Add more shell Commands

[Yashvendra]

I've just added 4 commands to the shell. Adding extra commands like this will make it more realistic and useful.

Hello @mushrifshahreyar, to give you an idea i'm talking about adding more shell commands, sort of same what we have in normal linux terminal.
Try to be more specific what you want to know!
