Linux Force Reboot and Shutdown

Force Reboot :
echo 1 > /proc/sys/kernel/sysrq
echo b > /proc/sysrq-trigger
Force Shutdown:
echo 1 > /proc/sys/kernel/sysrq
echo o > /proc/sysrq-trigger
Better way of doing the about:
echo 1 > /proc/sys/kernel/sysrq
echo e > /proc/sysrq-trigger
echo i > /proc/sysrq-trigger
echo s > /proc/sysrq-trigger
echo s > /proc/sysrq-trigger
echo b > /proc/sysrq-trigger
