To kill all the processes that you have the permission to kill, simply run the command
kill -15 -1 or kill -9 -1 depending on the desired behavior (use man kill for details)

If you want to see what processes are running use the command
ps -ef
If you want to look up all processes by user bob, this might help
pgrep -l -u bob
or
ps -ef | grep bob

Best way to effectively kill a process?
There are only two signals (what you called "sub-command" in the comments) that can't be trapped (i.e. ignored by a process) -- SIGSTOP and SIGKILL, generally SIGKILL is used to kill an unresponsive process, e.g kill -9 ${process_pid} or kill -s KILL ${process_pid}. p.s. if you don't specify a signal, by default kill sends the SIGTERM signal, which can be ignored by a process.

How To Kill Process in Linux & Terminate a Process in UNIX - nixCraft
May 6, 2026 - It is the default and safest way to kill process. The kill and killall command support more than 60 signals. However, most users only need to use signal 9 or 15. To get a full list of signals, type the following kill command with -l: $ kill -l Here is what I see: First, try to send SIGTERM (15) and if that failed then only try the SIGKILL (9) signal. A Linux or Unix process is running instance of a program.

January 16, 2024 -
There are different options to kill a proces like hangup, terminate or interrupt (to name a few) but which one is the most effective way of killing a process? Like is there a command with which you can eliminate nasty hard-frozen processes? Sorry if this question sounds dumb, I am just unsure on all the different kill-options and wanted to know the real difference between for example hangup and interrupt - thanks in advance! :)

A shotgun to the CPU.. In all seriousness, it depends. Processes can implement different signal handlers for certain signals, and it might be unwise to go nuclear immediately. SIGKILL is probably the most effective. But it can still leave zombies.

use the following command to display the port and PID of the process:
sudo netstat -plten
AND THEN
kill -9 PID
Here is an example to kill a process running on port 8283 and has PID=25334

Instead of this:
proid= pidof $proceso
You probably meant this:
proid=$(pidof $proceso)
Even so,
the program might not get killed.
By default, kill PID sends the TERM signal to the specified process,
giving it a chance to shut down in an orderly manner,
for example clean up resources it's using.
The strongest signal to send a process to kill without graceful cleanup is KILL, using kill -KILL PID or kill -9 PID.
I believe it's some kind of problem with the bash language (which I just started learning).
The original line you posted, proid= pidof $proceso should raise an error,
and Bash would print an error message about it.
Debugging problems starts by reading and understanding the error messages the software is trying to tell you.
