14.8. Tips on Using Command History
What are some other ways I can use command
history?
If you type history, a numbered list
scrolls 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 are displayed (you can use any
quantity as an argument of the history command).
14.8.1. 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) executes the command which is numbered
302 in the history file.
"Bang string": Typing
!string (as in
!rpm) executes 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 moves 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.
