I have written a filter in C to (un)"fix" a path. When a $path or $PATH
shell variable is piped through it, it will meticulously remove the "."
that annoys some of us very much (and lots of other garbage). I hope
you will find it useful.
You can find it at http://workstation.mc.yale.edu/pub/
The source, executable, Makefile, README, etc. is all there.
It should be pretty self-explanatory.
For those of you who care, this program likely took me more time than my
CS 223 assignment, and that is even when I actually built this program
by using modified components from my CS 223 assignment C2html.
As always, comments and suggestions are highly welcome.
