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!
