Answer #1

w is the command used to find who are online and what they are doing.

Here the content of line 3 of the w command is what we need here.

w x0r_d3v1l | awk 'NR==3'

Here x0r_d3v1l is user in this case.

Here the output of the command w x0r_d3v1l is piped to awk and NR is used to keep the current count of the record which is in general line. Here we need the line 3 of the command w hence we are checking with NR==3.

The output of the command may change from at your system as it depends on the current usage,uptime etc.

xor_d3vil@msi:-$ w 00:14:09 up 16 min, 1 user, load average: 0.95, 1.12, 1.13 USER TTY FROM LOGIN@ IDLE JCPU PCPU WHAT xor_d3
