Bash exit codes & command chaining | #1 Practical Bash

Ever wondered what exit code 0 or exit code 255 means in the terminal? This first video of the brand new "Practical Bash Scripting" series will teach you all you need to know about exit codes. Having understood bash exit codes you can make use of command chaining using the && and || operator. And - as with every Practical Bash video - I'll show you a real-life example of where this comes in handy!

The most underrated YT channel. You are doing a great job, Sir. Thank you so much.

[@kubucation]

Thanks a lot. The Channel is still tiny, yes ... but it’s also growing. Interesting times ahead.

love it ! very clear YT, I was led from your "how Https work? ", the best ssl/https YT so far? thanks a lot ! keep going !

[@thomasloven]

For the off chance that anyone reads the comments; the reason 0 means success and anything else means failure is because generally things can work in One Way, but not work in Infinitely Many Ways - and it may be interesting to know which one it is this time.

[@kubucation]

Great comment. I read it, I’m sure others will too :-)

[@anushams4196]

Thanks ❤️

[@NavyaTeja7]

You just "KISS"ed (Kept It Short and Sweet) it.....😉

[@kubucation]

Thanks! This series will have plenty of short videos, usually between 5 and 8 minutes that focus on bash or terminal related topics. In the beginning there are some essentials of course, but who knows where the journey will lead us to. So far I have planned the first 5 videos, but I don't think there's an upper limit to this series.

[@KrishnaDasPC]

Is bash development dead?

[@kubucation]

How do you mean that? Why would it be dead?

[@KrishnaDasPC]

@@kubucation I mean the development of bash. New features. Like php 5 to 7 now. I use bash for backup scripts but couldn't find inbuilt support for associative arrays json and many other modern features.

[@johnny-mnemonic13]

this video sucked,, didn't get into using exit codes in depth. Started off right but then veered into operators. Fail.

[@kubucation]

Thanks for your feedback. Feel free to list exit-code related topics you were missing. I can always add an additional more in-depth video later on.

[@johnny-mnemonic13]

@@kubucation well what I was really confused is why use exit codes within bash script. Then when and where to use them within the script as well. I did some more searching and I think I got it, so I'm good with that. Now I just learned that the RHCSA exam got updated to include containers? I'm like geezer, there's hardly any good material covering these so I'm f'd if I don't find something soon as I am like 80% ready for the exam. If you can cover this to the exam requirements you got yourself a subscriber and likes.
