Along similar lines, I have this one-liner as ~/bin/pmv: #! /bin/sh perl -m$1 -le 'print '$1'->VERSION || die "No VERSION in '$1'\n"' > I think that calling ->VERSION is more correct. So do I. In fact I used to use $VERSION in my script, but changed to ->VERSION after some situation in which it worked and $VERSION didn't. Sorry, I can't right now remember what that was. Smylers
