RMEXTATTR(8)		  BSD System Manager's Manual		  RMEXTATTR(8)

NAME
     getextattr, lsextattr, rmextattr, setextattr -- manipulate	extended at-
     tributes

SYNOPSIS
     getextattr	[-fhqsx] attrnamespace attrname	filename ...
     lsextattr [-fhq] attrnamespace filename ...
     rmextattr [-fhq] attrnamespace attrname filename ...
     setextattr	[-fhnq]	attrnamespace attrname attrvalue filename ...

DESCRIPTION
     These utilities are user tools to manipulate the named extended at-
     tributes on files and directories.	 The attrnamespace argument should be
     the namespace of the attribute to retrieve: legal values are user and
     system.  The attrname argument should be the name of the attribute,
     filename the name of the target file or directory,	attrvalue a string to
     store in the attribute.

     The following options are available:

     -f	     (Force.)  Ignore errors on	individual filenames and continue with
	     the remaining arguments.

     -h	     (No follow.)  If the file is a symbolic link, perform the opera-
	     tion on the link itself rather than the file that the link	points
	     to.

     -n	     (NUL-terminate.)  NUL-terminate the extent	content	written	out.

     -q	     (Quiet.)  Do not print out	the pathname and suppress error	mes-
	     sages.

     -s	     (Stringify.)  Escape nonprinting characters and put quotes	around
	     the output.

     -x	     (Hex.)  Print the output in hexadecimal.

EXAMPLES
     setextattr	system md5 `md5	-q /boot/kernel/kernel`	/boot/kernel/kernel
     getextattr	system md5 /boot/kernel/kernel
     lsextattr system /boot/kernel/kernel
     rmextattr system md5 /boot/kernel/kernel

HISTORY
     Extended attribute	support	was developed as part of the TrustedBSD
     Project, and introduced in	FreeBSD	5.0.  It was developed to support se-
     curity extensions requiring additional labels to be associated with each
     file or directory.

BUGS
     The setextattr utility can	only be	used to	set attributes to strings.
