What is the purpose of the -e option?

The -e option in the echo command enables the interpretation of backslash escapes. This means that special characters, such as newline (\n), tab (\t), and others, can be used in the output string.

Example:

echo -e "Hello,\nWorld!"

Output:

Hello,
World!

In this example, the -e option allows the \n escape sequence to create a new line between "Hello," and "World!". Without the -e option, the output would display the escape sequence literally:

echo "Hello,\nWorld!"

Output:

Hello,\nWorld!

Summary:

The -e option is useful for formatting output with special characters in shell scripts or command-line operations.
