Either of the following shell commands should work with grep 2.25: LC_ALL=C grep 31325 test grep -a 31325 test In my grep 2.25 (compiled from original source), these two commands are not equivalent.
They are not equivalent in general, though they should have the same behavior with this bug report's original test case. Sorry, I should have been clearer about that.
The difference is that grep -a treats the NUL byte as text, whereas LC_ALL=C grep treats it as binary. The latter has been longstanding behavior for quite some time.
