You are mixing Perl and a utility program in an odd way. Your example looks like it's trying to feed grep a slurp, and you want the file name, not the file contents. Either try: 

  my $output = `/usr/bin/grep "$prop" /path/to/file`;

Or try applying a regular expression to the contents of the file using only Perl.
