Re: directory alias

I make variables for directories I use a lot

db="$HOME/Dropbox"

bin="$db/bin"

and then I can use that to either move files (mv foo $bin) or 'cd' to them
just by typing the variable "$db" and hitting enter.

But if that's what you mean by a "universal alias", then you'd have to do
something else.

You could make your own `cd` function

function cd {

if [ "$#" = "0" ]
then
# if no arg, go to $HOME
 chdir "$HOME"
else
 if [ -d "$@" ]
then
# if the arg is a valid directory, go there
 chdir "$@"
else
case "$@" in
 bar)
chdir  /usr/local/some/path/bar
;;

foo)
chdir ~/some/deep/directory/tree/foo

;;
 *)
echo "chdir: no such file or directory: $@"
 return 1
;;
esac
 fi
fi
}
