2 lines will do it:
use File::Slurp ;
unless( read_file( $file ) =~ /$whatever/ ) {
# do something
}
faster and cleaner than the line by line methods others have posted.
and if you want even more speed, and the file is long, then shell out to
the grep utility and it has an option to only show you if a line
is/isn't in file. i normally don't recommend shelling out but that would
likely be the fastest solution for a large file.
