       I {changed directory, modified my environment} in a perl
       script.  How come the change disappeared when I exited the
       script?  How do I get my changes to be visible?

               Unix
                   In the strictest sense, it can't be done--the
                   script executes as a different process from
                   the shell it was started from.  Changes to a
                   process are not reflected in its parent--only
                   in any children created after the change.
                   There is shell magic that may allow you to
                   fake it by eval()ing the script's output in
                   your shell; check out the comp.unix.questions
                   FAQ for details.
