• Standard UNIX, allows you to get previous commands without typing the whole line in.

  Two techniques

  1. Command completion
     Say the most recent thing you did that began with the letter a was
     appletviewer myStuff.html
     Then in UNIX, if you type
     r a
     It will execute again (repeat) appletviewer myStuff.html
     

     Say the most recent thing you did that began with the letter p was
     pico myStuff.html
     Then in UNIX, if you type
     r p
     It will execute again (repeat) pico myStuff.html

     Etc., etc, etc

  2. History access
     
     To go through your "history" of commands, (this way you are sure that the right command will be executed since it will not execute until you see the command and hit return)
     • esc k goes back (previous) - puts on the command line the most recent command. If you do it again, it gives the command before that, etc.
     • esc j goes forward (next) - it gives the command after the one showing currently. If you do it again, it gives the command after that, etc. When you are at the end of your History, it beeps
