NAME

chown - 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. With
--reference, change the owner and group of each FILE to those of RFILE.


-c, --changes
like verbose but report only when a change is made


--dereference
affect the referent of each symbolic link, rather than the sym-
bolic link itself


-h, --no-dereference
affect each symbolic link instead of any referenced file (useful
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 specified here. Either may be
omitted, in which case a match is not required for the omitted
attribute.


--no-preserve-root do not treat "/" specially (the default)


--preserve-root
fail to operate recursively on "/"


-f, --silent, --quiet
suppress most error messages


--reference=RFILE
use RFILE"s owner and group rather than the specifying
OWNER:GROUP values


-R, --recursive
operate on files and directories recursively


-v, --verbose
output a diagnostic for every file processed


The following options modify how a hierarchy is traversed when the -R
option is also specified. If more than one is specified, only the
final one takes effect.


-H if a command line argument is a symbolic link to a directory,
traverse it


-L traverse every symbolic link to a directory encountered


-P do not traverse any symbolic links (default)


--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 ":". OWNER and GROUP may be
numeric as well as symbolic.
