Pure Bash Bible: A Comprehensive Guide to Bash Scripting

A brief introduction to the project:

The Pure Bash Bible is a comprehensive guide to Bash scripting, containing a collection of pure Bash alternatives to external processes. It is an open-source project hosted on GitHub and maintained by Dylan Araps. The project aims to provide a resource for developers to learn and improve their Bash scripting skills. By offering pure Bash alternatives to external processes, the project promotes script portability and supports systems that may not have certain utilities installed.

Mention the significance and relevance of the project:
Bash scripting is an essential skill for system administrators and developers managing Linux or Unix-based systems. Being able to automate tasks and write efficient scripts can greatly enhance productivity. However, many Bash scripts rely on external commands, which can limit their portability and lead to compatibility issues. The Pure Bash Bible solves this problem by providing pure Bash alternatives, making scripts more robust and independent of external dependencies.
