chown

CHOWN(1)                                                           User Commands                                                          CHOWN(1)

NAME

       chown - change file owner and group

SYNOPSIS

       chown [OPTION]... [OWNER][:[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.  If only an owner
       (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
       owner  is  followed  by  a  colon  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 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 and group are given, but the owner is omitted, only the group of the files is changed;
       in this case, chown performs the same function as chgrp.  If only a colon is given, or if the entire operand is empty,  neither  the  owner
       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 is the 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 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  omit-
              ted, 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 '/'

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

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

       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 ':' following a  symbolic  OWNER.
       OWNER and GROUP may be numeric as well as symbolic.

EXAMPLES

       chown root /u
              Change the owner of /u to "root".

       chown root:staff /u
              Likewise, but also change its group to "staff".

       chown -hR root /u
              Change the owner of /u and subfiles to "root".
