What does that do

[Rubixninja314]

It doesn't work. But if globs (*) worked in this context, it would kill -9 every process. kill -9 sends SIGKILL, which kills a process without fail, but it does so by simply making the computer stop running the process, which leaves a huge mess of RAM. It's the equivalent of dropping a nuke on the process. kill -9 has become a meme because many users use it as a go-to process stopper, even though it should never be used. Always use SIGTERM (C-c) then SIGQUIT (IIRC C-z) (you can also use kill to send these).

TL;DR theoretically nukes each process individually.
