Forcing a Reboot (or Shutdown) with Linux
If you’ve ever had to reboot (or shutdown) a Linux system but the normal methods (reboot/shutdown/init) were not working (typically due to hanging processes) you can use the sysrq method instead: To reboot: echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger To shutdown: echo 1 > /proc/sys/kernel/sysrq echo b > /proc/sysrq-trigger
