script - make typescript of terminal session SYNOPSIS
Script makes a typescript of everything printed on your ter- minal. 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 all dialogue in file. If no file name is given, the typescript is saved in the file typescript.
, retaining the prior contents.
Flush output after each write. This is nice for tele- cooperation: One person does `mkfifo foo; script -f foo' and another can supervise real-time what is being done using `cat foo'.
Output timeing data to standard error. This data con- tains two fields, separated by a space. The first field indicates how much time elapsed since the pre- vious 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.
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 terminal.
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 vari- able automatically).

Script places everything in the log file, including line- feeds and backspaces. This is not what the naive user expects.
