What are some advanced shell scripting techniques I should know?

Some advanced techniques include using functions, error handling, and leveraging command-line arguments.

Can you explain how to use functions in shell scripts?

Sure! Functions allow you to group commands and reuse them. You define a function using the syntax: function_name() { commands; }.

What about error handling? How can I implement that?

You can use set -e to exit on errors, or check the exit status of commands using $? to handle errors gracefully.

Are there any best practices for writing shell scripts?

Yes, always comment your code, use meaningful variable names, and test your scripts in a safe environment before deploying.
