57 utility modifies the file flags of the listed files
62 The options are as follows:
63 .Bl -tag -width indent
67 option is specified, symbolic links on the command line are followed.
68 (Symbolic links encountered in the tree traversal are not followed.)
73 change the mode of the link itself rather than the file to which it points.
77 option is specified, all symbolic links are followed.
81 option is specified, no symbolic links are followed.
84 Change the file flags for the file hierarchies rooted
85 in the files instead of just the files themselves.
88 The flags are specified as an octal number or a comma separated list
90 The following keywords are currently defined:
92 .Bl -tag -offset indent -width "nouhistory" -compact
94 set the archived flag (super-user only)
96 set the opaque flag (owner or super-user only)
98 set the nodump flag (owner or super-user only)
100 set the system nohistory flag (super-user only)
102 set the user nohistory flag (owner or super-user only)
104 set the system append-only flag (super-user only)
106 set the system immutable flag (super-user only)
108 set the system undeletable flag (super-user only)
110 set the user append-only flag (owner or super-user only)
112 set the user immutable flag (owner or super-user only)
114 set the user undeletable flag (owner or super-user only)
115 .It Ar archived , sappend , schange , Xo
116 .Ar simmutable , uappend , uchange , uimmutable ,
117 .Ar sunlink , uunlink
119 aliases for the above
127 before or removing the letters
129 from a keyword causes the flag to be cleared.
132 .Bl -tag -offset indent -width "nouchg" -compact
134 clear the user immutable flag (owner or super-user only)
136 clear the nodump flag (owner or super-user only)
146 on a symbolic link always succeeds and has no effect.
152 options are ignored unless the
155 In addition, these options override each other and the
156 command's actions are determined by the last one specified.
158 You can use "ls -lo" to see the flags of existing files.
