How does best practices in bash scripting work internally in Linux?

Best practices in bash scripting are essential for creating efficient, maintainable, and error-free scripts. These practices involve using consistent coding conventions, error checking, and comments to enhance readability and functionality. Internally, Linux processes these scripts through a series of steps including parsing, compiling, and executing commands in a shell environment.
