What does the 'echo' command do?

The echo command in Bash is used to display a line of text or a variable value to the standard output (usually the terminal). It can also be used to create output in scripts or command-line operations.

Here are some common usages:

1. Basic Usage:

   echo "Hello, World!"

2. Displaying Variables:

   name="Labby"
   echo "My name is $name"

3. Using Options:

   • -n: Do not output the trailing newline.
   • -e: Enable interpretation of backslash escapes.

   Example with options:

   echo -e "Line 1\nLine 2"

This command is widely used for debugging and displaying messages in scripts.
