===Purpose of Having a Matrix Account===
# 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 Putty application window will disappear.<br><br>
# It is recommended to repeat these steps with connecting to your Matrix account from a Seneca lab workstation until you become comfortable with the process.<br><br>
Note: If you are using a Apple Mac computer, or a computer running the Linux OS, refer to the procedures below to login to your Matrix account.
SSH from macOS:
#In a new Finder window
#Open: '''Applications''' > '''Utilities''' > '''Terminal'''
#On the command line, type: <span style="color:blue;font-weight:bold">ssh username@matrix.senecacollege.ca</span>
#Enter your password when prompted. Answer yes to any questions it may ask you.
SSH from Linux:
#Open up the "Terminal" (the command line).
#Choose '''Applications''' > '''System Tools''' > '''Terminal'''.
#On the command line, type: <span style="color:blue;font-weight:bold">ssh username@matrix.senecacollege.ca</span>
#Enter your password when prompted. You will not see the cursor move but you are indeed entering your password
In the next investigation, you will learn how to issue Linux commands and how to setup and perform the first two sections of the online ULI101 assignment #1.<br><br>
An '''argument''' can be a '''pathname''', '''text''', '''option''', etc.
An '''argument''' is <u>separated</u> from a command (or from other arguments) by a '''SPACE''', '''multiple spaces''' or a '''TAB'''.
For example:
# Type the following Linux command, but DON’T press the ENTER key: <span style="color:blue;font-weight:bold">cd /bin</span><br><br>
# Press the <span style="color:blue;font-weight:bold">ctrl-a</span> key combination. What happens?<br><br>
# Press the <span style="color:blue;font-weight:bold">alt-F</span> key combination (ESCOPTION+F right-arrow for Mac OSx). What happens?<br><br>
# Press the <span style="color:blue;font-weight:bold">ctrl-w</span> shortcut. What happens?<br><br>
# Type the following command: <span style="color:blue;font-weight:bold">ls</span><br><br>
<br>

Double-check your course timetable to confirm that this the correct section letter. If you have selected the WRONG section, type <span style="color:blue;font-weight:bold">C</span> in the menu selection area and press <span style="color:blue;font-weight:bold">ENTER</span>.

You are NOT required to complete all sections at the same time. You can check the assignment #1 link on the ULI101 main WIKI page to note the due date for assignment #1. Sections that are NOT completed will be displayed in '''reverse text with a blue background'''. On the other hand, when you compete a section, then the section will appear as regular text<br>(i.e not in reverse text).<br><br>[[Image:assn-sectioncompleted-completionwindow.png|thumb|right|250px|To confirm Main Assignment Window to Confirm Which Sections of Assignment Have or Have Not Been Completed. ]]</li><li>If you want to verify that you have completed sections for the assignment, look for the text '''"Marks earned so far for ULI101 Assignment:"''' and it will show how many sections have been completed.
