(favor)im coming

(favour)sure

(favours)nothing but this

CodePudding user response：

The following regex will work as long as you don't have any nested parentheses:

(?<=^|\))[^(\r\n]

Test it here.

Explanation: Match the rest of the line after the closing parenthesis, or if the line doesn't contain any parentheses, just match the whole line.

PS: This is PCRE syntax. You'll need to use a PCRE compatible regex library. If you are using a shell script, grep -P works.
