When should you use variables in bash?

Variables in Bash are essential for managing and manipulating data within your scripts. You should use variables in the following scenarios:

• Storing Values: When you want to store a value that you can use later in your script.
• Reusability: To avoid repetition; instead of typing the same value multiple times, store it in a variable.
• Parameterization: When writing functions or scripts that require different inputs, variables can be used to accept parameters.
• Improving Readability: Using descriptive variable names can make your code easier to understand.
