chown - change file owner and group
chown [OPTION]... OWNER[:[GROUP]] FILE...
chown [OPTION]... :GROUP FILE...
chown [OPTION]... --reference=RFILE FILE...
This manual page documents the GNU version of chown. chown
changes the user and/or group ownership of each given file,
according to its first non-option argument, which is inter-
preted as follows. If only a user name (or numeric user ID)
is given, that user is made the owner of each given file,
and the files' group is not changed. If the user name is
followed by a colon or dot and a group name (or numeric
group ID), with no spaces between them, the group ownership
of the files is changed as well. If a colon or dot but no
group name follows the user name, that user is made the
owner of the files and the group of the files is changed to
that user's login group. If the colon or dot and group are
given, but the user name is omitted, only the group of the
files is changed; in this case, chown performs the same
function as chgrp.
Change the owner and/or group of each FILE to OWNER and/or

the symbolic link itself

(available only on systems that can change the owner-
ship of a symlink)
change the owner and/or group of each file only if its
current owner and/or group match those specified here.
Either may be omitted, in which case a match is not
required for the omitted attribute.

Owner is unchanged if missing. Group is unchanged if miss-
ing, but changed to login group if implied by a `:'. OWNER
and GROUP may be numeric as well as symbolic.
