51 utility modifies the file flags of the listed files
56 The options are as follows:
57 .Bl -tag -width indent
61 option is specified, symbolic links on the command line are followed.
62 (Symbolic links encountered in the tree traversal are not followed.)
66 option is specified, all symbolic links are followed.
70 option is specified, no symbolic links are followed.
73 Change the file flags for the file hierarchies rooted
74 in the files instead of just the files themselves.
77 The flags are specified as an octal number or a comma separated list
79 The following keywords are currently defined:
81 .Bl -tag -offset indent -width ".Ar opaque"
82 .It Ar arch , archived
83 set the archived flag (super-user only)
85 set the opaque flag (owner or super-user only)
87 set the nodump flag (owner or super-user only)
88 .It Ar sappnd , sappend
89 set the system append-only flag (super-user only)
90 .It Ar schg , schange , simmutable
91 set the system immutable flag (super-user only)
92 .It Ar sunlnk , sunlink
93 set the system undeletable 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)
98 .It Ar uunlnk , uunlink
99 set the user undeletable flag (owner or super-user only)
104 before or removing the letters
106 from a keyword causes the flag to be cleared.
109 .Bl -tag -offset indent -width "nouchg" -compact
111 clear the user immutable flag (owner or super-user only)
113 clear the nodump flag (owner or super-user only)
116 Symbolic links do not have flags, so unless the
122 on a symbolic link always succeeds and has no effect.
128 options are ignored unless the
131 In addition, these options override each other and the
132 command's actions are determined by the last one specified.
134 You can use "ls -lo" to see the flags of existing files.
