SYNOPSIS
chown [OPTION]... OWNER[:[GROUP]] FILE...
chown [OPTION]... :GROUP FILE...
chown [OPTION]... --reference=RFILE FILE...
DESCRIPTION
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 interpreted 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.
OPTIONS
Change the owner and/or group of each FILE to OWNER and/or
GROUP.
-c, --changes
like verbose but report only when a change is made
--dereference
affect the referent of each symbolic link, rather
than the symbolic link itself
-h, --no-dereference
affect symbolic links instead of any referenced
file (available only on systems that can change the
ownership of a symlink)
--from=CURRENT_OWNER:CURRENT_GROUP
change the owner and/or group of each file only if
its current owner and/or group match those speci
fied here. Either may be omitted, in which case a
match is not required for the omitted attribute.
-f, --silent, --quiet
suppress most error messages
--reference=RFILE
use RFILE's owner and group rather than the speci
fied OWNER:GROUP values
-R, --recursive
