Useful bash scripts

by Mary Sewell

Linux, an operating system, requires some network commands that direct it to perform specific tasks or show certain details. Generally, the Linux powers we give to the operating system to act on the requested tasks are giving orders. These commands are typed in the Linux terminal and granted individually, consuming more time and comparatively tricky.

Bash scripting or Shell scripting is a programming system where we create a specific file, and on an orderly basis, we place one after the other Linux command; we recognize these commands in one single file. Then, the specific file is transformed into the form of scripts. Doing so allows us to easily activate or command our shell interpreters to execute the commands altogether.

Q.1 How are bash scripts useful?

A.1 Bash scripts are significantly used in tackling various essential tasks. These are useful for anyone working or operating a Linux system as an administrator. Being an admin means you must be quick at resolving hundreds of system-related issues. Knowing the commands is one thing, but using them fluently in the Linux terminal is another. These commands are often run one by one, whereas, being an admin, the operator must be efficient in running multiple orders simultaneously and in the same line. For this purpose, developers have devised ‘Bash scripting or Shell scripting. This method is beneficial as it makes the whole processing task smooth and fast. Through this, the admin can assemble the commands given to the system in a single file. This file is made into a script, and the orders are given out quickly.

A.2 Besides many other scripting processes, Bash Scripting, and Python Scripting benefit a DevOps engineer.

Bash Scripting Even today, many DevOps developers prefer to use shell scripting to develop various operating systems and software applications to run them efficiently per their needs or requirement. It has a very satisfying power and goes beyond its limitation to perform execution tasks.

Python Scripting Just as DevOps engineers prefer Bash Scripting, they also look at the wide range of usability attached to python scripting. This form of scripting comes with many uses, such as building cloud infrastructure projects, supporting various web applications, and efficiently be used for almost all purposes.
