Regex match everything after parenthesis

Question

I am trying to bulk rename around 10,000 files. I have a tool which can use Regex to do this.

I simply need a regex matching " (" and everything after that (space, parenthesis, everything).

Anyone able to help with this really simple problem real fast?

Answer 1

If you want the open parantheses included in the match:

/ \(.*/

If not, use a positive lookbehind:

/(?<= \().*/

Answer 2

You should really check out a tutorial , since this is probably the easiest thing you can do with regex. This should do:

[ ]\(.*

The square brackets are just to visualize the space. They can (but don't have to) be omitted.

Answer 3

Parentheses are meta-characters in regex, ie they mean something special. If you want to signify a literal character that happens to be a meta-character, you need to escape it using a backslash ( \\ ). For example, consider the caret ( ^ ), which is a meta-character that matches the beginning of a string.

^abcd
matches strings beginning with the sequence of characters "abcd"

\^abcd
matches the sequence of characters "^abcd"
