Can you elaborate on that difference in behavior? I mean the
difference between
echo foo | grep -f empty-directory/
This should be a hard failure. Asking grep to open a directory and
search for patterns in it is wrong.
and
echo foo | grep -f empty-file
This should search for "no pattern", and hence print nothing but still
consume the input.
So, these should print nothing:
echo foo | grep -f /dev/null
echo foo | (grep -f /dev/null; cat)
This should print an error message:
echo foo | grep -f /
This should print an error message followed by "foo":
echo foo | (grep -f /; cat)
If you get XPASSes from the last two on Windows, that's good. :) It's
working better than POSIX. :)
