in reply to Regex: Searching for a string with special characters

I assume by 'brackets' you mean parentheses? That is, '(' and ')'?

Try using \Q ... \E in your regular expression if you want to 'escape' the string being searched against:

if ( ! /\Q$search\E/ ) { print "No Match found\n"; next; }

You can find more by reading perlre.

And another option is to use the qr/\Q$search\E/ syntax, which you can find in perlop.

Update:  Fixed wording (thanks for pointing that out, Hofmator++.)

Good luck!


s''(q.S:$/9=(T1';s;(..)(..);$..=substr+crypt($1,$2),2,3;eg;print$..$/

    Just a small annotation. This is only correct if it is supposed to be a general comment. The qr/$string/ construct has no influence on the escape issue whatsoever.

    For the escaping see also quotemeta.

      Thanks a lot.

      As mentioned by you, 'qr' didn't work for me but I was able to get the desired results using 'quotemeta'.
