'&> word' and '>& word' on non-integer word are bash-isms (actually, &> is preferred, because '>&$x' is ambiguous if you don't know if x expands to an integer or a file name), and bash treats both as shorthand for '> word 2>&1'. Therefore, the correct replacement for dash (or any other POSIX shell that doesn't understand bash's extension) would be: kill -0 $virsh_pid >/dev/null 2>&1 || break At any rate, ACK with that squashed in, so I pushed it. -- Eric Blake eblake(a)redhat.com +1-801-349-2682 Libvirt virtualization library http://libvirt.org
