So for example I'm trying to not match 'test'. I've tried [^t][^e][^s][^t]. It won't match it, but it also won't match if at least one of the characters match the notes in the same position.
Any idea how to get around this?
Just a note, this is POSIX version of regex, there are no look-aheads or look-behinds.
Also, to clarify, the word I want is between certain characters, i.e. for the string "sdkfjdlskj <dsfdjslj@example.com>" I am looking for everything between '<>'. The email part is easy, but not matching a certain word is quite boggling.
