An interactive function to fuzzy search and kill processes:

Hey, nice to hear. Thanks!

I now have this function in my i3 config under the Ctrl-Space k
shortcut. This way I can kill a process from everywhere, even when I
am not in Emacs directly. I actually wanted to write something like
this for a while but kept postponing. Your function solves my issue.
Thanks again!

Is this Emacs in terminal mode and not GUI?

GUI, but should work with terminal too.

That looks very nice indeed.

If you can live without some fancy looks, this one does a similar job,
but is slightly simpler, and doesn't require proced, nor any other
library:

    (defun my-kill-process ()
      (interactive)
      (let* ((processes
              (remove-if-not
               (lambda (name)
                 (and (stringp name)
                      (not (string-match-p "root" name))
                      (string-match-p
                       (user-login-name) name)))
               (split-string
                (shell-command-to-string "ps -aux") "\n" t)))
             (process (completing-read "Kill: " processes nil t)))
        (shell-command-to-string (concat "kill -9 " (nth 1 (split-
string process))))))

I only do processes owned by my username here, so I skip sudo handling
here. It is actually really rare that I need to kill a process, so I
am fine with that. Output of last command is also ignored on purpose.

Can you kill emacs from emacs though

Only problem is that 95% of all the processes I ever need to kill are
emacs.
