There are rust libraries to send signals, might be better to use those rather than calling bash. eg. https://docs.rs/nix/latest/nix/sys/signal/index.html

I'm guessing if input was "", then it would sigkill all processes? Less confident, but some functions behave slightly differently in an interactive console vs a non interactive, maybe ps has a different format when used non interactively?

Aside, you want three backticks and a newline to get code formatting :)

thx, btw I figured it out:

I forgot to trimm the string, so it had a line break in it which lead to grep showing the processes from the term I put in + all processes that contain a space/linebreak and appearently all processes shown by ps aux contain some kind of space (makes sense, since there are spaces between the user, pid, etc) so yeah, I ended up trying to kill every process on the system, but it only killed the user processes, since I ran everything without sudo
