How to Use the UNIX "script" Program

• The UNIX prompt is indicated by a greater-than sign: ">"
• CAPITAL LETTERS are used to indicate a filename that you choose.
• User input is in bold font

To make a transcript of an interaction on UNIX, do the following:

1. Type:
   > script FILENAME

   You will see the message:

   Script started, file is FILENAME

2. You are now in the "script" program, but it will look as if nothing else has happened. In particular, you will see your UNIX prompt.

3. At that prompt, enter whatever it is you wish to have a transcript of.

   E.g., to get a transcript of a SNePS interaction, you would need to invoke ACL Common Lisp, then invoke SNePS, then have some kind of interaction with SNePS, then exit SNePS, then exit Lisp. Simply type all the appropriate commands as if you were talking directly to UNIX:

   Script started, file is FILENAME
   > acl

4. You have now finished your interaction and are back at the UNIX prompt within the "script" program. Now you need to exit from "script". To do that, type "exit" at the prompt, and your real UNIX prompt will be returned to you:
   > exit
   exit
   Script done, file is FILENAME
   >

5. You are now back talking directly to UNIX. The next thing you need to do is print your transcript. However, you must first edit out all control characters from the file FILENAME. To do that, enter your favorite text editor with the file FILENAME, delete all control characters (normally, these will be a few occurrences of "^H", "^G", and lots of "^M").

6. Finally, send your file to the printer, using your favorite print command.
   • If your file is very long, you might want to use "fold" (to make sure long lines are not truncated) and "mpage" (to put two pages on one side) to print it:
     > fold FILENAME | mpage -2 | lpr

     The "lpr" command may need a -P argument containing the name of your favorite printer, e.g., lpr -Pgroucho_d
