Version 3.1.0 of rsync introduced the
--groupmap mentioned by Thomas, but also the convenience option
--chown, which works well for your scenario.
This option forces all files to be owned by USER with group GROUP.
This is a simpler interface than using --usermap and --groupmap directly,
but it is implemented using those options internally, so you cannot mix them.
If either the USER or GROUP is empty, no mapping for the omitted user/group will
occur. If GROUP is empty, the trailing colon may be omitted, but if USER is
empty, a leading colon must be supplied.
If you specify "--chown=foo:bar, this is exactly the same as specifying
"--usermap=*:foo --groupmap=*:bar", only easier.
-g options are required. Excluding them will fail to update their respective attribute, but produce no error.
rsync -og --chown=cmsseren:cmsseren [src] [dest]
This is mentioned indirectly in the manpage, which
states that the
--chown option "is implemented using
--groupmap internally", and:
--usermap option to have any effect, the
--owner) option must be used (or implied),
and the receiver will need to be running as a super-user (see also the
--groupmap option to have any effect, the
--groups) option must be used (or implied),
and the receiver will need to have permissions to set that group.
