    As someone who’s relatively new to Linux, anyone want to explain what these lines would do? I’m aware of KILL, but dunno what the ‘-9’ refers to. Not familiar with sysrq-trigger

      The kill command allows you to specify which type of kill signal you want to send. -9 sends signal 9 or SIGKILL, and we’re sending it to pid 1.

      That would force kill systemd, which I just have to assume will send your computer to a crashing halt.

      The echo command is writing "c" to a file at /proc/sysrq-trigger which I don’t really know how it works but this suggests you’ll “crash the system without first unmounting file systems or syncing disks attached to the system.”

      I haven’t installed fuck so I’m not sure how that works
