regular expressions dilma

Hello all,

I just want to know that whether constructing regular expression are the same for any languages( uinx shell script, java script, java, etc), and if it varies are they significant, in the sense that do I have to learn them individually. What I am tring to say is that I would like to learn how to construct regular expression in general and then apply them when and where they needed regardless of the programming language being used. Also any recommendation for a good regular expression tutorial would be greatly appreciated.

Thanks in advance,

staph

When I first started using Unix a friend recommended This . It's pretty good, but I have a hard time using it as I'm not good at learning from books. I'm more the slowly stumble through things until they start to make sense type.

So far as whether they're all the same, each language is exactly that, a language. A lot may have things in common, like Spanish is to Italian, but there are differences.

I've been going through Friedl's Mastering Regular Expressions and it's quite good, though too slow/basic for my tastes. The good news is that even if you don't know regular expressions it's enough to take you to a fairly high level of mastery.
