Re: say if grep can find non-ascii

[Dan Jacobson]

There should be some mention of how one is to give control characters
as arguments to grep. If one must one do
$ grep $'\x00' file.txt, etc.
And if without bash handy, must one pass them raw right there as
arguments?  I.e., document if there is a way or no way to describe
arbitrary octets or must one pass them raw.
