List the DTrace providers in your machine

I don't see any official way to list the DTrace providers; you can seemingly only list ALL the probes, the >300K of them (in my Mac right now), and then you have to deal with the multitude of providers instantiated multiple times for different PIDs.

So here's a small AWK script to list the unique providers, how many instances of each are there, and how many providers are attached to each PID:

sudo dtrace -l |  gawk '
//  {        if($2 in provspids) {
            next
        }
        provspids[$2] = 1;
        provname = gensub(/[[:digit:]]+/, "", "g", $2);
        pid = gensub(/([^[:digit:]]+)([[:digit:]]*)/, "\\2", "g", $2);
        provs[provname]++;
        pid = strtonum(pid);
        pids[pid]++
    }
END {
        for (p in provs) {
            print p " x " provs[p];
            suminstances += provs[p];
            sumproviders++
        }
        print "\n\tproviders = " sumproviders ", provider instances = " suminstances "\n";
        for (pid in pids) {
            print "PID " pid " has " pids[pid] " providers"
        }
    }
'

 The sudo will ask for an admin password, but it's only needed to get the raw providers list.

An important detail: the providers without a PID in its name are attributed by the script to a non-existant PID 0, for ease of implementaiton. It's an ugly but useful special case for GAWK, since using purely numerical indexes in a GAWK array causes the array to be traversed in a sorted way – so we end up with a sorted PID list, which for us is perfect. There are other ways to do it, but right now I just want to cleanse this all with fire and get out of AWK. This has already taken like 10 times more than it should. When will I learn to just jump into Python?
