G'day praveensam, Welcome to the monastery. I'd recommend the following in the indicated order: perlrequick - Perl regular expressions quick start perlretut - Perl regular expressions tutorial perlre - Perl regular expressions (the rest of the story) Search the perl manual page (for '`regular expression`') to find links to other related pages. Be aware, some of these are fairly advanced. -- Ken	[reply] [d/l]

The other references given are all free, but if you've got some cash you're desperate to get rid of, you can't do better, IMHO, than Jeffrey Friedl's Mastering Regular Expressions (O'Reilly). (Friedl's website: regex.info)	[reply]

One other tangential source for learning regex's that has/does help me is an editor like sublime(non-free) that shows matches as you type in your regex. I have run into just a couple along the way over the years that behave like this. Unfortunately, I don't recall them all, only sublime. Very handy when learning to be able to have instant feedback when constructing an regex... :-) Just a thought... ...the majority is always wrong, and always the last to know about it... Insanity: Doing the same thing over and over again and expecting different results.	[reply]
