Use "execvp". The "p" stands not only for pathname search, but also
will invoke a shell if the supplied program is in reality a script.
Eventually you may want to set PATH with `putenv' to make execvp
search the desired directories (only).

Small flame concerning choice of groups: How about a *first* try
with comp.unix.questions - you can have allways a second try with
c.u.w, but experience shows you may well receive the attention
of a wizard in c.u.q. At most make a crosspost but leave followups
to c.u.q. I felt tempted to redirect followups, but as I don't
appreciate to have threads pop up "out of nothing" I left it here.
