Richard (richlowe) and a few other people from #fu were talking about being able to do things like cdup 5 to jump up 5 directories. I thought it would be nicer if my existing .. alias took an optional argument to do the same thing. Here's the result (for bash):
function cdup() {
if [ "x$1" = "x" ]; then max=1; else max=$1; fi
for ((i=0; i<$max; i++)); do cd ..; done
}
alias ..="cdup";
So .. works the same as it did before, but now you can do stuff like this:
pabs@vault:/usr/local/share/raggle/themes> .. pabs@vault:/usr/local/share/raggle> .. 2 pabs@vault:/usr/local>
Richard's version does the same thing for zsh.
