57 utility changes the user ID and/or the group ID of the specified files.
58 Symbolic links named by arguments are silently left unchanged unless
62 The options are as follows:
67 option is specified, symbolic links on the command line are followed
68 and hence unaffected by the command.
69 (Symbolic links encountered during traversal are not followed.)
73 option is specified, all symbolic links are followed.
77 option is specified, no symbolic links are followed.
80 Change the user ID and/or the group ID of the file hierarchies rooted
81 in the files, instead of just the files themselves.
82 Beware of unintentionally matching the
84 hard link to the parent directory when using wildcards like
87 Do not report any failure to change file owner or group, nor modify
88 the exit status to reflect such failures.
90 If the file is a symbolic link, change the user ID and/or the
91 group ID of the link itself.
95 to be verbose, showing files as the owner is modified.
98 flag is specified more than once,
100 will print the filename, followed by the old and new numeric user/group ID.
102 File system mount points are not traversed.
110 options are ignored unless the
113 In addition, these options override each other and the
114 command's actions are determined by the last one specified.
120 operands are both optional, however, one must be specified.
123 operand is specified, it must be preceded by a colon (``:'') character.
127 may be either a numeric user ID or a user name.
128 If a user name is also a numeric user ID, the operand is used as a
132 may be either a numeric group ID or a group name.
133 If a group name is also a numeric group ID, the operand is used as a
136 The ownership of a file may only be altered by a super-user for
137 obvious security reasons.
141 Previous versions of the
143 utility used the dot (``.'') character to distinguish the group name.
144 This has been changed to be a colon (``:'') character so that user and
145 group names may contain the dot character.
147 On previous versions of this system, symbolic links did not have
154 options are non-standard and their use in scripts is not recommended.
