DESCRIPTION¶

The tabch command adds, deletes or updates the attribute value in the specified table.column for the specified keyvalue. The difference between tabch and chtab is tabch runs as a plugin under the xcatd daemon. This give the additional security of being authorized by the daemon. 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 coma separated list of the attribute, if it is not already there.
