AACC – Fall 2021 – CTS-233 – DevNet Associate: Linux CLI Tutorial 'pwd' and 'cd' Command Deep Dive

May 31, 2021

In this deep dive tutorial, created for my Anne Arundel Community College (AACC) CTS-233 DevNet Associate course learners, we take a comprehensive look at both the Linux ‘pwd’ and ‘cd’ commands and their various CLI options. We discuss the defaults of each built-in command and then dive into the Linux hierarchical filesystem and focus on the differences between relative and absolute pathnames and how to use the ‘.’ (dot) and the ‘..’ (dot dot) to optimize the CLI commands you are running when using commands like ‘ls’, ‘cd’, ‘cp’, and ‘rm’. Enjoy!

***This video is an in-depth tutorial and is far more than simply an answer key to the aforementioned Packet Tracer/Lab activity. This tutorial is being made to assist my AACC CTS-233 learners in their journey through the Cisco Networking Academy DevNet Associate course curriculum. So, if you are just looking for a shortcut or easy answers for the activity, this is not the video you should watch. However, if you are looking to gain a deeper understanding of the topic being covered and how things might be configured in a real-world scenario, my hope is that this will increase your comprehension and help you to become a better and more effective full-stack network administrator/engineer. Enjoy!

*This techtorial/Packet Tracer activity is all done running Cisco Modeling Labs (CML) v2.1.1-b19, some physical routers in my Evil Command Center Lab, and/or Packet Tracer version 8.0.0.0212 (for the Mac) which was just recently released! The MINIMUM version you can use for any of the new CCNAv7 curriculum activities is Packet Tracer v7.3.0, but I would upgrade to whatever the most current/latest version! For all Linux tutorials, I will be using an Ubuntu VM running in VMware Fusion on my iMac Pro. Be sure to leave your feedback and questions below and I hope I have earned the privilege of your time!
