The echo and printf commands are used to print text. In this example, the echo command is used to print Hello World.

echo "Hello World"

Escape back slashes

By default, the echo command will print back slashes.

~]# echo "Hello\tWorld"
Hello\tWorld

The -e option can be used to escape back slashes. In this example, by escaping back slash, \t is properly interpreted as a tab.

~]# echo -e "Hello\tWorld"
Hello    World

In this example, \n is properly interpreted as a new line.

~]# echo -e "Hello\nWorld"
Hello
World

Do not print new line

The -n option can be used to not print a new line at the end of the output.

~]# echo -n "Hello World"
