  52 .Sh DESCRIPTION
  53 The
  54 .Nm
  55 utility modifies the file flags of the listed files
  56 as specified by the
  57 .Ar flags
  58 operand.
  59 .Pp
  60 The options are as follows:
  61 .Bl -tag -width indent
  62 .It Fl H
  63 If the
  64 .Fl R
  65 option is specified, symbolic links on the command line are followed.
  66 (Symbolic links encountered in the tree traversal are not followed.)
  67 .It Fl L
  68 If the
  69 .Fl R
  70 option is specified, all symbolic links are followed.
  71 .It Fl P
  72 If the
  73 .Fl R
  74 option is specified, no symbolic links are followed.
  75 This is the default.
  76 .It Fl R
  77 Change the file flags for the file hierarchies rooted
  78 in the files instead of just the files themselves.
  79 .El
  80 .Pp
  81 The flags are specified as an octal number or a comma separated list
  82 of keywords.
  83 The following keywords are currently defined:
  84 .Pp
  85 .Bl -tag -offset indent -width "opaque" -compact
  86 .It Ar arch
  87 set the archived flag (super-user only)
  88 .It Ar opaque
  89 set the opaque flag (owner or super-user only)
  90 .It Ar nodump
  91 set the nodump flag (owner or super-user only)
  92 .It Ar sappnd
  93 set the system append-only flag (super-user only)
  94 .It Ar schg
  95 set the system immutable flag (super-user only)
  96 .It Ar sunlnk
  97 set the system undeletable flag (super-user only)
  98 .It Ar uappnd
  99 set the user append-only flag (owner or super-user only)
 100 .It Ar uchg
 101 set the user immutable flag (owner or super-user only)
 102 .It Ar uunlnk
 103 set the user undeletable flag (owner or super-user only)
 104 .It Ar archived , sappend , schange , Xo
 105 .Ar simmutable , uappend , uchange , uimmutable ,
 106 .Ar sunlink , uunlink
 107 .Xc
 108 aliases for the above
 109 .El
 110 .Pp
 111 Putting the letters
 112 .Dq Ar no
 113 before an option causes the flag to be turned off.
 114 For example:
 115 .Bl -tag -offset indent -width "nouchg"
 116 .It Ar nouchg
 117 the immutable bit should be cleared
 118 .El
 119 .Pp
 120 Symbolic links do not have flags, so unless the
 121 .Fl H
 122 or
 123 .Fl L
 124 option is set,
 125 .Nm
 126 on a symbolic link always succeeds and has no effect.
 127 The
 128 .Fl H ,
 129 .Fl L
 130 and
 131 .Fl P
 132 options are ignored unless the
 133 .Fl R
 134 option is specified.
 135 In addition, these options override each other and the
 136 command's actions are determined by the last one specified.
 137 .Pp
 138 You can use "ls -lo" to see the flags of existing files.
