Grep doesn't interpret \t as a valid escape sequence. This works: $ printf 'a a\nb\tb\nc c\n' | grep -v $'\t' a a c c if your shell is new enough to have $'' support; otherwise, type a literal tab in your shell window (often by 'ctrl-v tab' or 'ctrl-v ctrl-i'), and be sure you properly quote it. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
