perldoc -q environment

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?

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 its own 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.
