Reasons to Learn Bash Scripting

As of now, you have got a clear idea of how you can avail the course and be prepared to grab the impactful fundamentals and concepts. But, if you are a beginner with a minute idea upon bash scripting, then you might have questions like “Why Bash?” Moreover, to answer it all, here are some of the reasons to enlighten its efficacy:

  1. Popularity is Making It Pay More

Bash is the family of Linux command language interpreters. Therefore, it is known to be the 6th most preferred language amongst all. Moreover, the best part is that it ranks above R and Python. Therefore, with immense popularity, it is also destined to pay higher salaries than what people get with Python or R. This is referred to be based upon the Stack Overflow’s Developer Survey in the year 2020.

  1. Building Repeatable Processes

The skills and knowledge upon command line will be helping you build repeatable data processes. With it, you can ensure that your data is available regularly and conveniently, without time barriers. Command-Line is destined to suit the purpose because one can easily go for automating or replicating the commands.

  1. You Attain Flexibility

With Bash Scripting, you will be more flexible to use the terminals more often, rather than clicking upon GUIs. With Bash Scripting, you can ensure to have easy interaction between two programs within a command line. When you are proficient with the bash commands, you will find it quite easy to write or create scripts. With it, you can take a simpler approach towards building workflows and data pipelines.

  1. Bash is Not Much Resource-Intensive

Learning Bash and using the command line maximizes your speed when you lack computing resources. In such scenarios, where you need speed but have fewer resources, it is always recommended to use the command line instead of the GUIs. GUIs demand dedicated resources to render upon the graphical output. It doesn’t matter whether you work remotely or locally; GUIs intend to consume more of your bandwidth as compared to the terminals. Hence, they waste resources, while the command line implements less of them to give high functionality.
