in reply to Exiting a loop trickery

I think you're looking for last:

#!/usr/bin/perl -w use strict; while (<DATA>) { next unless /trigger/; while (<DATA>) { if ( $_ =~ /timestamp/ ) { print "Found timestamp\n"; last; } } } __DATA__ bar baz trigger qux timestamp quux quuux trigger quuuux timestamp bar

    Or, to avoid nesting loops, use a range operator:
    while (<DATA>) { if (/trigger/ .. /timestamp/) { if ( $_ =~ /timestamp/ ) { print "Found timestamp\n"; last; } } }

    Yes... "last", that is it.
    I even dug through my old book... I can't believe I overlooked it. What a rookie error!
