16.6. Tips on Using Command History
What are some other ways I can use command
history?
If you type history, you will see a
numbered list scroll by very quickly, showing you the previous 500
commands you have used.
You probably do not need to see all of the last 500 commands, so
the command history 20 might be useful. This
way, only the previous 20 commands you typed will display (you can use
any quantity as an argument of the history
command).
16.6.1. Other Shortcuts
Here are other command history shortcuts which may be useful to you:
"Bang, bang": Typing !! (called "bang bang")
executes the last command in the history.
"Bang number": Typing
!number (as in
!302) will execute the command which is
numbered 302 in the history file.
"Bang string": Typing
!string (as in
!rpm) will execute a command with the most recent
matching string from the history file.
[Up arrow] and [down arrow]:
At the shell or GUI terminal prompt, you can press the up arrow
to move back through previous commands in your history list (the
down arrow will move you forward through the commands) until you
find the command you want. Press [Enter] to
execute the command, just as if you had typed it on the command
line.
