Title: Competency 1 Introduction
Course: UNIX Operating System I (13673) > Section: Competency Modules

For Unix/Linux OS I, a student needs to have the five following skills related to commands and utilities:

1. How to type a syntactically correct command on the Linux command line, because the predominant mode of interaction with the LInux system is text-based.
2. How to log in to and log out of a computer running Linux using one of the standard methods. Linux allows users to enter the operating system autonomously, construct code by keystrokes, and exit gracefully.
3. How to maintain and organize files. Creating a tree-like structure of folders (also called directories ), and storing files in a logical fashion in these folders, is a critical role to working efficiently in LInux.
4. How to get help on commands and their usage. In a command-based environment, being able to find out, in a quick and easy way, how to use a command correctly is imperative to working efficiently.
5. How to execute a small set of essential utility commands to set up or customize your working environment. Once a beginner is familiar with the right way to construct file maintenance commands, adding a set of utility commands  makes each session more productive.
