Hi grep maintainers, This behaviour, with grep 3.3 built from source, is a bit surprising:
$ echo hello >thing $ grep -L goodbye thing && echo OK thing OK $ grep -L goodbye thing >/dev/null && echo OK $ That is, when using -L, redirecting stdout to /dev/null has the same effect on the exit code as specifying -q (the behaviour with -q is described in the "Exit Status" section of the manual). This is a bit awkward if you're using grep in a script, because you don't necessarily have any control over whether stdout is /dev/null or not.
