Worked as stated just wanted to warm the CPU up after spilling small amount of tea on the keyboard! biggest yikes moment of my life, never drink next to a laptop... especially a macbook worth around £2000 I just tested my macbook pro retina.

Start one yes process per core (including hyperthreads) and use something like the Temperature Monitor app to see how hot the cpu gets over time. I have a hackintosh built with an i7-3770 and an aftermarket cooler, and I wanted to see how it performed. The i7-3770 has 4 cores and 4 hyperthreads, so I fired up 7 yes processes, then started the activity monitor to watch the cpu usage (88%, since I also had browsers open) and used Temperature Monitor to see how the cooler did.

There are other programs that have similar prompting behaviour. Oh, and "yes no | fsck" might sometimes be a good idea. I think yes dates back to Unix Edition 6. There are lots of programs that have little use by themselves but are designed specifically to be combined with something else. Unix is Lego for computers.

It's interesting in and of itself, but I don't see what real world use it actually has. I saw this elsewhere sometime ago, and wondered then what kind of practical application this could have.

You can measure the ability of the OS to start processes, but its not a measure of anything useful. You also don't need yes for this: "while :; do :; done &" is slightly more CPU intensive and does involve any system calls so it does nothing faster :) No, not really.

If you somehow timed how long it took to execute however many yeses? Just a thought. This could be used as a benchmarking tool of sorts couldn’t it?
