Here comes the power of shell scripting, with the presence of the powerful built in command line tools in linux, that task could be done very easily with a simple script that could save you a lot of time So a very common question might be “when do i use bash and why”, to answer this let’s consider this real life scenario, you’re an ethical hacker / pentester and you were tasked to scan a network for a specific service running ( let’s say ssh } and try to brute force into that with default credentials, how do you plan on doing that MANUALLY ? Powershell : Windows based shell environment.zsh : also another shell environment in many Linux distros.Python : yes the programming language, it also has an interactive python shell which means it only runs Python commands.In that sense, a shell is an environment to run commands directly instead of the traditional GUI way of clicking and dragging stuff and like i said that’s a huge advantage for automation and productivity Think of an environment this way, MS PowerPoint is an environment to produce and display presentation slides, for example you can’t view those slides inside another software like the calculator So a shell is a utility that allows us to directly interact with the kernel through issuing commands and it’s considered a very powerful tool and this shell comes in “flavors” that act as environments
