SUPERSCRIPT(1)

NAME
superscript - make typescript of terminal session

SYNOPSIS
superscript [-a] [file] [-p command] [-s] [-c command ...]

DESCRIPTION
superscript 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 lpr(1).

If the argument file is given, superscript saves all dialogue in file. If no file name is given, the typescript is saved in the file typescript.

The options are as follows:

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

-p command
    Send the output to a pipe running command.

-s  Be silent, do not display the usual start-up and end messages.

-c command ...
    Execute the remaining arguments instead of the default shell.

The script ends when the forked shell exits (a control-D (‘^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)). superscript will exit with the status of 0 unless any of its child processes fail. In which case, superscript will return 1.

Certain interactive commands, such as vi(1), create garbage in the typescript file. superscript works best with commands that do not manipulate the screen; the results are meant to emulate a hardcopy terminal.

ENVIRONMENT

SHELL
    Name of the shell to be forked by script. If not set, the Bourne shell is assumed. (Most shells set this variable automatically.)

HISTORY
The script command appeared in 3.0BSD.

superscript is an extended version of this command, with non-POSIX options.

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