+.Sh NAME
+.Nm chflags
+.Nd change file flags
+.Sh SYNOPSIS
+.Nm
+.Op Fl fhv
+.Oo
+.Fl R
+.Op Fl H | Fl L | Fl P
+.Oc
+.Ar flags
+.Ar
+.Sh DESCRIPTION
+The
+.Nm
+utility modifies the file flags of the listed files
+as specified by the
+.Ar flags
+operand.
+.Pp
+The options are as follows:
+.Bl -tag -width indent
+.It Fl f
+Do not display a diagnostic message if
+.Nm
+could not modify the flags for
+.Va file ,
+nor modify the exit status to reflect such failures.
+.It Fl H
+If the
+.Fl R
+option is specified, symbolic links on the command line are followed.
+(Symbolic links encountered in the tree traversal are not followed.)
+.It Fl h
+If the
+.Ar file
+is a symbolic link,
+change the file flags of the link itself rather than the file to which it points.
+.It Fl L
+If the
+.Fl R
+option is specified, all symbolic links are followed.
+.It Fl P
+If the
+.Fl R
+option is specified, no symbolic links are followed.
+This is the default.
+.It Fl R
+Change the file flags for the file hierarchies rooted
+in the files instead of just the files themselves.
+.It Fl v
+Cause
+.Nm
+to be verbose, showing filenames as the flags are modified.
+If the
+.Fl v
+option is specified more than once, the old and new flags of the file
+will also be printed, in octal notation.
+.El
+.Pp
+The flags are specified as an octal number or a comma separated list
+of keywords.
+The following keywords are currently defined:
+.Pp
+.Bl -tag -offset indent -width ".Cm opaque"
+.It Cm arch , archived
+set the archived flag (super-user only)
+.It Cm opaque
+set the opaque flag (owner or super-user only).
+[Directory is opaque when viewed through a union mount]
+.It Cm nodump
+set the nodump flag (owner or super-user only)
+.It Cm sappnd , sappend
+set the system append-only flag (super-user only)
+.It Cm schg , schange , simmutable
+set the system immutable flag (super-user only)
+.It Cm uappnd , uappend
+set the user append-only flag (owner or super-user only)
+.It Cm uchg , uchange , uimmutable
+set the user immutable flag (owner or super-user only)
+.It Cm hidden
+set the hidden flag
+[Hide item from GUI]
+.El
+.Pp
+Putting the letters
+.Dq Ar no
+before or removing the letters
+.Dq Ar no
+from a keyword causes the flag to be cleared.
+For example:
+.Pp
+.Bl -tag -offset indent -width "nouchg" -compact
+.It Ar nouchg
+clear the user immutable flag (owner or super-user only)
+.It Ar dump
+clear the nodump flag (owner or super-user only)
+.El
+.Pp
+Unless the
+.Fl H
+or
+.Fl L
+options are given,
+.Nm
+on a symbolic link always succeeds and has no effect.
+The
+.Fl H ,
+.Fl L
+and
+.Fl P
+options are ignored unless the
+.Fl R
+option is specified.
+In addition, these options override each other and the
+command's actions are determined by the last one specified.
+.Pp
+You can use "ls -lO" to see the flags of existing files.
+.Sh EXIT STATUS
+.Ex -std
+.Sh SEE ALSO
+.Xr ls 1 ,
+.Xr chflags 2 ,
+.Xr stat 2 ,
+.Xr fts 3 ,
+.Xr symlink 7
+.Sh HISTORY
+The
+.Nm
+command first appeared in
+.Bx 4.4 .
+.Sh BUGS
+Only a limited number of utilities are
+.Nm
+aware.
+Some of these tools include
+.Xr ls 1 ,
+.Xr cp 1 ,
+.Xr find 1 ,
+.Xr install 1 ,
+.Xr dump 8 ,
+and
+.Xr restore 8 .
+In particular a tool which is not currently
+.Nm
+aware is the
+.Xr pax 1
+utility.
