Special Bash Variables with examples

Bash is a great coding language, which allows you to do complex things like Big Data Manipulation, or simply create sever or desktop management scripts. The entry level skill required to use the Bash language is quite low, and one-liner scripts (an often used jargon, which indicates multiple commands executed at the command line, forming a mini-script), as well as regular scripts, can grow in complexity (and how well written they are) as the Bash developer learns more.
