( #3333=superdoc: print w/ replies, xml ) Need Help??

Take a look at the documentation for the -p and -n switches in perlrun. In prasee er...short, it says

-p causes Perl to assume the following loop around your program, which ma +kes it iterate over filename arguments somewhat like sed: LINE:while (<>) { # your program goes here } continue { print or die "-p destination: $!\n"; }

If you substitute the 'program' eg. "}{die" where the comment above says " your program goes here", then you willl see how the thing works.


Examine what is said, not who speaks.

The 7th Rule of perl club is -- pearl clubs are easily damaged. Use a diamond club instead.
