Aliases

Going into bash, aliases make my life easier, really!
I kept adding these aliases in wherever .bashrc I have

someone@somewhere:~$ alias
alias acs='apt-cache search'
alias acso='apt-cache show'
alias dusk='du -s -k -c * | sort -rn'
alias greph='history | grep '
alias ls='ls --color=auto'
alias nsl='netstat -alnp --protocol=inet | grep -v CLOSE_WAIT | cut -c-6,21-94
| tail +2'
alias sadug='sudo apt-get dist-upgrade'
alias sapi='sudo apt-get install'
alias sapu='sudo apt-get update'
alias sapup='sudo apt-get upgrade'
someone@somewhere:~$

As you can see... it's very ubuntu, right? :-)
I think I need to add some more...
Any idea ?
