Mastering Regular Expressions by Jeff Friedl and published by O'Reilly will teach you everything you could possibly want to know about regex's and probably more. I found it most helpful because it taught me how to think about regular expressions in order to construct them. It eventually gets pretty advanced but the foundation that it lays is what I found most helpful. It's an outstanding book and I highly recommend it.

There is a real good chapter on pattern matching in the "Camel book" Programming Perl by O'Reilly press. The book should be available at any good library, poor web jockey, or old Linux hand. Ask around for it.

Good Luck,

Hi, I'm a Linux newbie and I am having a real hard time understanding regular expressions. Can anyone recommend a "ground-up" source for information on RE's?

I have two identical machines running SuSE8.0 with a vanilla kernel patched with freeswan ipsec. I just loaded both with 2.4.20 machine A boots flawless all services and scripts load no problem. However when I try to reboot machine B with 2.4.20 my firewall scipt fails because it's unable to load the ip_tables.o module. I logged in locally and tried loading the module manually and I get the error cannot locate module. The module is in the /lib/modules/2.4.20/kernel/net/ipv4/netfilter ... Could someone explain why this may be happening or how modules are loaded ie conf files or debug routines ..
