* This is another very handy tool for saving typing
* Previous commands you have used are stored in your "history".
* You use the up and down arrow keys to travel through all the command you can used previously.
* The command itself, <code>history</code>will return a list of the last 15 commands run.
* Going back sequentially can be a bit tedious, <code>ctrl+r</code> will accept hints from you and try to find the past comman that most ressembles your hints.

== Exercise ==
* Try
history -3
ctrl+r kir

* Are you seeing what you are expecting?

which most of the time is visible in the line above.

* <code>!$<RET></code>: the final argument of the last command
* <code>!!<RET></code>: the entire last command
* <code>!:1-$<RET></code>: everthing except the first word of the last command
* <code>!$<RET></code>: the final argument of the last command
* <code>^then^now<RET></code>: replace the first occurence of then in last command with now
* <code>!!:gs/then/now<RET></code>: replace the ALL occurences of "then" in last command with "now"
