where to learn regex

[hecato]

OK, people. Where to learn regex that I dont need to read another tutorial. From time to time, I find myself doing little things with regex (in one langauge or other like: grep, PHP (time ago) and so on).

One time I solve my problem searching mainly for similar things or asking what I do wrong, I forget again of regex until I find me again solving something related.

Thus the question is, which one place you recommend for me don't go back and fort, and learn the "dam thing" now?.

Lang of your choice (I'm not restricted to one or other language), tips, hints, tricks, suguestions? welcome.

No tutorial? That makes a recommendation tough.

I would browse:

http://www.regular-expressions.info/

My number 1 reference is the "perlre" man page.

For education rather than reference purposes, the book "Mastering Regular Expressions" is a classic. IIRC the camel book ("Programming Perl") has a good introduction to regular expressions as well.

There are good books on this topic. I'd recommend to buy one of them from this list here: http://www.amazon.com/s/ref=nb_ss_gw/103-5157234-8269430?initialSearch=1&url=search-alias%3Daps&field-keywords=regular+expression&Go.x=0&Go.y=0&Go=Go

I personally have the "Mastering Regular Expressions" and I find it's quite useful. Details e.g. here:
http://www.amazon.com/Mastering-Regular-Expressions-Jeffrey-Friedl/dp/0596528124/ref=pd_bbs_sr_1/105-7086686-9287608?ie=UTF8&s=books&qid=1193351718&sr=8-1

I mean with "I dont need to read another tutorial" that after reading the material (tut, man page, reference, book, ...) I have learned enough for not read another material.

Ah, I see. You are looking for a more complete reference. That site might be useful, as will the book "Mastering Regular Expression", but as a single reference the site might be more useful.

As others have already mentioned: "Mastering Regular Expressions" by Jeffrey Friedl. An excellent book, so comprehensive, it'll make your head spin ;)

I read "o'reilly learning perl", and thought it was a good introduction to perl. The book also recommends "Mastering Regular Expressions". Read something about perl regex then that will help a lot for grep, sed, etc.

Hi people, I have also installed kiki and kudos (from the Ubuntu repos), they have helped me also, which other you recommend?

Also a python oriented: http://www.amk.ca/python/howto/regex/
