     script - make typescript of terminal session

     script [-a] [-c COMMAND] [-f] [-q] [-t] [file]

     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

     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.


     -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 timing data to standard error. 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 typ-
             ing 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 com-
     mands that do not manipulate the screen, the results are meant to emulate a hardcopy terminal.

     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

     The script command is part of the util-linux-ng package and is available from ftp://ftp.ker-
