For some reason, most macOS users avoid the terminal. Some of them don’t even know a shell even exists.
I’m not going into why you’d better off using the terminal, at least for the most common tasks. But I am going to show you some cool and fun cli apps that you can install and use right now. Maybe this will spark your interest.
Jump over the break to check out the apps, in no particular order…

“The Matrix” screensaver in your Terminal. UniMatrix is based on CMatrix, and if you ask me it’s better than CMatrix. However it’s also a tiny bit more complicated to install and run. It’s just a couple of extra steps, no big deal.

brew install cmatrix
HOW TO RUN CMatrix
1. Simply type
-a: Asynchronous scroll, more like the movie/original screensaver -b: Partial bold text mode -B: All bold text mode -f: Force the linux $TERM type to on -l: Linux support for linux console matrix.fnt font -n: No bold text mode -o: Use "old-style" scrolling - less like the movie, more like the Win/Mac screensaver. -s: "Screen saver" mode. Any key aborts (default is "eye candy" mode, must abort with control C) -x: X window mode, use if your xterm is using mtx.pcf -u [update]: Update delay (0-9, default 4). -C [color]: Use color for matrix (default green)
CMatrix keystrokes available while running (not available in -s mode):
a: Toggle asynch mode b: Enable partial bold text B: Enable all bold text n: Disable bold text 0-9: Change update delay ! @ # $ % ^ & ): Change the color of the matrix to the corresponding color: ! - red @ - green # - yellow $ - blue % - magenta ^ - cyan & - white ) - black

Add the follwoing line:

This way all you have to do is open up Terminal and type
NOTE: .bashrc or .zshrc are hidden files in /Users/your-username/. Check the link above to learn how to toggle on/off the display of hidden files on macOS.
