Bash Commands Guide

Update: January 5, 2020

Bash is an interactive command-line interpreter or shell. I would like to share the common usage of my shell commands and what they are. I have created this list for time-saving purposes. Because without GUI, all transaction moves faster without mouse usage.

This article is a guide for my next article — Bash Script Guide for iOS Developers, stay tuned for that!
