For example, if your Seneca user ID was '''mkhan''' then you would display the pathname ''/home/your-seneca-id'' as: '''/home/mkhan'''
# '''Login''' to your matrix account (you should know how to do this from performing [https://wiki.cdot.senecacollege.ca/wiki/Tutorial_1:_Using_Your_Matrix_Server_Account#INVESTIGATION_1:_ACCESSING_YOUR_MATRIX_LINUX_ACCOUNT Tutorial 1 INVESTIGATION 1]]).<br><br>
# Issue a command to '''confirm''' that you are located in your home directory<br>(you should know how to do this from performing [https://wiki.cdot.senecacollege.ca/wiki/Tutorial_1:_Using_Your_Matrix_Server_Account#INVESTIGATION_2:_USING_THE_LINUX_SHELL Tutorial 1 INVESTIGATION 2]<br><br>
# Issue the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">mkdir /home/your-seneca-id/uli101xx</span><br>(remember: use <u>your</u> Seneca username instead of "your-seneca-id")<br><br>'''NOTE:''' You should always confirm that you have created a directory.<br>This can be done by issuing the '''ls''' command.<br><br>[[Image:directory-structure-4.png|thumb|right|350px|'''Creating''' and '''Confirming''' the Creation of a Directory.]]
