POSIX can only mandate what portable uses are limited to. You are correct that there is no portable way, via POSIX options alone, to make ls change what units it displays in, other than what POSIX requires of '-k' (which affects only the -s column and the per-directory summary). But POSIX does not (and cannot) mandate against extensions, and we have not removed any of coreutils' extensions - we merely removed -k as a synonym of the extension --block-size=..., because the POSIX specification of -k is incompatible with the --block-size= extension semantics that we did not change. If you think there is an extension missing in ls to display something that you need, feel free to write a patch to provide that extension - we have long desired to have a --format option that would let you choose which pieces of information to display and in what order. -- Eric Blake eblake redhat com +1-919-301-3266 Libvirt virtualization library http://libvirt.org
