    And as always with this meme: Both Windows and Linux can ask a process nicely to terminate or kill it outright. And the default for both is to ask nicely.

      Well, with linux you get the option of sending mixed signals through the use of varying count of guns. I find 9 to be highly effective.

      on windows a process can get in a state so that it is impossible to make it go away, even with process explorer or process hacker. mostly this also involves the bugged software becoming unusable.

      I encounter such a situation from time to time. one way it could happen is if the USB controller has got in an invalid state, which one of my pendrives can semi-reliably reproduce. when that happens, any process attempting to deal with that device or its FS, even the built-in program to remove the drive letter, will stop working and hang as an unkillable process.

        Linux has that issue too. A process in an uninterruptible blocking syscall stays until that syscall finishes, which can be never if something weird’s going on.

        I’ve seen that on Linux as well. Funnily enough also with faulty file systems. I think NFS with spotty wifi for one.

        Oh, and once with a dying RAID controller. That was a pain in the ass. At that point I swore to only ever do RAID in software.

          oh yeah now that you say, SMB/CIFS mounted share if connection is no more. when I experienced this, it was temporary though, because there’s a timeout which is half (or double?) of the configurable reconnection timeout. but now that I think of it, I’m not sure if it made it unkillable.

          Add a -f to your umount and you can clear up those blocked processes. Sometimes you need to do it multiple times (seems like it maybe only unblocks one stuck process at a time).

          When you mount your NFS share you can add the “soft” option which will let those stuck calls timeout on their own.

      Because that’s better for the software, Linux however kills it outright when it doesn’t respond at all. Windows just… Waits. And you can’t really hardkill the processes from the task manager. Or at last my last knowledge is that.

        League of Legends captures and discards the ALT-F4 keystroke combination.

        Microsoft trusts app developers to use Microsoft’s standards (such as terminating the process when a close message is received) and they shouldn’t. App developers like Riot have taken advantage of this trust and tuned their apps to act differently than expected, and include code which makes the app minimize to the system tray instead, or force the user to answer questions (“Are you SURE you want to close?”), or do nothing at all.

        It should be punishable by death.

        You can easily make a program unkillable (or to be more precise untermable) on Linux. Here’s a simple bash script that will do that.

        #!/bin/bash                                                                                                     function finish {
          while true
          do                                                              
            echo "Can't kill me."                                   
            sleep 10                                        
          done                                            
        }                                                                                                               trap finish EXIT

        Taskkill /f is reasonably close to sudo kill -9

        Hitting the X in Windows and hitting the X in Linux both cause the application to start a save yourself routine. From the OS standpoint they’re not far off.

        The problem is we have a lot of confirmation bias in windows because every time we want to close an application that’s not working, that save yourself call has to sit around for a hellaciously long time out followed by a telemetry call so that Microsoft can track that it happened.

        It’s pretty rare that Linux apps don’t just close.

    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.

    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!

    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().

        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().

              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.

          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 555 which is upstream on most distros.

        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

            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.

                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.

                Get learning lol. I know that there’s some command line program that gives process info on mouse hover and then that can be parsed with awk to get the pid, then pipe that again into kill -kill. Then use xbindkeys or whatever keybindings program to bind that script to a key.

                Tbh. For involved stuff like this chatgpt will help you more than stackoverflow.

      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.
