[[Image:cli-prompt.png|thumb|right|120px|A '''shell''' is an interface / interpreter to allow a user to communicate with the Linux computer system. ]]
Although you need to study concepts throughout this course (slides, etc.), you will also need to get '''hands-on practice running Linux commands as well as performing and submitting online tutorials'''.
This requires that you '''connect to a Linux server''' (Matrix) and become comfortable '''issuing Linux commands'''.
In this labUnix/Linux, you a '''shell''' is simply an '''interface''' to allow a user to communicate with the Linux computer system (server). Linux shells have evolved (improved) over a period of time. You will learn be using the '''Bash Shell''' which is considered to be ''user-friendly''. By understanding how to install your issue Linux commands, you can create a file that contains Linux commands (called a '''CentOS Full Install DVDshell script''' as ) later in this course to automate tasks to make you a virtual machine using the more '''VMware Workstationproductive''' applicationLinux user and system administrator.

The '''Matrix server''' consists of '''several computers connected together''' to form a '''cluster'''.<br>A '''Linux cluster''' is a '''cost effective''' alternative to buying larger servers.
All registered students in this course should have an account on the Matrix server.<br>You will be using this account for the following reasons:
:* Issuing '''Linux commands'''
:* Becoming productive using the Linux '''command prompt''' ('''shell''')
:* Performing '''Linux Tutorials''' ('''11 Weekly Tutorials x 2% = 22% of your final grade''')
:* Performing '''Linux Practice Questions'''
:* Performing '''Review Tutorial''' ('''8 Sections x 1% = 8% of your final grade''')
===Connecting to the Seneca Student VPN===[[Image:gp1.png|thumb|right|130px|'''<u>c7host VM Details:</u>Seneca Student VPN''']]
:After connecting to the '''Seneca Student VPN''', you can open a '''command terminal''' in '''Windows 10 (or above)''', '''Mac''' or '''Linux''' computer and issue the following command:
: <span style="color:blue;font-weight:bold;">ssh senecauserid@matrix.senecacollege.ca</span>

'''ALT-CTRL'''Perform the Following Steps:Return focus from your c7host VM to your '''host computer system'''.
# Click on the '''Edit''' menu item, and then select '''Settings''' in the Edit drop-down menu.<br><br>
# To change the size of your shell window, under the ''Global Settings'' section, click '''Appearance'''<br><br>
# Change the ''window size'' both horizontal and vertical to larger values.<br><br>
# To change the font size, under the ''Global Settings'' section, click '''Font'''<br><br>
# Select a larger ''font size'' and click '''OK'''<br><br>
# You now should notice that you have customized your SSH shell terminal. You can use the settings screen to also change your background and text colours if you are interested in doing so.<br><br>
# To exit your Matrix session, type the following command and press ENTER: <span style="color:blue;font-weight:bold">exit</span><br><br>'''NOTE:''' You should notice that the colour of the text changes slightly when disconnected and you are unable to issue Linux commands from that window.<br><br>

=INVESTIGATION 2:* Faster GraphicsUSING THE LINUX SHELL =:* Allow applications running in a VM In this investigation, you will learn how to be accessed use the Linux Shell. Topics in the host machine (unity interface):* Sharing folders between host and VM:* Copying and pasting text between host and among VMssection include:* Clock synchronization among host and VMs
==Linux Command Structure==
The Bash shell allows you to interact with Linux by typing commands.

'''To Disable the Locked Screen-saver, Perform the following steps:What is an argument?'''
An '''argument''' <u>must be separated</u> from a command (and from other arguments) by whitespace (a '''SPACE''', '''MULTIPLE SPACES''' or a '''TAB''').
# Confirm that you are logged into your Matrix account.# Issue the following Linux command: <span style="font-family:courier;color:blue;font-weight:bold">pwd</span>#* '''Explanation:''' The output from this Linux command shows your '''current location'''Perform on the Matrix server (otherwise known as your '''p'''resent '''w'''orking '''d'''irectory). This represents a '''directory pathname''' to your home directory.

This is called metadata (data about data), and includes information such as last modified date, file size, ownership and permissions.# Return to your home directory: <span style="font-family:courier;color:blue;font-weight:bold">cd</span># Now confirm you've changed back to your home directory: <span style="font-family:courier;color:blue;font-weight:bold">pwd</span>#* '''Result:''' The shell should display <code>/home/''yourusername''</code># Issue the following Linux command: <span style="font-family:courier;color:blue;font-weight:bold">ls /bin</span># Issue the following Linux command to confirm your current location: <span style="font-family:courier;color:blue;font-weight:bold">pwd</span>#* '''Question:''' What do you notice?#* '''Question:''' What makes this command with that argument useful if you are currently located in your home directory?# Issue the following Linux command:<span style="font-family:courier;color:blue;font-weight:bold">clear</span>#* '''Question:''' What do you notice?

It won't display all users logged into the cluster, only the ones on the same node as you. # Issue the following Linux command: <span style="color:blue;font-weight:bold">whoami</span>#* '''Question:''' What does this command display?#* '''Question:''' What do you think is the purpose of this command?# Issue the following Linux command: <span style="font-family:courier;color:blue;font-weight:bold">cal</span>#* '''Question:''' What does this command do?# Issue the following Linux command: <span style="font-family:courier;color:blue;font-weight:bold">cal 2035</span>#* '''Question:''' How and why is the output different?# Issue the following Linux command: <span style="font-family:courier;color:blue;font-weight:bold">cal 2 2035</span>#* '''Question:''' What do each of these numbers do?#* '''Question:''' What do you think would happen if you reversed the order of those arguments? (i.e. cal 2035 2)
If you have correctly completed the required tasks, the user can proceed. If the checking shell script detects an '''error''', then it will provide feedback to allow the student to fix that problem so they can re-run the checking shell scripts until they have successfully completed a task.
