Thanks for the links i will check it out! Also i wasn't aware of the
-F function, playing with it now and that is a big help with working
around the whole color bit. Clearly the / is for directories. How are
the rest used? Surprisingly even google doesn't know. From what i
could see they didn't label links and such so not very helpful in that
respect but at least i wont try to vi a directory or cd to a file.
