  I'm no UNIX guru, but I've encountered a similar condition, and a
rather simple workaround which is likely to also apply to your case.

  My *speculation* is that when you type "firstprog", the shell
(bash, in your case) pulls up the environment variable that specifies
common execution paths, and looks in each path in turn for an
executable by that name -- and doesn't find one.
  The workaround is to type "./firstprog"; since this specifies "in
the current directory", the shell is not allowed to go looking in the
various path folders.  It looks only where it has been told, and
succeeds.

  This suggests that a longer-term fix might be to modify the user
profile to include "." in the execution path -- but I'm fairly
certain there is some reason why this is not the default profile
setting.  That's getting beyond what I've needed to know for the
little bit of UNIX I use.
