Variables: The Unsung Heroes of Shell Scripting
What's the point of shell variables, you ask?

Variables are the backbone of shell scripting. They help you store values for later use.

Here's an example of a variable in action:

MY_VAR="Hello, World!"

Now, you can use this variable like so:

echo $MY_VAR
But wait, there's more! You can also use variables with loops!

Loops are the key to automating tasks and reducing repetition.

Here's an example:

for i in {1..10}; do echo "Hello, World!"; done
