Help with AWK

Hi, I need urgent help with trying to recover some data....basically I have a log file containing data such as EMAIL_ADDRESS = [test@test.com],NAME = [test], etc. This line of data can be anywhere in the file and in a thousand lines of data may only occur a hanful of times.
Now I need to be able to read through this file and extract all the email addresses. I want to extract the string EMAIL_ADDRESS = [test@test.com]. I have tried using awk to do this but I am not doing something quite right.
BEGIN { }
match($0, pattern) {

print substr($0, RSTART, RLENGTH);
}
pattern=/EMAIL_ADDRESS.*=.*\[.*\]/

END { }
Can anyone help please ?

phew, Friend, you've bit off a huge chunk. Have you ever looked at the email address specification (RFC-822 ftp://ftp.rfc-editor.org/in-notes/rfc822.txt)? The specification is extremely complicated, and writing a regex for it is nearly impossible for us mere mortals. As an example, the perl regex for e-mail addresses is over 60 lines long. To give you an idea, here is a perfectly legal email address:

Jeffy <"That Tall Guy"@ora.com (this address no longer active)>

imagine the fun of parsing that!! And this example hasn't taken advantage of but just a tiny portion of the freedoms in the specification.

I would seriously recommend using existing libraries if at all possible. I mentioned Perl, but there are implementations in nearly every language.

Good luck.
