CHFLAGS(1)		FreeBSD	General	Commands Manual		    CHFLAGS(1)

     chflags --	change file flags

     chflags [-R [-H | -L | -P]] flags file ...

     The chflags utility modifies the file flags of the	listed files as	speci-
     fied by the flags operand.

     The options are as	follows:

     -H	     If	the -R option is specified, symbolic links on the command line
	     are followed.  (Symbolic links encountered	in the tree traversal
	     are not followed.)

     -L	     If	the -R option is specified, all	symbolic links are followed.

     -P	     If	the -R option is specified, no symbolic	links are followed.
	     This is the default.

     -R	     Change the	file flags for the file	hierarchies rooted in the
	     files instead of just the files themselves.

     The flags are specified as	an octal number	or a comma separated list of
     keywords.	The following keywords are currently defined:

	   arch	   set the archived flag (super-user only)
	   opaque  set the opaque flag (owner or super-user only)
	   nodump  set the nodump flag (owner or super-user only)
	   sappnd  set the system append-only flag (super-user only)
	   schg	   set the system immutable flag (super-user only)
	   sunlnk  set the system undeletable 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)
	   uunlnk  set the user	undeletable flag (owner	or super-user only)
	   archived, sappend, schange, simmutable, uappend, uchange,
		   uimmutable, sunlink,	uunlink
		   aliases for the above

     Putting the letters ``no''	before an option causes	the flag to be turned
     off.  For example:

	   nouchg  the immutable bit should be cleared

     Symbolic links do not have	flags, so unless the -H	or -L option is	set,
     chflags on	a symbolic link	always succeeds	and has	no effect.  The	-H, -L
     and -P options are	ignored	unless the -R option is	specified.  In addi-
     tion, these options override each other and the command's actions are
     determined	by the last one	specified.

     You can use "ls -lo" to see the flags of existing files.

     The chflags utility exits 0 on success, and >0 if an error	occurs.

     ls(1), chflags(2),	stat(2), fts(3), symlink(7)

     The chflags command first appeared	in 4.4BSD.
