problem is that name of those nodes does not starts with "cab", it is in the middle. If you want to match any node that contains cab it will be different:

return $node->name imatch ".*cab.*";

This will match any name with letter combination cab at any position using regular expression. If you want something more complex you can use more complex regular expression. Site https://regex101.com/ is a good resource for testing your expressions.

i tried your script but nothing happened.

but how can i do for the ' pc-cab goes to template 'CAB' with a script
the script will be different no ?
sorry im so newbie about this ...

you can try this script:

p = substr($node->name, 1, 3);
return (p == "cab") || (p == "CAB");

This will add nodes with names starting with CAB or cab (but not Cab or caB). If case is actually not important at all you can use simply

return $node->name ilike "CAB*";
