uniq(1) expects sort(1)ed output, you also could use "sort -u",
but usually that's really not what you want...

Sometimes it's even rather attractive not to fork several time, but
to use only built-in stuff for reasons of speed or alike.  Especially,
if you are changing a lot in the environment, probably depending on
the platform (in NFS).
