DESCRIPTION
The chgrp utility will set the group ID of the file named by each file
operand to the group ID specified by the group operand.
For each file operand, it will perform actions equivalent to the
chown(2) function, called with the following arguments:
o The file operand will be used as the path argument.
o The user ID of the file will be used as the owner argument.
o The specified group ID will be used as the group argument.
Unless chgrp is invoked with the {PRIV_FILE_SETID} privilege, the set-
user-ID and set-group-ID bits of a regular file will be cleared upon
successful completion; the set-user-ID and set-group-ID bits of other
file types may be cleared.
The file system has a mountpoint option, rstchown, to restrict owner‐
ship changes. When this option is in effect, the owner of the file may
change the group of the file only to a group to which the owner
belongs. 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).
The privilege {PRIV_FILE_CHOWN_SELF} allows a process to behave as if
rstchown is disabled, whether or not the mount option is in effect. The
privilege {PRIV_FILE_CHOWN} allows a process to change the group ID of
any file to any group, whether or not the file is owned by the effec‐
tive user id of the process, even if the effective user is not a member
of that group.
OPTIONS
The following options are supported for /usr/bin/chgrp:
-c, --changes Like verbose (-v | --verbose). Reports only
when a change is made.
-f, --silent, --quiet Force. Does not report errors.
-h, --no-dereference If the file is a symbolic link, this option
changes the group of the symbolic link. With‐
out this option, the group of the file refer‐
enced 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 referencing 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 the 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 directory,
then this option changes the group 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 group of the symbolic link. This
option does not follow the symbolic link to
any other part of the file hierarchy.
--reference=RFILE Use group name of RFILE. If RFILE is non-exis‐
tent, an error message is displayed and
returns a non-zero exit code. This option and
-s option are mutually exclusive.
-R, --recursive Recursive. chgrp descends through the direc‐
tory, and any subdirectories, 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 specified group is Windows SID. 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 chgrp.
The following options are supported for /usr/xpg4/bin/chgrp:
-f Force. Does not report errors.
-R Recursive. chgrp 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.
-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.
-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 chgrp.
OPERANDS
The following operands are supported:
group A group name from the group database or a numeric group ID.
Either specifies a group ID to be given to each file named by
one of the file operands. If a numeric group operand exists in
the group database as a group name, the group ID number asso‐
ciated with that group name is used as the group ID.
file A path name of a file whose group ID is to be modified.

SAGES, and NLSPATH.
EXIT STATUS
The following exit values are returned:

made.
>0 An error occurred.
