We Helped With This Programming Assignment: Have A Similar One?

Objective

This Flipped Learning (FL) challenge is to introduce you to the Linux command shell and some of its basic utilities.

Specific Objectives:

·         Use common Linux commands;

·         Work with files;

·         Learn the concept of the shell;

It is important to understand the command-line environment you are using to enter them. This command-line environment is known as the shell - a command interpreter, similar to the DOS prompt in Windows that allows you to type command, launch programs, and manipulate files.

The Bourne Again Shell (bash) is the most common shell installed with Linux distributions. When you login in, several things take place. The first of these is the launching of your shell, followed by the any configuration file you may have created for your personal Bash environment. Figure 1 shows the default shell application for Pi, LXTerminal.
