Here are some commonly used escape sequences you can use with the -e option:

• \n - Newline: Moves the output to the next line.
• \t - Tab: Inserts a horizontal tab space.
• \\ - Backslash: Outputs a single backslash.
• \" - Double Quote: Outputs a double quote character.

Example Usage

Here’s how you can use the -e option with echo:

echo -e "Hello,\nWelcome to LabEx!\n\tEnjoy your learning."

Output:

Hello,
Welcome to LabEx!
    Enjoy your learning.

In this example:

• \n creates new lines between "Hello," and "Welcome to LabEx!" as well as before "Enjoy your learning."
• \t adds a tab space before "Enjoy your learning."
