tipstricks

I just came back from this years FROSCON event and even though i don't think that i did discover any new big things there were two small tools that i wasn't aware of so far which i'll probably use on a rather regular basis in the future.

Has this ever happened to you? (i bet it has):

  $ export PATH=$PAHT:/usr/local/foo/bin
  $ ls
  ls: command not found

It is so easy to have a typo in that PATH assignment, and so hard to recover from it (esp. when not using X11).
