Matrix and Linux Commands
- Matrix is a cluster of computers running CentOS (a version of Linux) at Seneca's Newnham campus.
- To access Matrix, you must be on campus, in a lab, or connected to SenecaNet, or off campus with a VPN connection.
- Web access is allowed, but not command-line login.
- SSH (Secure Shell) is used to connect to Matrix from any Seneca lab workstation or personal computer.
- SSH provides secure, encrypted communications over a network connection.
Connecting to Matrix
- Use the command
ssh [email protected]to connect to Matrix. - Replace
senecausernamewith your actual username. - You will be prompted to confirm the "fingerprint" of Matrix and enter your Seneca password.
- If you encounter an error message, check the error message and try again.
- Remember to log out using the
exitorlogoutcommands or Ctrl-D when finished.
Using PuTTY to Connect to Matrix
- Download and install PuTTY for Windows.
- Run PuTTY with the settings: Host Name:
matrix.senecapolytechnic.ca, Port:22, Connection Type:SSH. - A terminal window will pop up, asking for your username and password.
Connecting to Matrix from MacOS/Linux

Hierarchical File Systems
- A file system is a method of organizing and retrieving files efficiently from a storage medium.
- Both Linux and Windows use hierarchical file systems.
- Files are organized in folders and subfolders.
- In Windows, the hierarchy starts from drives (e.g., C:, D:).
- In Linux, the topmost directory is the root (/) and all files and directories appear under root.

exitorlogoutcommands or Ctrl-D when finished on Matrix. - Use the
man asciicommand to see the ASCII table. - You can set your prompt to (almost) anything you want in both Windows and Linux.
