How to list all files with white spaces the after php tag

Question

Is it possible with linux commands to List all files with white spaces the after php tag at the end of file?

Answer 1

Answer using pcregrep which will match even if your whitespace spans onto new lines:

pcregrep -rM '\?>[\s]+[^\S]*$' *.php

Untested though because I don't have pcregrep installed on this computer. Please correct me if you know it to be incorrect.

This should match all files that end with ?> followed by only whitespace. If it's followed by any other character, then it won't match (e.g. if it's not an all-PHP file and needs ?>)
