What are your favorite BASH aliases?

[pw_f100_220]

Just curious if anyone came up with any fun ones as well as downright ingenious. I mostly use Fluxbox so i use xrandr to work with dual monitors on my laptop:

alias mirror='xrandr --output LVDS --auto --output VGA --auto --same-as LVDS'
alias right='xrandr --output VGA --auto --right-of LVDS'
alias left='xrandr --output VGA --auto --left-of LVDS'

One I'm not quite as proud of, but in my earliest days of Ubuntu, I looked forever for the command to delete directories only to find it's an option of rm...so I named the alias to reflect my frustration:

alias ****='rm -rf'

It really is rather poetic when deleting a bad movie...~$ **** Hitman

:)

alias ..='cd ..'
alias ~='cd ~'
alias ?='man'
alias !='sudo'
alias +='pager'
alias open='xdg-open'
alias browser='x-www-browser'
alias edit='gedit'
alias apt='sudo aptitude'
alias todo='grep -n TODO *.*'

Reviving old thread because I' always interested in adding extra stuff to my aliases files.

I've been using zsh for quite a while now. I like not having to use the cd command to switch directories. Still I fire up Bash every now and again and my aliases files for both zsh and bash are largely similar, so I'll post it here.
