Frequently Asked Question
Shell scripting is a way of writing scripts or programs that are executed in a terminal or shell. A shell is a special user program that provides an interface for the user to use operating system services. It accepts human-readable commands from users and converts them into something which the kernel can understand.
Some of the most commonly used shell commands include ls, cd, mkdir, rm, cp, mv, cat, grep, and echo .
Linux is a popular operating system because it is open-source, highly secure, and offers a lot of customization options, making it ideal for both personal and professional use.
Linux has long been hailed as the more secure of the two OSs, but some believe Windows is catching up. Windows Defender’s improved reputation for blocking viruses, Trojans, and other malicious software is a good sign. But even so, Windows has a deeply embedded design flaw keeping it from catching up to Linux.
The answer here is both yes and no. Linux is easier to learn than Windows, but not necessarily easier to work with. It all depends on the tasks you want to perform. Linux is easier to use for programming, performing administration tasks, and regulating your system’s resource density.
In terms of speed, Linux runs faster than the Windows operating system, especially on moderately powerful systems, while the Windows operating system starts becoming slower with time. Windows collects data regularly to enhance the consumer experience, while Linux refrains from doing so.
Python is one of many programming languages available to you. For network automation today, I firmly believe that Python is the de facto standard with the widest range of modules to help you in your automation pursuits. It has already been pointed out that Python runs on many operating systems, including Linux.
Linux-based laptops are also great for high school and college students looking to expand their knowledge and skillsets. Linux is also able to be run on many readily-available Windows laptops, often in tandem, which is great for beginners who may not be ready to invest in a dedicated machine.
Writing shell scripts leaves a lot of room to make mistakes, in ways that will cause your scripts to break on certain input, or (if some input is untrusted) open up security vulnerabilities.
That probably means a shell script, and for most people, that probably means using Bash (or something like it). Bash, coupled with the usual suite of Linux command line tools, is fantastically powerful and adaptable.
