Re^3: Need RegExp help - doing an AND match

See perlre.

/./ will match the character '.', but will also match many other characters. What you likely want is to quote the dot, so it loses its special meaning:

"." =~ m!\.!

Update: GrandFather spotted a missing ! at the end of the regular expression

Yes, I know what you mean but I'm not matching explicit text - here is an example: `@words = ("filename" , "file.txt"); $line = "my file is file.txt";` [download] I want to search this line and save it in a variable for later. These work assuming no lines contain both words: `$file = (grep{$line =~ /$_/i} @words)[0]; or foreach (@words) { next if($line !~ /$_/i); $file = $_; }` [download] So both work ($file is nonempty) but not good. Problem is that I will need to pass a variable into my RegExp for my search - which may or may not contain a "."	[reply] [d/l] [select]

You seemed to have missed the quoting of dot part in Corion's reply. In any case, refer to the `quotemeta` function description, usage of which would be something like ... `my @words = map { quotemeta $_ } ( "filename" , "file.text" );` [download]	[reply] [d/l] [select]

Apologies all. I've re-read all posts here and List::Util first does the trick. Thanks to all who replied!	[reply]
