22 The chgrp utility will set the group ID of the file named by each file
23 operand to the group ID specified by the group operand.
24 For each file operand, it will perform actions equivalent to the
27 chown(2) function, called with the following arguments:
28 o The file operand will be used as the path argument.
30 o The user ID of the file will be used as the owner argument.
32 o The specified group ID will be used as the group argument.
34 Unless chgrp is invoked by a process with appropriate privileges, the
37 set-user-ID and set-group-ID bits of a regular file will be cleared
38 upon successful completion; the set-user-ID and set-group-ID bits of
39 other file types may be cleared.
40 The operating system has a configuration option
43 _POSIX_CHOWN_RESTRICTED, to restrict ownership changes. When this
44 option is in effect, the owner of the file may change the group of the
45 file only to a group to which the owner belongs. Only the super-user
46 can arbitrarily change owner IDs, whether or not this option is in
47 effect. To set this configuration option, include the following line in
48 /etc/system:
49 set rstchown = 1
51 To disable this option, include the following line in /etc/system:
55 set rstchown = 0
57 _POSIX_CHOWN_RESTRICTED is enabled by default. See system(4) and fpath‐
61 conf(2).

64 The following options are supported.
65 /usr/bin/chgrp and /usr/xpg4/bin/chgrp
67 -f Force. Does not report errors.
68 -h If the file is a symbolic link, this option changes the group of
71 the symbolic link. Without this option, the group of the file
72 referenced by the symbolic link is changed.
73 -H If the file specified on the command line is a symbolic link ref‐
76 erencing a file of type directory, this option changes the group
77 of the directory referenced by the symbolic link and all the
78 files in the file hierarchy below it. If a symbolic link is
79 encountered when traversing a file hierarchy, the group of the
80 target file is changed, but no recursion takes place.
81 -L If the file is a symbolic link, this option changes the group of
84 the file referenced by the symbolic link. If the file specified
85 on the command line, or encountered during the traversal of the
86 file hierarchy, is a symbolic link referencing a file of type
87 directory, then this option changes the group of the directory
88 referenced by the symbolic link and all files in the file hierar‐
89 chy below it.
90 -P If the file specified on the command line or encountered during
93 the traversal of a file hierarchy is a symbolic link, this option
94 changes the group of the symbolic link. This option does not fol‐
95 low the symbolic link to any other part of the file hierarchy.
96 -s The specified group is Windows SID. This option requires a file
99 system that supports storing SIDs, such as ZFS.
100 Specifying more than one of the mutually-exclusive options -H, -L, or
104 -P is not considered an error. The last option specified determines the
105 behavior of chgrp.
106 /usr/bin/chgrp
108 -R Recursive. chgrp descends through the directory, and any subdi‐
109 rectories, setting the specified group ID as it proceeds. When a
110 symbolic link is encountered, the group of the target file is
111 changed, unless the -h or -P option is specified. However, no
112 recursion takes place, unless the -H or -L option is specified.
113 /usr/xpg4/bin/chgrp
116 -R Recursive. chgrp descends through the directory, and any subdi‐
117 rectories, setting the specified group ID as it proceeds. When a
118 symbolic link is encountered, the group of the target file is
119 changed, unless the -h or -P option is specified. Unless the -H,
120 -L, or -P option is specified, the -L option is used as the
121 default mode.
122
125 The following operands are supported:
126 group A group name from the group database or a numeric group ID.
128 Either specifies a group ID to be given to each file named by
129 one of the file operands. If a numeric group operand exists in
130 the group database as a group name, the group ID number asso‐
131 ciated with that group name is used as the group ID.
132 file A path name of a file whose group ID is to be modified.
135
138 See largefile(5) for the description of the behavior of chgrp when
139 encountering files greater than or equal to 2 Gbyte (2^31 bytes).
140
142 See environ(5) for descriptions of the following environment variables
143 that affect the execution of chgrp: LANG, LC_ALL, LC_CTYPE, LC_MES‐
144 SAGES, and NLSPATH.
145
147 The following exit values are returned:
148 0 The utility executed successfully and all requested changes were
150 made.
151 >0 An error occurred.
