• Basic Linux Commands: I also got familiar with the linux shell some basic commands like cp=copy, mv = move, rm = remove/delete, sudo = superuser permissions ,pwd = present working directory etc.

• In a script file first type "!#" schebang tells the system to use the a interpreter "!#/bin/bash" this tells the interpreter that a shell script should be executed using the Bash shell interpreter
• Automation with Shell Scripts: I already knew python so for me scripting looked a simple I used for loops to to add multiple users . Also created a automated script to update system , to install tools according to input received by the users.
