Actually Regex is taking more time instead of agrep. That's why the idea of using either agrep or find. This is small input.txt which I am using it as a input file. If there is any other way of increasing the speed of same Perl script, it is really required.

Are two system calls to agrep really faster than a single, well-crafted regex? This would be the first thing I'd look at to speed performance. _______________________________________________ Perl-Win32-Users mailing list Perl-Win32-Users@listserv.ActiveState.com To unsubscribe: http://listserv.ActiveState.com/mailman/mysubs -------------------------------------------------------- If you are not an intended recipient of this e-mail, please notify the sender, delete it and do not read, act upon, print, disclose, copy, retain or redistribute it.
