56 utility modifies the file flags of the listed files
61 The options are as follows:
62 .Bl -tag -width indent
66 option is specified, symbolic links on the command line are followed.
67 (Symbolic links encountered in the tree traversal are not followed.)
71 option is specified, all symbolic links are followed.
75 option is specified, no symbolic links are followed.
78 Change the file flags for the file hierarchies rooted
79 in the files instead of just the files themselves.
82 The flags are specified as an octal number or a comma separated list
84 The following keywords are currently defined:
86 .Bl -tag -offset indent -width "opaque" -compact
88 set the archived flag (super-user only)
90 set the opaque flag (owner or super-user only)
92 set the nodump flag (owner or super-user only)
94 set the system append-only flag (super-user only)
96 set the system immutable flag (super-user only)
98 set the system undeletable flag (super-user only)
100 set the user append-only flag (owner or super-user only)
102 set the user immutable flag (owner or super-user only)
104 set the user undeletable flag (owner or super-user only)
105 .It Ar archived , sappend , schange , Xo
106 .Ar simmutable , uappend , uchange , uimmutable ,
107 .Ar sunlink , uunlink
109 aliases for the above
114 before or removing the letters
116 from a keyword causes the flag to be cleared.
119 .Bl -tag -offset indent -width "nouchg" -compact
121 clear the user immutable flag (owner or super-user only)
123 clear the nodump flag (owner or super-user only)
126 Symbolic links do not have flags, so unless the
132 on a symbolic link always succeeds and has no effect.
138 options are ignored unless the
141 In addition, these options override each other and the
142 command's actions are determined by the last one specified.
144 You can use "ls -lo" to see the flags of existing files.
