=head1 DESCRIPTION
|
|
|
|
|
|
|
|
|
|
The nodegrpch command is similar to the nodech command, but ensures that the parameters are
|
|
|
|
|
declared at the group level rather than the node specific level, and clears conflicting node
|
|
|
|
|
specific overrides of the specified groups. Using table.column=value will do a
|
|
|
|
|
verbatim assignment. If ",=" is used instead of "=", the specified value will be prepended to the
|
|
|
|
|
attribute's comma separated list, if it is not already there. If "^=" is used, the specified
|
|
|
|
|
value will be removed from the attribute's comma separated list, if it is there. You can also
|
|
|
|
|
use "^=" and ",=" in the same command to essentially replace one item
|
|
|
|
|
in the list with another. (See the Examples section.)
|
|
|
|
|
|
|
|
|
|
With these operators in mind, the unambiguous assignment operator is '=@'. If you need, for example, to set
|
|
|
|
|
the nodehm.comments to =foo, you would have to do I<nodegrpch group1 nodehm.comments=@=foo>.
|
|
|
|
|
|
|
|
|
|
See the B<xcatdb> man page for an overview of each table.
|
|
|
|
|
|
|
|
|
|
The nodegrpch command also supports some short cut names as aliases to common attributes. See the
|
|
|
|
|
B<nodels> man page for details.
