Rather than mess with multiple arrays, you can just have a single dictionary that holds the file and status. A single function can decrypt the file. Then just save the file name and status of the decryption in that dictionary. Then loop through the dictionary and here I just print the data, but you could email it or send to Slack or whatever.

This was a quick pass so probably can be cleaned up a bit.

My reasoning behind two arrays was to keep it organized. If I do all successes in one and then all failures in the other. So I have this now:

I think this is what you meant, right?
Well no. I meant Python can easily work with dictionaries (hash maps) vs doing multiple arrays. You'd have to switch to a hash map in Bash vs the multiple arrays.
Gotcha. Yeah it sounds more convenient it just going to take me more time to learn than I have with this current script
Isn't this the one you've been working on for like a year now? I'd say that's enough time to learn a little about scripting.

I built the original one awhile ago. Now I want to build more functionality into it. It's been static for a very long time.

Except, bash is not the place to build more functionality.

You use bash for basic stuff, or when there is no better option available.

I've used python for interfacing with sensors connected to a rPi. It's easier to picup than BASH imo.

I personally hate python because of the space indentation defining code blocks. even if I always space indent my code.

But the language is simple and straightforward.

But the language is simple and straightforward.

I always hated it for that, but PyCharm and other IDEs make it pretty easy. PyCharm is probably the best. I'm a fan of the JetBrains tools.

On the Python note, I wrote a microservice for a PoC we are doing. I wrote it in Go and it takes a JWT and some information about a secret stored in Vault and authenticates to Vault with the JWT and retrieves the secret. It was around 500-600 lines of code. I rewrote it in Python today and it was less than 40 lines of code.

While a good thing, if you have a working bash script just Google each line “in python”

Declare array in python
