=head1 SYNOPSIS

I<tabch [-h| --help]>

I<tabch [-v| --version]>

I<tabch [keycolname=keyvalue] [tablename.colname=newvalue] >

=head1 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.
