Dark Magic & Daemon Summoning with Bash Scripting

Starting teaching at college has been very rewarding; however, I still long for world domination like everyone else. I have encountered that teaching 30+ students is no easy task, and on top of that, marking? It ends up being time-consuming and a task that could be more enjoyable. But then I thought, "Hey, what about creating a script that helps me in my day-to-day life? After all, I'm a Dark Wizard with computing resources. Hell, I'll put those Daemons to work!" so I took on more digging on bash scripting! I already have basic knowledge and implement bash scripting on my RECON machine for Security Research. I will document my findings on Bash and the problems it helps me solve as I go with them. And ultimately build an army of scripts to help me achieve my goal of world domination! :)

Let's dig in!

Summon evil hell minions like a pro with Bash scripting!

Bash scripting is an essential component of system administration, automation, and computational workflows, all operating within the command-line interface domain. In this context, a "shell" serves as a mediator between the user and the underlying operating system, providing an intermediary platform or interface for interaction.

The Darks-Arts & it's Usage

Bash scripting is primarily used to automate sequences of system commands, perform administrative tasks, or orchestrate complex computing workflows. In essence, it allows the user to encapsulate a series of operations within a single script file, which enhances efficiency and makes tasks more repeatable.

Summon your First Bash Script

The inception of one's journey into Bash scripting commences with creating a script file, often denoted by a `.sh` extension. Within this file, the user orchestrates a sequence of shell commands, leveraging Bash's syntax and constructs to facilitate logical control flow.

For instance, consider the rudimentary "Dark Spell " script:

In this example, `#!/bin/bash` designates the interpreter, while `echo` renders the text "Let's summon black-magic automation!" to the terminal.

Permissions

File permissions, an imperative aspect of Bash scripting, proffer control over who can access and manipulate script files. Permissions are categorized into three distinct levels: user, group, and others, each delineating specific privileges encompassing read, write, and execute.

To modify permissions, the `chmod` command is invoked, followed by an octal digit that signifies the permissions. For instance, to grant execute permission to the user, the command assumes the form:

Executing

Execution of a Bash script is effectuated through the `./` prefix, which precedes the script filename, just like this:

Moreover, if the script has been endowed with execute permissions, it may be executed sans the `./` prefix:

Bash scripting is a powerful tool that can help system administrators automate tasks and streamline workflows. When used correctly, it can greatly enhance a user's ability to navigate complex computer systems and improve their overall skills. A few scripts on SMTP for emails, Cypress for grading and this will certanly help me clear my agenda for World Domination on Friday after lunch! :)
