70 utility changes the user ID and/or the group ID of the specified files.
71 Symbolic links named by arguments are silently left unchanged unless
75 The options are as follows:
80 option is specified, symbolic links on the command line are followed.
81 (Symbolic links encountered in the tree traversal are not followed.)
85 option is specified, all symbolic links are followed.
89 option is specified, no symbolic links are followed.
92 Change the user ID and/or the group ID of the specified directory trees
93 (recursively, including their contents) and files.
94 Beware of unintentionally matching the
96 hard link to the parent directory when using wildcards like
99 Don't report any failure to change file owner or group, nor modify
100 the exit status to reflect such failures.
102 If the file is a symbolic link, change the user ID and/or the
103 group ID of the link itself.

153 utility used the dot (``.'') character to distinguish the group name.
154 This has been changed to be a colon (``:'') character so that user and
