Not the problem he's trying to solve - he doesn't want line numbers.
By default, binary files won't print out the line (since it's not human
readable), but text files will. If you want to force line output, Bryan was
still on the right path, RTFM:
-a, --text
Process a binary file as if it were text; this
is equivalent to the
--binary-files=text option.
--binary-files=TYPE
If the first few bytes of a file indicate that the file
contains binary data, assume
that the file is of type TYPE. By default, TYPE is binary,
and grep normally outputs
either a one-line message saying that a binary file matches,
or no message if there is
no match. If TYPE is without-match, grep assumes that a
binary file does not match;
this is equivalent to the -I option. If TYPE is text, grep
processes a binary file as
if it were text; this is equivalent to the -a
option. Warning: grep
--binary-files=text might output binary garbage, which can
have nasty side effects if
the output is a terminal and if the terminal driver interprets
some of it as commands.
