Load the Linux Journey website, and navigate to the Command Line instruction module.
Today we will walk through the Command Line online instruction module together, investigating a number of important commands used to navigate and perform actions within the Linux shell.
Visit JSLinux to see a fully-featured Linux shell running a JavaScript-based emulator. This also provides us a very useful platform for practicing CLI commands.
Input the commands described in the module, and observe their output:
echo
pwd
cd
ls
touch
file
cat
less
history
cp
mv
mkdir
rm
find
help
man
whatis
alias
exit
Once you’ve got the hang of these basics, we’ll explore more complex commands in tomorrow’s module. Be prepared to use these commands in a brief Check for Understanding quiz on Friday.

Students will begin preparing for proficiency in cyber security and information security techniques, technologies and methodologies by learning the basics of the Linux operating system.
The first step on our journey to Cybersecurity proficiency is to gain proficiency in the Linux operating system. A large portion of the systems that run the Internet run on a variant of Linux, and therefore learning how to effectively use the Linux command line will be a necessary step towards gaining this proficiency.
We will begin by visiting the Linux Journey website, and we will walk through the online instruction modules together, learning about the history of Linux, and working our way through a few of the various distributions of Linux, noting the unique features of each and exploring the advantages and disadvantages presented by each flavor of Linux.
Tomorrow, we will begin working with the Command Line Interface in Linux, and investigate a few important commands.

Capture packets on your eth0 interface for a period of five minutes. Visit https://netop.mistermarmolejo.com to get some http traffic going during the packet capture.
Save the packet capture as a .pcapng file with today’s date, and upload it to today’s assignment post on Google Classroom to complete the activity by end of day tomorrow.
Today we will start working with Wireshark – a powerful packet collection and analysis tool that is free to download and pre-installed in the Kali Linux distribution.
We will be using this and other videos to gain a familiarity with the Wireshark environment, and look at the methods and construction of network packets, so we can begin to develop “the eye” for packet formation and transmission anomalies.
