The history command keeps track of each command you enter in the terminal.
Also when you use the up arrow key, it will give you the previous commands you entered.
To enter a command without having it recorded in history or being able to retrieve it using the up arrow key, add a space in front of your command like so:
echo "This command will be remembered"
echo "This one won't"
echo "This last one will be remembered"
