• init 6 command
• whoami command
• dmesg command
• w command 

 

EXPLANATION

dmesg (Display message or driver message) is a command which will show Kernel ring buffers. These messages contain valuable information about device drivers loaded into the kernel at the time of booting as well as when we connect a hardware to the system on the fly. In other words dmesg will give us details about hardware drivers connected to, disconnected from a machine and any errors when hardware driver is loaded into the kernel. These messages are helpful in diagnosing or debugging hardware and device driver issues
