What's good fam? Have you ever tried to debug your bash script and just couldn't figure out what's going on? Well, look no further cause we got you covered! Check out this dope tutorial on how to debug a bash script like a pro.

First off, let's make sure we all on the same page here. A bash script is a script written for the Unix shell, which is a command-line interface. If you not sure what that means, don't worry about it. Just know that if you wanting to automate some tasks on your computer, bash scripts are the way to go.

So, let's dive in. The first step to debugging a bash script is to make sure you running it in debug mode. How do you do that? Easy fam, just add -x to the shebang line at the top of your script. It should look something like this:

 #!/bin/bash -x

Once you done that, run your script as usual and watch the magic happen. You should see every command that being executed in your script with a + in front of it. This is particularly helpful when you have a large script and getting lost in the maze of commands. By having the debug information, you can see exactly where things are going wrong.

Another helpful tip when debugging bash scripts is to echo your variables. This may seem redundant, but it can save you some serious headaches. For example, if you have a variable called $filename that not being set correctly, you can add this line before executing the command using that variable: 

echo "The filename is $filename"

By doing that, you will be able to see the value of that variable and make sure it is what you expecting it to be. Trust us, this can save you hours of frustration.

Lastly, if you still struggling to debug your bash script, don't be too proud to ask for help. Head on over to the Unix & Linux Stack Exchange and ask your question. There are a ton of helpful and knowledgeable folks over there that would be happy to assist you.
