I'm asking something which is probably pretty easy, but I can't find a way with the string functions (probably because I didn't understand how the $str*** functions work).
I want to select just the string between two square parenthesis.
As example, in:
1983 - Kill 'Em All [25DP 5339]
I just want [25DP 5339] (possibly with the parenthesis, but everything will work.
How can I do that?
