Here is the video version, if you prefer it:
Fixing errors, also known as troubleshooting, is a process or removing errors from your bash script.
If you adhere to the rule which I laid out before, which was “Use single quotes to enclose values unless you have a concrete reason not to”, you will be fine most of the time. For the times when you are not fine, literally copy and paste the error message you’re getting into Google and you will get some suggestions.
There is a finely written piece on this in (Shotts, 2019), which again, let me remind you, is free on the World Wide Web, so go read it.
Thank you for reading!
