We recommend that you NEVER parse ls output, as it is inherently ambiguous and difficult to parse. MUCH better is to use stat instead of ls, at which point you can get directly at the information you want without having to post-process potentially ambiguous output. If anything, added documents should point people to stat, not to bad ways of parsing ls. -- Eric Blake, Principal Software Engineer Red Hat, Inc. +1-919-301-3266 Virtualization: qemu.org | libvirt.org
