52 utility modifies the file flags of the listed files
57 The options are as follows:
58 .Bl -tag -width indent
62 option is specified, symbolic links on the command line are followed.
63 (Symbolic links encountered in the tree traversal are not followed.)
67 option is specified, all symbolic links are followed.
71 option is specified, no symbolic links are followed.
74 Change the file flags for the file hierarchies rooted
75 in the files instead of just the files themselves.
78 The flags are specified as an octal number or a comma separated list
80 The following keywords are currently defined:
82 .Bl -tag -offset indent -width ".Ar opaque"
83 .It Ar arch , archived
84 set the archived flag (super-user only)
86 set the opaque flag (owner or super-user only).
87 [Directory is opaque when viewed through a union mount]
89 set the nodump flag (owner or super-user only)
90 .It Ar sappnd , sappend
91 set the system append-only flag (super-user only)
92 .It Ar schg , schange , simmutable
93 set the system immutable flag (super-user only)
94 .It Ar uappnd , uappend
95 set the user append-only flag (owner or super-user only)
96 .It Ar uchg , uchange , uimmutable
97 set the user immutable flag (owner or super-user only)
109 flags may only be unset when the system is in single-user mode.
113 before or removing the letters
115 from a keyword causes the flag to be cleared.
118 .Bl -tag -offset indent -width "nouchg" -compact
120 clear the user immutable flag (owner or super-user only)
122 clear the nodump flag (owner or super-user only)
131 on a symbolic link always succeeds and has no effect.
137 options are ignored unless the
140 In addition, these options override each other and the
141 command's actions are determined by the last one specified.
143 You can use "ls -lO" to see the flags of existing files.
