Finding the current runlevel of linux

To find the current runlevel of the system we can use the following commands

$ who -r run-level 2 2012-08-28 19:43 last=

The output indicates that the current runlevel is "2" , followed by the date and the time. If there was any other runlevel used before it would be listed after "last=".
The second command that can be used is

$ runlevel N 2

The second number is the current runlevel. The first number is the previous runlevel.
