DESCRIPTION
/usr/bin/chown and /usr/xpg4/bin/chown
The chown utility sets the user ID of the file named by each file to
the user ID specified by owner, and, optionally, sets the group ID to
that specified by group.
If chown is invoked without the {PRIV_FILE_SETID} privilege, the set-
user-ID and set-group-ID bits are cleared.
Changing the owner of a file may require additional privilege. The
{PRIV_FILE_CHOWN} privilege allows changing the owner of files owned by
other users, but does not allow changing the owner to or from uid 0.
The {PRIV_FILE_CHOWN_SELF} privilege allows the file's current owner to
change the owner to another uid, except for uid 0. Changing a file's
owner to uid 0 requires all privileges.
The file system has a mountpoint option, rstchown, to restrict owner‐
ship changes. When this option is in effect the owner of the file is
prevented from changing the owner ID of the file, unless they use the
privileges listed above. When this option is not in effect, the owner
of the file does not need additional privilege to change the owner to
another non-zero uid. The _POSIX_CHOWN_RESTRICTED option will be
reported as true for paths on filesystems mounted with the rstchown
option, when checked with fpathconf(2) or getconf(1).
chown changes the ownership of each file to owner. owner can be speci‐
fied as either a user name or a numeric user id. The group ownership of
each file can also be changed to group by appending :group to the user
name.
OPTIONS
The following options are supported for /usr/bin/chown:
-c, --changes
Like verbose (-v | --verbose). Reports only when a change is made.
-f, --silent, --quiet
Force. Does not report errors.
--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
-h, --no-dereference
If the file is a symbolic link, this option changes the owner of
the symbolic link. Without this option, the owner of the file ref‐
erenced by the symbolic link is changed.
--help
Display usage message and exit.
-H
If the file specified on the command line is a symbolic link refer‐
encing a file of type directory, this option changes the owner of
the directory referenced by the symbolic link and all the files in
the file hierarchy below it. If a symbolic link is encountered when
traversing a file hierarchy, the owner of the target file is
changed, but no recursion takes place.
-L
If the file is a symbolic link, this option changes the owner of
the file referenced by the symbolic link. If the file specified on
the command line, or encountered during the traversal of the file
hierarchy, is a symbolic link referencing a file of type directory,
then this option changes the owner of the directory referenced by
the symbolic link and all files in the file hierarchy below it.
--no-preserve-root
Do not treat '/' specially. This is the default.
--preserve-root
Do not operate recursively on '/'.
-P
If the file specified on the command line or encountered during the
traversal of a file hierarchy is a symbolic link, this option
changes the owner of the symbolic link. This option does not follow
the symbolic link to any other part of the file hierarchy.
--reference=RFILE
Uses RFILE's owner and group. If RFILE is missing, then gives a
diagnostic error message and returns a non-zero exit code. This
option and -s option are mutually exclusive.
-R, --recursive
Recursive. chown descends through the directory, and any subdirec‐
tories, setting the specified group ID as it proceeds. When a sym‐
bolic link is encountered, the group of the target file is changed,
unless the -h or -P option is specified. However, no recursion
takes place, unless the -H or -L option is specified.
-s
The owner and/or group arguments are Windows SID strings. This
option requires a file system that supports storing SIDs, such as
ZFS. This option and --reference option are mutually exclusive.
-v, --verbose
Give a diagnostic for every file processed.
Specifying more than one of the mutually-exclusive options -H, -L, or
-P is not considered an error. The last option specified determines the
behavior of chown.
The following options are supported for /usr/xpg4/bin/chown:
-f Force. Does not report errors.
-h If the file is a symbolic link, this option changes the owner of
the symbolic link. Without this option, the owner of the file
referenced by the symbolic link is changed.
-H If the file specified on the command line is a symbolic link ref‐
erencing a file of type directory, this option changes the group
of the directory referenced by the symbolic link and all the
files in the file hierarchy below it. If a symbolic link is
encountered when traversing a file hierarchy, the group of the
target file is changed, but no recursion takes place.
-L If the file is a symbolic link, this option changes group of the
file referenced by the symbolic link. If the file specified on
the command line, or encountered during the traversal of the file
hierarchy, is a symbolic link referencing a file of type direc‐
tory, then this option changes the group of the directory refer‐
enced by the symbolic link and all files in the file hierarchy
below it.
-P If the file specified on the command line or encountered during
the traversal of a file hierarchy is a symbolic link, this option
changes the group of the symbolic link. This option does not fol‐
low the symbolic link to any other part of the file hierarchy.
-R Recursive. chown descends through the directory, and any subdi‐
rectories, setting the specified group ID as it proceeds. When a
symbolic link is encountered, the group of the target file is
changed, unless the -h or -P option is specified. Unless the -H,
-L, or -P option is specified, the -L option is used as the
default mode.
-s The specified group is Windows SID. This option requires a file
system that supports storing SIDs, such as ZFS.
Specifying more than one of the mutually-exclusive options -H, -L, or
-P is not considered an error. The last option specified determines the
behavior of chown.
OPERANDS
The following operands are supported:
owner[:group] A user ID and optional group ID to be assigned to
file. The owner portion of this operand must be a user
name from the user database or a numeric user ID.
Either specifies a user ID to be given to each file
named by file. If a numeric owner exists in the user
database as a user name, the user ID number associated
with that user name is used as the user ID. Similarly,
if the group portion of this operand is present, it
must be a group name from the group database or a
numeric group ID. Either specifies a group ID to be
given to each file. If a numeric group operand exists
in the group database as a group name, the group ID
number associated with that group name is used as the
group ID.
file A path name of a file whose user ID is to be modified.
EXAMPLES
Example 1 Changing Ownership of All Files in the Hierarchy
The following command changes ownership of all files in the hierarchy,
including symbolic links, but not the targets of the links:
example% chown −R −h owner[:group] file...
ENVIRONMENT VARIABLES

SAGES, and NLSPATH.
EXIT STATUS

made.
>0 An error occurred.

NOTES
chown is CSI-enabled except for the owner and group names.
In previous releases of Solaris, there was a /usr/ucb/chown command
which had different -R semantics with respect to how symbolic links
were handled. /usr/ucb/chown changed ownership of the symbolic link but
not the target file. To get this behavior with /usr/bin/chown, addi‐
tional flags need to be specified.
