     setextattr - set a named extended attribute

SYNOPSIS    [Toc]    [Back]

     setextattr attrnamespace attrname filename attrvalue

DESCRIPTION    [Toc]    [Back]

     setextattr is a user tool to set a named extended  attribute
on a file or
     directory  to  the provided string.  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 file or directory to  set  the  attribute for, and
     attrvalue  a  string  to store in the attribute.  setextattr
will store the
     string in the file's attribute.  In order for setextattr  to
succeed, the
     attribute  service must be available on the file system, and
appropriate
     privilege may be required.

EXAMPLES    [Toc]    [Back]

           # setextattr system md5 /bsd `md5 < /bsd`

     Set the ``md5'' extended attribute on the file /bsd  to  the
string containing
 the output of ``md5 < /bsd''.
