Although you need to study concepts throughout this course (slides, etc.) throughout this course, you will also need to get '''hands-on practice running Linux commands as well as performing online tutorials and performing and submitting online course assignmentstutorials'''.<br>This requires that you '''connect to a Linux server''' and become comfortable with '''issuing Linux commands'''.
In Unix/Linux, 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 be using the '''Bash Shell''' which is considered to be ''user-friendly''. By understanding how to issue Linux commands, you can create a file that contains Linux commands (called a '''shell script''') later in this course to automate tasks to make you a more '''productive''' Linux user and system administrator.

===Connecting to the Seneca Global PortalStudent VPN===[[Image:gp1.png|thumb|right|130px|'''Seneca Global PortalStudent VPN''' ]]
Seneca College is "rolling-out" additional measures to improve '''network security'''. One of these measures<br>is to implement '''multi-factored authentication'''. As of '''September 2020''', all Seneca College students are required<br>to connect to the '''Seneca Global PortalStudent VPN''' in order to be able to connect to their '''Matrix''' Linux account.<br><br>''<b>Multi-factor authentication</b> is an electronic authentication method in which a computer user is granted access to a website or application only after successfully presenting two or more pieces of evidence (or factors) to an authentication mechanism: knowledge (something the user and only the user knows).'' Reference: https://en.wikipedia.org/wiki/Multi-factor_authentication<br><br>You should have received an email message (also available in course announcements) regarding how to setup your Smart Phone to connect and valid via the Seneca Global PortalStudent VPN. '''NOTE:''' If you haven't done this yet, please perform the steps provided in the following link:<br>https://employeesstudents.senecacollege.ca/spaces/77186/it-services/wiki/view/37221025/student-vpn<br><br>
In the next investigation, you will learn how to '''connect''' to and '''login''' to your Matrix server account from a remote computer<br>such as your '''home desktop computer''', '''laptop''' or '''tablet''' computer.<br><br>
===Connecting to Your Matrix Account===
:* From your '''NOTE:home computer''' Although you can install and run the AppsAnywhere application on an Apple Mac computer, you will NOT have access to many of the Windows applications (including applications to connect to your Matrix account). In this case, you can open <br>:* From a '''terminalworkstation in a Seneca College''' and issue the lab via '''sshMyApps''' command to connect to your Matrix account.
===METHOD 1: CONNECTING TO YOUR MATRIX ACCOUNT FROM A COMMAND LINE TERMINALYOUR HOME COMPUTER===
[[Image:gp1.png|thumb|right|130px|The '''Global PortalSeneca Student VPN''' service must be connected.]]

<br>
In this sectioninvestigation, you will learn how to use the Linux Shell. Topics in the section include:
:* Learn the basic '''Linux command structure''' (''arguments'' and ''options'')
:* Learn how to get '''help''' for Linux commands via the '''online manual''' (i.e. '''man''' command).
:* Perform '''Basic Shell Editing'''
:* Learn how to setup Issue a '''online assignment 1program'''.:* Perform the '''first section''' and '''3 parts of the second section''' of online assignment #1'''.to confirm that you connected to your Matrix account<br><br> ===Part 1: Using the Linux Shell ===
The Bash shell in Matrix allows you to interact with your Matrix account by issuing commands.
An '''argument''' can respresent:
:* a '''file pathname'''
:* a command '''option'''
:* a series of characters (i.e. '''text''') that the command can use
# Issue the following Linux command to return to your home directory: <span style="font-family:courier;color:blue;font-weight:bold">cd</span><br><br>
# Issue the following Linux command to confirm your current location: <span style="font-family:courier;color:blue;font-weight:bold">pwd</span><br><br>
# Issue the following Linux command: <span style="font-family:courier;color:blue;font-weight:bold">ls /bin</span><br><br> # Issue the following Linux command to confirm your current location: <span style="font-family:courier;color:blue;font-weight:bold">pwd</span><br><br>What do you notice? <br><br>What makes this command with that argument useful if you are current located in your home directory?<br><br># Issue a Linux command that you have already learned to change to your '''home''' directory<br>and to '''confirm ''' that you have returned to your home directory.<br><br>

'''Getting Help with Linux Commands'''
With the Linux OS containing over '''2500''' commands and utilities, it is good for a Linux user or <br>Linux system administrator (sysadmin ) to learn about how to use commands “on-the-fly”.<br><br>
The '''man''' command can provide information on how to use a command<br>(i.e. '''command usage''', '''acceptable command arguments''', '''command options''', '''examples''').<br><br>
# Issue the following command: <span style="font-family:courier;color:blue;font-weight:bold">man man</span><br><br>You may notice that the online manual categories commands into sections or '''numbered volumes'''.<br><br>
# Navigate through the man utility for the '''ls''' Linux command and note the '''option letters''' that correspond to the following descriptions:<br><ul><li>"'''use a long lising format'''"</li><li>"'''do not ignore entries starting with .'''" (i.e. hidden files)</li><li>"'''sort by file size'''"</li><li>"'''append indicator (one of */=>&|) to entries'''" (i.e. type of file)</li></ul><br>
# Exit the man utility for the ''ls'' command.<br><br>
# Issue the '''ls''' command for <u>each</u> of those option letters you noted in '''step 45''' to see how this command differs for each option.<br><br>'''NOTE:''' The '''man''' utility can be used with the '''-k''' option to help list Linux commands that match a text pattern<br>that is contained within the help screen for a Linux command.<br><br>
# '''Pipeline commands''' can be used to filter-out unnecessary output. In the next command that you will be issuing,<br>the output from the '''man -k''' command, is sent into the '''grep''' command to ''filter'' (i.e. ''trap'') only output that matches the pattern "8"<br>(The number "8" refers to the category of type of command - in this case, administration commands).<br><br>We will learn more about pipeline commands later in this course.<br><br>
# Issue the following Linux pipeline command: <span style="font-family:courier;color:blue;font-weight:bold">man -k user | grep 8</span><br><br>How does this ''pipeline command'' make it easier to obtain information regarding man command?<br><br>
# If you wish to change your password, you can change it by issuing the command: <span style="font-family:courier;color:blue;font-weight:bold">passwd</span><br>What option for the passwd command can be used to change user info (such as name)?<br>'''Hint:''' use the '''man''' command for '''passwd'''.<br><br># Press the letter <span style="font-family:courier;color:blue;font-weight:bold">q</span> to exit the man command.<br><br>'''NOTE:''' Do '''NOT''' run the ''passwd'' command.

What is the advantage of using '''ctrl-u''' as opposed to '''ctrl-l'''?<br><br>:The Bash shortcut keys that you just learned are sufficient to perform Bash Shell editing.<br>Although you are NOT required to learn other short-cut keys, here is a link to a listing in case you are interested:<br>[https://ostechnix.com/list-useful-bash-keyboard-shortcuts/Useful Bash Shell Keyboard Shortcuts]<br><br>'''Running a Shell Script to Check Student Online Tutorial Participation''' Professors will require students successfully perform these online tutorials for marks (within a deadline). <br>In order to confirm that you successfully performed a tutorial, you will be required to run a program<br>(or in later tutorials, several programs) to prove that you successfully completed tasks in a tutorial and get marks. These programs (known as Shell Scripts) will check your work and offer feedback if you made mistakes, so you can make corrections.<br>Making corrections (i.e. troubleshooting) and re-running these checking programs until you are successful will help students<br>gain "hands-on" experience as well as "trouble-shooting experience. <table align="right"><tr valign="top"><td>[[Image:script-check-1.png|thumb|right|250px|If all all check pass, then user performed can proceed.]]</td><td>[[Image:script-check-2.png|thumb|right|450px|If there is a warning, then feedback is provided to user to correct and re-run checking script.]]</td></table>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.
