Makes a typescript of a terminal session.
script [ -a ] [ File ]
The script command makes a typescript of everything displayed on your terminal. The typescript is written to the file specified by the File parameter. The typescript can later be sent to the line printer. If no file name is given, the typescript is saved in the current directory with the file name typescript.
The script ends when the forked shell exits.
This command is useful for producing hardcopy records when hardcopy terminals are in short supply. For example, use the script command when you are working on a CRT display and need a hardcopy record of the dialog.
