Bash Tip

Try this:
> ls -al
drwxr-xr-x 23 steve steve 782 Dec 9 00:27 .
drwxr-xr-x 39 steve steve 1326 Dec 11 21:21
drwxr-xr-x 11 steve steve 374 Dec 11 18:16 .svn
.......
> !!
drwxr-xr-x 23 steve steve 782 Dec 9 00:27 .
drwxr-xr-x 39 steve steve 1326 Dec 11 21:21
drwxr-xr-x 11 steve steve 374 Dec 11 18:16 .svn
.......
> ls -al
drwxr-xr-x 23 steve steve 782 Dec 9 00:27 .
drwxr-xr-x 39 steve steve 1326 Dec 11 21:21
drwxr-xr-x 11 steve steve 374 Dec 11 18:16 .svn
.......
> ls !$
drwxr-xr-x 23 steve steve 782 Dec 9 00:27 .
drwxr-xr-x 39 steve steve 1326 Dec 11 21:21
drwxr-xr-x 11 steve steve 374 Dec 11 18:16 .svn
.......
So:
- !! reruns the last command (very useful if you forget to put sudo in front: > sudo !!).
- !$ gets the first param of the last command.
