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