in reply to search for a pattern in file without opening the file

Unfortunately, perl is completely missing the 'Telepathy::File' module, last I checked, and will thus need to actually open files to read them, just like every other computer program would.

What do you need to put in another array for post processing? The filename? Maybe something like this:

my @files = grep { open my $fh, '<', $_ or die "Failed to open $_: $!"; my $rc = 0; my $l; while (!$rc && defined($l = <$fh>)) { $rc++ if $l =~ /^source/; } $rc } @arr1;
(Untested.) Maybe. Hard to tell without more info from you.
