How to use script and scriptfix

What script does

The script program intercepts communication between the shell (the program that prints the “%” signs) and the keyboard and terminal window, and duplicates it and copies it to a file.

To use script

• Type
  script scriptfilename
  to begin capturing information in a script file.
• Do what you would normally do.
• Type control-D to quit the script session.

What scriptfix does

The scriptfix removes control codes (like backspace characters, and instructions that cause inverse video) from the scriptfile.

This is necessary because script just splits the program output in two. Information that is useful to the terminal window is not useful in the scriptfile.
