chown - change file owner and group
SYNOPSIS
chown[
,OPTION/]... [
,OWNER/][
,:/[
,GROUP/]]
,FILE/...
chown[
,OPTION/]...
,--reference=RFILE FILE/...
DESCRIPTION
This manual pagedocuments the GNU version of
chown.
chownchanges the user and/or group ownership of each given file. Ifonly an owner (a user name or numeric user ID) is given, that user is made theowner of each given file, and the files' group is not changed. If theowner is followed by a colon and a group name (or numeric group ID),with no spaces between them, the group ownership of the files ischanged as well. If a colon but no group name follows the user name,that user is made the owner of the files and the group of the files ischanged to that user's login group. If the colon and group are given,but the owner is omitted, only the group of the files is changed;in this case,
chownperforms the same function as
chgrp.If only a colon is given, or if the entire operand is empty, neither theowner nor the group is changed.
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
- -f, --silent, --quiet
- suppress most error messages
- -v, --verbose
- output a diagnostic for every file processed
- --dereference
- affect the referent of each symbolic link (this isthe default), rather than the symbolic link itself
- -h, --no-dereference
- affect symbolic links instead of any referenced file(useful only on systems that can change theownership of a symlink)
- --from=,CURRENT_OWNER/:CURRENT_GROUP
- change the owner and/or group of each file only ifits current owner and/or group match those specifiedhere. Either may be omitted, in which case a matchis not required for the omitted attribute
- --no-preserve-root

- --preserve-root
- fail to operate recursively on '/'
- --reference=,RFILE/
- use RFILE's owner and group rather thanspecifying OWNER:GROUP values

The following options modify how a hierarchy is traversed when the -Roption is also specified. If more than one is specified, only the finalone takes effect.
- -H
- if a command line argument is a symbolic linkto a directory, traverse it
- -L
- traverse every symbolic link to a directoryencountered
- -P
- do not traverse any symbolic links (default)
