Behold, the power of Perl!
This one-liner should do it for you. You can either cat the file and pipe
it into this, or you can tack the filename on at the end.
perl -ne '/\000\000/ and print;'
In this form it won't print the filename before each line if you specify
more than one file, the way grep will. That takes a slightly longer
one-liner:
perl -ne '/\000\000/ and print "$ARGV:$_";'
Or, if you want the exact behavior of grep, only printing if more than one
file is specified:
perl -e '[EMAIL PROTECTED]; while(<>){ /\000\000/ and print
$f>1?"$ARGV:$_":$_ }'
