Use Perl like grep

prep () { perl -nle 'print if '"$1"';' $2 }
If you've ever tried "grep -P" you know how terrible it is. Even the man page describes it as "highly experimental". This function will let you 'grep' pipes and files using Perl syntax for regular expressions. The first argument is the pattern, e.g. '/foo/'. The second argument is a filename (optional).
Sample Output
% printf "some\nfake\ntext\n" | prep '/^\s?[Ff]ake\s?$/'
% printf "some\nfake\ntext\n" > file.txt

% prep '/^\s?[Ff]ake\s?$/' file.txt
