SETEXTATTR(8)           OpenBSD System Manager's Manual          SETEXTATTR(8)

NAME
     setextattr - set a named extended attribute

SYNOPSIS
     setextattr attrnamespace attrname filename attrvalue

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

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

SEE ALSO
     extattr(2), extattr(3), extattrctl(8), getextattr(8), extattr(9)

HISTORY
     Extended attribute support was developed as part of the TrustedBSD Pro-
     ject.  It was developed to support security extensions requiring addi-
     tional labels to be associated with each file or directory.

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