CHOWN (1)
change file owner and group
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)
-f, --silent, --quiet
suppress most error messages
--reference=RFILE
use RFILE's owner and group rather than
the specified OWNER.GROUP values
-R, --recursive
operate on files and directories recursively
-v, --verbose
output a diagnostic for every file processed
--help
display this help and exit
--version
output version information and exit
Owner is unchanged if missing. Group is unchanged if missing, but changed
to login group if implied by a period. A colon may replace the period.
