Generally you should be exceedingly careful about putting '.' onto
your $PATH. You should certainly not put '.' into root's $PATH, and
preferably not at the beginning of the $PATH for ordinary users.
ie. If you must put '.' in your path, do it like this:
PATH=${PATH}:. ; export PATH
or
setenv PATH ${PATH}:.
The danger with having '.' on a the $PATH is that you can trick
(deliberately or not) people into running trojan programs. Bad for
ordinary users, disasterous for root.
Cheers,
Matthew
