You know, that's what I had the first time through, but then I collapsed it into a single statement thinking the temp variable was messy. :) It'd sure be handy if Cfengine could determine whether the last argument was the name of a list or a literal list in things like join and grep. That's been one of the challenges in learning the language; sometimes, to pass a list use "@(listname)," while other places use "listname". It seems like, if the functions used (or supported) the @(listname) mechanism, then the structure I used above would probably also work more like I'd expect. But I'm probably just disoriented because most other languages don't ever ask for the name of a variable, but rather the contents or the location of the contents. :) _______________________________________________ Help-cfengine mailing list Help-cfengine@cfengine.org https://cfengine.org/mailman/listinfo/help-cfengine
