I wanted to be able to easily see how many cores were reaching their turbo frequencies.
The problem with using watch grep \"cpu MHz\" /proc/cpuinfo is that it isn't easy to see that info, and for systems with lots of cores, the info wouldn't even fit in the terminal.
ftable [options]
-m <1000-9999> highlight frequencies above threshold
-n <SECS> seconds to wait between updates (Default: 2)
