1. Linux normally does a nice shutdown as well, unless you force it.

2. You can force it on windows if you really want.

I'm so tired of linux memes posted/made by people who don't know much about windows or linux.

Linux gives processes a chance to gracefully close. However, it also will absolutely NOT allow a process to hang up the shutdown or restart procedure after a point. If you're using systemd (which there is a good chance you are), it'll count down. If the process hasn't stopped in the time allotted, it gets Old Yellered.

Linux does give every application time to shut down correctly, but unlike windows, it won't wait for ages until every process is down. Linux WILL shut down in a certain timeframe, whereas windows waits for years if necessary. In my old job, we all had to use windows and I had times where I clicked shut down, turned off my monitor, grabbed my stuff, left and in the next morning, the PC was still on because Notepad refused to just close lmao.

Is this even true? I am fairly sure that Linux also has a graceful shutdown process, but I'll admit I haven't looked into it.

If your app doesn’t respond to SIGTERM gracefully, you need to fix your app. The system did its job as documented.

I've never seen anything graceful in windows

i mean

Close correctly my ass, window's priority is to piss us off.

I feel this meme was created by someone who didn't actually know Windows in depth and recently learned of the kill command. Which by default just asks the process nicely to terminate itself.

Fear will keep them in line

Except Windows doesn’t. You can send WM_CLOSE, but that may not actually bail out of the core loop. PostQuitMessage() works better for some apps, but not at all for windowless CONSOLE subsystem processes. Windows also has a lot of special behavior around generating signals in other processes. It’s a mess.

Like, every time I reboot the reboot UI complains about mysterious, unnamed processes that take suspiciously long to quit.

Having the kernel yank the process out of existence with prejudice is definitely the way to go as apps should be hardened for crashing, anyway.

The kernel giveth, the kernel taketh away

If your code can’t handle a sig9 then your code is weak

Windows: Has a complex and graceful shutdown process to make sure programs never close if there's a problem with them and your computer just stalls on shutdown until you hold down the power button and completely void out the purpose of the graceful shutdown.

Don't both GNOME and KDE send sigterm first on shutdown?

kill commands make one feel like a Caesar

Linux is actually great if you need to implement graceful shutdown with signals -- I love it all around :)))

Closing correctly means the program stops NOW
