We type commands, and shell executes them in a beautiful and sophisticated way. Shell is also a super flexible programing language for Linux. It could bind commands together with conditions, loops and various expansions ($,~). Shell is actually a raw interpreting programming language. Raw interpreting means there is no compiled middle bytecode. In this post, I use <strong><code>bash</code></strong>, which is the most popular and widely deployed shell implementation.</p>
