As you know already, my full name is Subin Siby. What’s special about my name is that it’s connected to Linux. As you may have seen, executable files on a Linux system is in the directory /usr/bin, /usr/sbin and /sbin. If you look at it closely, you can see that sbin only misses the character u from my name.
