52 utility sets the group ID of the file named by each
56 ID specified by the group operand.
58 The following options are available:
59 .Bl -tag -width indent
63 option is specified, symbolic links on the command line are followed.
64 (Symbolic links encountered in the tree traversal are not followed.)
68 option is specified, all symbolic links are followed.
72 option is specified, no symbolic links are followed.
75 Change the group ID for the file hierarchies rooted
76 in the files instead of just the files themselves.
78 The force option ignores errors, except for usage errors and does not
79 query about strange modes (unless the user does not have proper permissions).
81 If the file is a symbolic link, the group ID of the link itself is changed
82 rather than the file that is pointed to.
86 to be verbose, showing files as the group is modified.
89 flag is specified more than once,
91 will print the filename, followed by the old and new numeric group ID.
93 File system mount points are not traversed.
101 options are ignored unless the
104 In addition, these options override each other and the
105 command's actions are determined by the last one specified.
109 operand can be either a group name from the group database,
110 or a numeric group ID.
111 If a group name is also a numeric group ID, the operand is used as a
116 must belong to the specified group and be the owner of the file,
117 or be the super-user.
119 .Bl -tag -width /etc/group -compact
126 In previous versions of this system, symbolic links did not have groups.
132 options are non-standard and their use in scripts is not recommended.
