You want 'grep -L "hi there" ./empty', which says to print the names of all files that did not contain any match (and not the names of all files that had lines that didn't match). That is, -v and -L are different types of negation. $ grep -L '' empty empty $ grep -Lv '' empty empty The empty file has no matches to any patterns (whether or not the pattern is negated with -v), so it shows up under -L. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
