hdb's point was your code boils down to `'patch-5.1.1.21510' =~ /patch-5.1.1.21510.gpg/;`, which is backwards from what you need. The behavior you seek would look more like `my @array = split('\n',$output); if ( grep { 'patch-5.1.1.21510.gpg' =~ /\Q$_\E/ } @array ) { print "Match found\n"; }` [download] Though, as implemented, you'd have problems because of whitespace. For this case, you'd probably be better off using index. #11929 First ask yourself `How would I do this without a computer?' Then have the computer do it the same way.	[reply] [d/l] [select]

But your explanation was the other way round. plz try to show us a reproducible code example instead of wording. Cheers Rolf ( addicted to the Perl Programming Language)	[reply]

Sorry about the confusion, the following is the code I have been trying `my $str = "update patch-5.1.1.21510"; my $patch = "patch-5.1.1.21510.gpg"; if ($str =~/$patch/ms) { print "Yes \n"; }` [download]	[reply] [d/l]

thats the way it works `DB<105> $str = "update\npatch-5.1.1.21510.pgp"; => "update\npatch-5.1.1.21510.pgp" DB<106> $patch = "patch-5.1.1.21510" => "patch-5.1.1.21510" DB<107> $str =~/\Q$patch/ => 1` [download] $patch must be included in $str not vice versa. No need for multiline because your pattern doesn't span multiple lines. '\Q' assures that regex syntax like '.' is escaped. Cheers Rolf ( addicted to the Perl Programming Language)	[reply] [d/l]

Along the lines of your initial code: `use strict; use warnings; my $PatchPath = "patch-5.1.1.21510.gpg"; my $output = "update patch-5.1.1.21510"; my @array = split /\s+/, $output; if ( grep { $PatchPath =~ /$_/ } @array ) { print "Match found\n"; }` [download] SORRY: This post is somehow to far up in the chain.
