The command "picom &" is used to start the picom compositor in the background.

Here's a breakdown of the command:

• "picom" is the actual command that starts the picom compositor. Picom is a lightweight compositing manager for X11 desktop environments, primarily used for adding visual effects like transparency, fading, and shadows to windows and menus.

• "&" is a special character in the command-line interface that tells the shell to execute the command in the background. This means that the picom compositor will not hold the terminal open, allowing you to continue using the terminal for other commands.

By using "picom &" command, you initiate the picom compositor and allow it to run independently in the background, while still having access to the terminal for other tasks.
