The vendor will absolutely take that custom code and use it to extract maximum profit from a different customer. I’ve experienced it from both sides of the transaction. Open source at least allows the functionality to be “developed” only once.

It doesn’t even have to be offshore accounts. Just a fat long-term maintenance contract would be enough to hide a lot of corrupt costs.

800TB of bandwidth per month?

If you’re not already, use it as your main system. Don’t dual boot. Stop using windows and mac. When you run into something you need to do, figure out how to do it on linux. It will be slow going at first, but after a few months you will pick up more productivity than you had before.

Another commenter recommended the fish shell, but I disagree because fish is not posix compliant. Almost all of the shell script examples that you will find assume posix compatibility and will usually have to be modified to run with fish. Once you get comfortable with a posix-compliant shell, then maybe consider fish or another “modern” shell.

On the topic of shells, read the bash manual. It’s long and informative. You don’t have to memorize it, but be aware of the different concepts there, and refer to it when you need to. It’s pretty horrible as a programming language, but it’s what glues most of Linux together.

First, make sure it’s enabled in your kernel. Check the value in /proc/sys/kernel/sysrq to see if it’s enabled. Then see if you can trigger it by writing to /proc/sysrq-trigger. Then try an external keyboard that has real SysRq key. If all of those work, you may have to ask Framework support if their keyboard supports generating that keystroke.

The “Magic SysRq key” may be helpful as a last resort.

I succeeded in doing this once long ago. Then while in the Linux vm I wiped the VM’s partition table, which wiped the physical disk partition table, including windows. Do not recommend.
