Used under [Linux] for Magic Sys Key. If you have this compiled into your kernel, *and* enabled in proc (see /etc/sysctl.conf or echo 1 >/proc/sys/kernel/sysrq) This means you can do nifty things even if your machine has completely screwed up. A useful sequence: ;Alt-SysReq-U:Force remount of all filesystems readonly ;Alt-SysReq-S:Sync all disks ;Alt-SysReq-B:Reboot Other useful commands: ;Alt-SysReq-?:List all sysreq's ;Alt-SysReq-K:Kill all processes --- CategoryKernel
