Clearing the screen

The tput clear terminal command can be used to clear the current command-line session. You could type tput clear all the time, but wouldn't just cls be nicer?

Here's a simple script that clears the current screen:

Chapter 4 - Script 1

#!/bin/sh
#
# 5/8/2017
#
tput clear

Notice that this was so simple I didn't even bother to include a Usage message or return code. Remember, to make this a command on your system do this:

• cd $HOME/bin
• create/edit a file named cls
• copy and paste the preceding code into this file
• save the file
• run chmod 755 cls

You can now type cls from any terminal (under that user) and your screen will clear. Try it.
