#CLI shortcut keystrokes(linux&MAC)
Ctrl+L: Clear the screen. This is similar to running the “clear” command.
Ctrl+C: Interrupt (kill) the current foreground process running in in the terminal. This sends the SIGINT signal to the process
Ctrl+Z: Suspend the current foreground process running in bash. This sends the SIGTSTP signal to the process. To return the process to the foreground later, use the fg process_name command.
Ctrl+D: Close the bash shell.This is similar to running the exit command
Ctrl+L: Clear the screen. This is similar to running the “clear” command.

Ctrl+S: Stop all output to the screen. This is particularly useful when running commands with a lot of long, verbose output, but you don’t want to stop the command itself with Ctrl+C.
Ctrl+Q: Resume output to the screen after stopping it with Ctrl+S.
