ubuntu cmatrix怎么使用

Installing cmatrix on Ubuntu
To use cmatrix on Ubuntu, you first need to install it. The easiest way is via the apt package manager. Open a terminal and run:

sudo apt update && sudo apt install cmatrix

Enter your password when prompted. This installs the latest version of cmatrix available in Ubuntu’s repositories.

Basic Usage: Launching the Matrix Effect
Once installed, start cmatrix by simply typing:

cmatrix

Press Enter, and you’ll see a dynamic green matrix animation filling your terminal—just like in The Matrix. The default color is green, and the text scrolls vertically to mimic the movie’s iconic visual.

Customizing Colors
You can change the matrix color using the --colors parameter. For example:

• cmatrix --colors=2 switches to blue,
• cmatrix --colors=3 enables red,
• cmatrix --colors=4 uses yellow.
  For a rainbow effect, try cmatrix --colors=all. You can also edit the ~/.cmatrixrc file (create it if it doesn’t exist) to set a permanent color scheme. Add lines like color=green or color=blue to customize further.

Adjusting Display Options

• Add Borders: Use --border to frame the matrix with a border.
• Set a Title: Add a title with --title="Your Text" (e.g., cmatrix --title="My Matrix").
• Disable Real-Time Updates: Use --no-refresh to freeze the animation (useful for taking screenshots).
• Output to a File: Redirect the output to a text file using cmatrix > matrix_output.txt.

Keyboard Shortcuts
While cmatrix runs, use these keys to control it:

• q: Quit the program gracefully.
• Ctrl+C: Force-stop cmatrix (use if quitting doesn’t work).
• Arrow Keys: Navigate process lists (if monitoring system resources).

Monitoring System Resources (Advanced)
cmatrix can display real-time system stats alongside the matrix. Use these command-line options to enable specific metrics:

• -u: Show CPU usage percentage.
• -m: Display memory usage details.
• -r: Show swap partition usage.
• -q: Display disk space usage.
• -C: Show the number of running processes.
• -N: Display network interface information.
  Combine options for a comprehensive view. For example:

cmatrix -u -m -r -q

This shows CPU, memory, swap, and disk usage in the matrix.

Exiting cmatrix
To stop cmatrix, press q or Ctrl+C in the terminal. This returns you to the command prompt.
