  50 .Sh DESCRIPTION
  51 The
  52 .Nm
  53 utility modifies the file flags of the listed files
  54 as specified by the
  55 .Ar flags
  56 operand.
  57 .Pp
  58 The options are as follows:
  59 .Bl -tag -width indent
  60 .It Fl f
  61 Do not display a diagnostic message if
  62 .Nm
  63 could not modify the flags for
  64 .Va file ,
  65 nor modify the exit status to reflect such failures.
  66 .It Fl H
  67 If the
  68 .Fl R
  69 option is specified, symbolic links on the command line are followed.
  70 (Symbolic links encountered in the tree traversal are not followed.)
  71 .It Fl h
  72 If the
  73 .Ar file
  74 is a symbolic link,
  75 change the file flags of the link itself rather than the file to which it points.
  76 .It Fl L
  77 If the
  78 .Fl R
  79 option is specified, all symbolic links are followed.
  80 .It Fl P
  81 If the
  82 .Fl R
  83 option is specified, no symbolic links are followed.
  84 This is the default.
  85 .It Fl R
  86 Change the file flags for the file hierarchies rooted
  87 in the files instead of just the files themselves.
  88 .It Fl v
  89 Cause
  90 .Nm
  91 to be verbose, showing filenames as the flags are modified.
  92 If the
  93 .Fl v
  94 option is specified more than once, the old and new flags of the file
  95 will also be printed, in octal notation.
  96 .El
  97 .Pp
  98 The flags are specified as an octal number or a comma separated list
  99 of keywords.
 100 The following keywords are currently defined:
 101 .Pp
 102 .Bl -tag -offset indent -width ".Cm opaque"
 103 .It Cm arch , archived
 104 set the archived flag (super-user only)
 105 .It Cm opaque
 106 set the opaque flag (owner or super-user only).
 107 [Directory is opaque when viewed through a union mount]
 108 .It Cm nodump
 109 set the nodump flag (owner or super-user only)
 110 .It Cm sappnd , sappend
 111 set the system append-only flag (super-user only)
 112 .It Cm schg , schange , simmutable
 113 set the system immutable flag (super-user only)
 114 .It Cm uappnd , uappend
 115 set the user append-only flag (owner or super-user only)
 116 .It Cm uchg , uchange , uimmutable
 117 set the user immutable flag (owner or super-user only)
 118 .It Cm hidden
 119 set the hidden flag
 120 [Hide item from GUI]
 121 .El
 122 .Pp
 123 Putting the letters
 124 .Dq Ar no
 125 before or removing the letters
 126 .Dq Ar no
 127 from a keyword causes the flag to be cleared.
 128 For example:
 129 .Pp
 130 .Bl -tag -offset indent -width "nouchg" -compact
 131 .It Ar nouchg
 132 clear the user immutable flag (owner or super-user only)
 133 .It Ar dump
 134 clear the nodump flag (owner or super-user only)
 135 .El
 136 .Pp
 137 Unless the
 138 .Fl H
 139 or
 140 .Fl L
 141 options are given,
 142 .Nm
 143 on a symbolic link always succeeds and has no effect.
 144 The
 145 .Fl H ,
 146 .Fl L
 147 and
 148 .Fl P
 149 options are ignored unless the
 150 .Fl R
 151 option is specified.
 152 In addition, these options override each other and the
 153 command's actions are determined by the last one specified.
 154 .Pp
 155 You can use "ls -lO" to see the flags of existing files.

 164 .Sh HISTORY
 165 The
 166 .Nm
 167 command first appeared in
 168 .Bx 4.4 .
 169 .Sh BUGS
 170 Only a limited number of utilities are
 171 .Nm
 172 aware.
 173 Some of these tools include
 174 .Xr ls 1 ,
 175 .Xr cp 1 ,
 176 .Xr find 1 ,
 177 .Xr install 1 ,
 178 .Xr dump 8 ,
 179 and
 180 .Xr restore 8 .
 181 In particular a tool which is not currently
 182 .Nm
 183 aware is the
 184 .Xr pax 1
 185 utility.
