in reply to Pod Usage
Is this what you are looking for ?
if ($target !~ /..../) { print "Syntax Error: Target should be x or y or z\n"; pod2usage(-verbose => 1); # just the usage exit; }
Update
BTW, as I see you are a perl@newbie are you using strict and warnings in your script? If not have a look at Use strict warnings and diagnostics or die to see why it is a good idea.Cheers,
R.
