57 utility sets the group ID of the file named by each
61 ID specified by the group operand.
63 The following options are available:
64 .Bl -tag -width indent
68 option is specified, symbolic links on the command line are followed.
69 (Symbolic links encountered in the tree traversal are not followed).
73 option is specified, all symbolic links are followed.
77 option is specified, no symbolic links are followed.
80 Recursively change file group IDs.
83 operand that names a directory,
85 shall change the group of the directory
86 and all files in the file hierarchy below it.
88 The force option ignores errors, except for usage errors and doesn't

91 If the file is a symbolic link, the group ID of the link itself is changed
