=head1 DESCRIPTION
|
|
|
|
The B<chtab> command adds, deletes or updates the attribute values in the specified table.column for the specified I<keyvalue>. Normally, the given value will completely replace the current attribute value. But if "+=" is used instead of "=", the specified value will be appended to the comma separated list of attributes, if it is not already there.
|
|
|
|
The B<chtab> does not pass through xcatd, so it is not controlled by the policy mechanism.
