Yes yes, I REALLY want to terminate that process and I am very sure about it too, ty.
Sigterm: “End this process or next time I bring my -9”
My tec-9
I feel like I’ve had the opposite experience in the gui (maybe a KDE issue?) closing gui windows frequently lock up, and I find I frequently have to drop to the command line in order to properly kill some programs
That’s because the end proces of the GUI sends a sigint, which does jack shit if the program hangs, you only archieve for a higher parent process to obtain it until it can off itself gracefully. You need to right click the process and send a sigkill signal to emulate the command line.
My problem with Windows is that when I want to eject a USB drive, Windows refuses to do so, refuses to tell me what program is apparently still using the drive, and certainly refuses to kill that program. I am removing the drive. I can’t just not remove it!
Okay, yes. This fucking sucks and it happens all the time on Windows.
The worst part is that with Quick Removal it’s pretty much always safe to just remove it
I’ve found that in those cases its usually explorer that’s the culprit. Just having the removable drive open in explorer is enough to keep windows from being able to unmount the drive.
At that point, you need to live dangerously and just yank it.
you forgot that you have to spend about 2 minutes with windows “searching for a solution” (who knows what that does??) and then another minute reporting it to microsoft
Skill issue.
TerminateProcess() is pretty reliable, but it doesn’t form part of the C signals stack on Windows like kill -9. So for instance, if you’re doing process control on Python, you need to use a special Windows-only API to access TerminateProcess().
Never used kill -9. What’s the difference between that and taskkill. I usually used taskkill /pid processiwanttokill.exe /f
Kill -9 is a command on Unix and Linux to send signal 9 (SIGKILL) to a process. That’s the version of kill that is the most reliable and has immediate effect.
Taskkill is a Windows command line program. I believe that taskkill /f uses the TerminateProcess() API. This is more forceful than the End Task button on the Task Manager. There is a different End Process button on the Task Manager that does use TerminateProcess().
Is the 9 pertaining to permissions like chmod uses them? I’ll have to look it up sometime. Been awhile since I’ve ever actually needed to force quit something in a Linux os
No, it’s just the number of a specific signal.
Thanks for that, I’ll have a ganter. Need to spin up a new VM soon and figure out a new distro to play with. Been slacking on exploring new things. Mostly only played with Yellow dog (small enough to dual boot on a PS3 with 512mb of ram back in the day), Ubuntu, Debian for other things. Likely will look for something that will work well for a media server.
Have fun exploring! I just have a simple Raspberry Pi at home with a few services, after working with this stuff all the time I rarely feel like tinkering at home :D
How the OOM Killer asks a process to terminate:
indiscriminate spraying
Is there some Linux equivalent to “ctrl + alt + del?” I get that killing a process from the terminal is preferred, but one of the few things I like about windows is if the GUI freezes up, I can pretty much always kill the process by pressing ctrl+alt+del and finding it in task manager. Using Linux if I don’t already have the terminal open there are plenty of times I’m just force restarting the computer because I don’t know what else to do.
Try ctrl+shift+ESC And remember, there are customizable hotkeys, just explore the settings
I’ve heard those quick keys a thousand times but my brain has determined that it is not necessary information for me to retain.
most distros have something, yeah, generally called [something] monitor
Ctrl+alt+F1/F2/F3 etc.
It lets you switch to another terminal session, where you can use something like top/htop for a commandline equivalent to task manager.That’s what I don’t get about what they said above. If the Windows desktop freezes up, Task Manager won’t open either (happened to me quite some times over the years - less so since they moved to the NT kernel though). What you mentioned always works short of kernel panic.
I’d say it’s been over a decade since I’ve had an issue where windows task manager didn’t work. Maybe I’m not using exciting enough programs.
ps aux | grep <process>. kill <pid>
killall
works great for this.At that point you can just hard restart as well. Most motherboards accept 10 to 15 seconds of power button as “my OS is fucked please help” and restart the machine for you.
They also accept pulling the power cord out as “oh no” and shutdown for you!
killall just kills all instances of a program, not everything.
and also, long pressing the power button should just shut it down, no?
kill -9 $(pidof <process>)
I’ve honestly not had this problem on windows since Windows 8.
btw funny story since many comments mention NFS/CIFS:
I have a share mounted at /smb and the server sometimes just dies so when I want to unmount it I run umount /smb but my shell (zsh) hangs after typing umount /sm and the b doesn’t even show
I guess zsh does a kind of stat() on everything you type but bash came to save the day
I don’t know if clean ZSH does it, but if you have the zsh-syntax-highlighting plugin, it tests if the path you’re typing exists every time you edit the line.
This is entirely wrong
Lol yes oh so wrong.
Wait until you find out about taskill /F /IM explore.exe
“Userid 1000 will shut down in 2 minutes”
Or whatever it says
I haven’t seen that in a while. When you see that it means either that the service didn’t handle the terminate signal correctly or that is is busy doing something. (Sometimes both)
I was just using it as an example against the 2nd image
Actually no, it’s just that the programs on Linux usually accept SIGINT, SIGTERM, etc pretty gracefully. Some are even smart enough to handle it on a thread hang. SIGKILL is last resort.
Lots of Windows applications like to ignore the close request because Windows doesn’t have signals and instead you can only pass a window name to request exit which is the same as clicking the close button.
So any hung software won’t respond and you have to terminate it.
both OS ask a process to end nicely? Then force closing in windows is with task manager or kill -9 in linux
It even kills threads currently executing a system call! The brutality!
Never even returned to userspace…
xkill
is one of my favorite commandsIs there a Wayland equivalent?
Open the process list in your system monitor of choice, right click, signal, sigkill.
You can also open a monitor and use top or any variant to detect the process number and manually
kill -KILL number
I really want the convenience of binding xkill to a key, which I can use to double tap programs like the undead zombie they’ve become.
Dunno, create a script that uses a program to get the process number of the current active window or the window the mouse is hovering, and then kill that? Bind that script inor a key with whatever program and voilá.
It’s more involved sure but there’s your option.
Great idea, now I just need to know how to do that.
What’s your desktop environment? I’m pretty sure hyperland and sway will give a json output of open Windows.
You could parse that with jq and pipe it into fzf or dmenu?
Not quite the same as the clicking but probably just as quick.
In whatever DE/WM you use, there should be an option to bind a key to run a command. You can bind a key to ‘sh -c xkill’ and it should do what you want.
I dunno; I sadly can’t use Wayland yet bc I have Nvidia
I don’t know if you heard, but the Nvidia issues are solved (mostly).
The issue most people had was with Explicit Sync, which was patched in the proprietary Nvidia driver x.55, which is upstream on most distros.
Good to know; I’ll check it out!
idk if this could be subjective, but what do you mean by upstream here? Does that mean it’s included in most distros?
