=INVESTIGATION 1: CREATING & MANAGING DIRECTORIES=
In this investigation, you will learn how to '''create''', '''navigate''', '''list directory contents''' and '''remove''' directories in your Matrix account.
'''Directory File Naming Rules'''
* '''Avoid non-alphanumeric characters''', as they may have a special meaning to the system that will make your work more difficult when changing to directories, etc.
* '''Avoid using spaces''' for directory names (consider periods, hyphens, and underscores instead)
===Part 1: Creating Directories ===
[[Image:directory-structure-3.png|thumb|right|350px|'''Tree Diagram''' of Directory Structure to Create in your '''Home''' Directory (displayed in blue text).]]
Creating subdirectories within your home directory makes it more '''efficient''' to<br>save and access files on your Linux server.
A comparison would be rooms in a '''house'''. If there were no rooms, just one large room in a 3,000 square foot house, it would be "messy" and difficult to locate items. Each '''room''' in a house is used to for a<br>'''specific purpose''' to be more productive to perform a task such as a kitchen, bedroom, bathroom, etc.
You will be creating the following '''directory structure''' within your home directory<br>(refer to diagram on the right side).
'''Perform the Following Steps:'''
'''Perform NOTE:''' For several of the following commands, you will be using '''<u>your</u> Seneca username''' to replace the Following Stepstext:"'''your-seneca-id'''" in a pathname.
# '''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 the following Linux command: <span style="color:blue;font-weight:bold;font-family:courier;">ls /home/your-seneca-id/uli101xx</span><br><br>There are no contents that are contained in this newly-created directory; therefore, no contents appear. A useful option '''-d''' can be used to confirm that the actual <u>directory</u> has been created as opposed to viewing the contents of the directory.<br><br>
