tiding up the PATH

I have previously noticed that loading up the list of application available in $PATH took a long time in [wmii-lua]{tag/wmiirc-lua}. I recently found out that it was related to me having multiple duplicates in my [zsh]{tag/zsh} environment.

To clean this up I added the following to my zsh configuration:

    typeset -U path cdpath manpath fpath

This removes duplicates from the PATH, CDPATH, MANPATH, and FPATH environment variables.

Well, technically it removes duplicates from the path, cdpath, manpath, and fpath arrays; but these are treated special and updating them automatically generates their respective :-delimited environment variables.

Zsh rocks!
