Shortcuts with hash -d in zsh

I stumbled across this zsh tricks post yesterday and am blown away by the hash command, which allows you to see and manipulate the hash table for either commands or for directory shortcuts.

hash by itself in zsh will output the location for all the commands.

hash -d shows you all of the named directories, and check this out you can navigate to one of those directories with ~shortcutname, like this:

$ hash -d | grep bin
bin=/bin
daemon=/usr/sbin
proxy=/bin
sync=/bin
$ cd ~daemon
$ pwd
/usr/sbin

You can create your own directory shortcuts like this:

$ hash -d mydir=/home/me/very/long/path

And then cd to it:

$ cd ~mydir
$ pwd
/home/me/very/long/path

Crazy! Read more in the zsh docs.
