53 utility modifies the file flags of the listed files
58 The options are as follows:
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.
74 Change the file flags for the file hierarchies rooted
83 or a file encountered during directory traversal is a symbolic link,
84 the file flags of the link itself is changed.
87 Flags are a comma separated list of keywords.
88 The following keywords are currently defined:
89 .Bd -literal -offset indent -compact
90 arch set the archived flag (super-user only)
91 opaque set the opaque flag (owner or super-user only)
92 nodump set the nodump flag (owner or super-user only)
93 sappnd set the system append-only flag (super-user only)
94 schg set the system immutable flag (super-user only)
95 uappnd set the user append-only flag (owner or super-user only)
96 uchg set the user immutable flag (owner or super-user only)
101 before an option causes the flag to be turned off.
103 .Bd -literal -offset indent -compact
104 nouchg the immutable bit should be cleared
112 options are ignored unless the
115 In addition, these options override each other and the
116 command's actions are determined by the last one specified.
123 is used to display the flags.
127 utility exits 0 on success, and \*[Gt]0 if an error occurs.
129 The kernel does not allow the flags on block and character
130 devices to be changed except by the super-user.
