Regex to remove the first 4 characters

nynaevelan · 07-19-2014, 01:52 PM

Hi:

I did a search but I couldn't find an answer which I understood that will help me to remove the first four characters from a title. Any regex gurus out there willing to help me figure this out?? Pretty please.

(\w){4} might do it
The {4} says exactly 4 of the preceeding

If you know absolutely that you want to remove the first 4 characters no matter what they are then:

Search: ^....(.*)
Replace: \1

Voila. The search regexp says "Anchored at the beginning, accept 4 of any character, then keep the rest in the first group". The replacement says "replace everything with the first group". The key to make this work is the "^", which says that the regexp *must* start at the beginning of the value.
