Study Notes

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 senecausername with 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 exit or logout commands 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

Simple Linux Commands

  • echo: prints something on the screen.
  • cal: displays the calendar.
  • date: shows the date and time.
  • who: prints information about the currently logged-in user(s).
  • whoami: prints the name of the current user.
  • cls or clear: clears the terminal screen and shows the prompt in the first line.
  • tree: shows the folder (and file) hierarchy in a tree format.
  • dir or ls: lists information about files and folders.

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.

Important Notes

  • Always log out using the exit or logout commands or Ctrl-D when finished on Matrix.
  • Use the man ascii command to see the ASCII table.
  • You can set your prompt to (almost) anything you want in both Windows and Linux.
