ok, I'm seeing it, now just have to learn the syntax :P

Code:

sed 's/old/new/g' input.txt > output.txt

interesting, I need it to do some regexp matching though, the old url's are all different, and I want to match them all with one command

wildcard to match any type of link? Sure!

Code:

/a[\s]+[^>]*?href[\s]?=[\s\"\']+(.*?)[\"\']+.*?>([^<]+|.*?)?<\/a>/i

Enjoy.

edit: not working for some reason, is the code right and I am doing something wrong? using regexp search but not matching

download textpad, it works great.

press F8, then use .*. as the wild card.

The above is Perl Regex, not "universal" regex.

I just use TextPad for that kind of shit when on Windows It usually takes normal, or semi-perl regex just fine. Sorry, never used NP++.

found the answer:

Code:

<a href="[^"]+">[^<]+</a>

thanks for the help, it was interesting, maybe this thread will help someone else too
