+.Sh NAME
+.Nm chflags
+.Nd change file flags
+.Sh SYNOPSIS
+.Nm chflags
+.Oo
+.Fl R
+.Op Fl H | Fl L | Fl P
+.Oc
+.Ar flags
+.Ar file ...
+.Sh DESCRIPTION
+The
+.Nm chflags
+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 Ds
+.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 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.
+.It Fl R
+Change the file flags for the file hierarchies rooted
+in the files instead of just the files themselves.
+.El
+.Pp
+Flags are a comma separated list of keywords.
+The following keywords are currently defined:
+.Bd -literal -offset indent compact
+.\"arch	nothing yet.
+dump	set the dump flag
+sappnd	set the system append-only flag (super-user only)
+schg	set the system immutable flag (super-user only)
+uappnd	set the user append-only flag (owner or super-user only)
+uchg	set the user immutable flag (owner or super-user only)
+.Ed
+.Pp
+Putting the letters
+.Dq no
+before an option causes the flag to be turned off.
+For example:
+.Bd -literal -offset indent compact
+nodump	the file should never be dumped
+.Ed
+.Pp
+Symbolic links do not have flags, so unless the
+.Fl H
+or
+.Fl L
+option is set,
+.Nm chflags
+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
+The
+.Nm chflags
+utility exits 0 on success, and >0 if an error occurs.
