This is with SUSE's samba-3.0.21c-9.
Currently, smbclient offers the option
I would like to see the option to support
ls [options] [--] [pattern]
with options to sort the output as the normal "ls" does in the shell.
If one copies those options, one has:
-r reverse order while sorting
-S sort by file size
-t sort by modification time [The one I really miss!]
-X sort alphabetically by extension
