.Sh DESCRIPTION
|
|
.Nm
|
|
is a user tool to set a named extended attribute on a file or directory to
|
|
the provided string.
|
|
The
|
|
.Ar attrname
|
|
argument should be the name of the attribute,
|
|
.Ar filename
|
|
the name of the file or directory to set the attribute for, and
|
|
.Ar attrvalue
|
|
a string to store in the attribute.
|
|
.Nm
|
|
will store the string in the file's attribute.
|
|
In order for
|
|
.Nm
|
|
to succeed, the attribute service must be available on the file system,
|
|
and appropriate privilege may be required.
|
|
