Using the Children Function

Even in a context with static children, it can be useful to iterate over those children programmatically. This can be done by using the children function, which returns an array of static children.

For example, here is a script that iterates over every service, printing out the status of the service:

configuration services
script
       var svcs = children();
       for (var i = 0; i < svcs.length; ++i) {
                run(svcs[i]);
                try {
                        printf("%-10s %s\n", svcs[i], get('<status>'));
                } catch (err) { }
                run("done");
       }

Here is the output of running the script, assuming it was saved to a file named svcinfo.aksh:
