Hi,
I use unbound-control locally to reopen the log file after I rotate the logs using logrotate. The problem is that when unbound-control does contact the server and gets it to do what it wants, it prints “ok” on stdout.
This is annoying if you invoke it from within logrotate or a cron file. I know, I can add “>/dev/null” (this is what I did), but it is usually nice to have an option to tell any program to not output anything unless there is an error.
Using the attached patch, you use the “-q” (quiet) option so that unbound-control doesn’t print anything if everything went OK.
Since it’s been decades since the last time I seriously wrote C code, my patch is ugly (I don’t like it that it is a really inner function the one that prints the output and I don’t completely understand the argc/argv management within go() and go_cmd(), so I ended adding one more parameter in the functions.
Maybe someone who can actually code is able to do it right
