Christopher,
I appended a new directory name to my existing PATH:
/usr/local/bin:/bin:/usr/bin:/usr/X11R6/bin
using this command:
export PATH="$PATH:/home/leverett/bin"
this added "/home/leverett/bin" to the list of directories in PATH. Now
I can start C programs I write from any directory. Yes!!! I'm posting
this information in case somebody else asks this question later. I found
the Linux command in: "Red Hat LINUX secrets, 2nd edition" by Naba
Barkakati, 1998 publishers IDG Books,
895 pgs. I find myself reading any Linux information I can get my eyes
on...
thanks,
