      I am breaking this down very slowly for myself. Not a bash master by any measure, but I do want to continue learning it. Arrays seems somewhat annoying in Bash. I will likely learn python to deal with more complex stuff I may need to do with them.

      This would likely be easier in Python and more straightforward.

      Yep

        I was going to suggest that. This would likely be easier in Python and more straightforward. If you have to stick to bash, don't declare your arrays in a looplike that, just declare them in the variables at the top

        Alright I did that. Is there something better than ShellCheck for bash syntax checking that you know of? Do you just use bash -n script

        I don't know of anything better.

          Here's a quick setup in Python if you want to try it instead.

          import os
          import gnupg
          
          
          encrypted_dir = "/tmp/encrypted_files"
          archive = "/tmp/archive"
          password = os.getenv(os.getenv("DECRYPT_PASSWORD"))
          gpg = gnupg.GPG(gnupghome='/home/user/.gnupg')
          responses = {}
          
          
          def decrypt_file(file: str, password: str):
              out_name = f'{encrypted_dir}/{file}.decrypted'
              stream = open(f'{encrypted_dir}/{file}', "rb")
              return gpg.decrypt_file(stream, passphrase=password, output=out_name)
          
          
          
          for file in os.listdir(encrypted_dir):
              if file.endswith(".gpg"):
                  stat = decrypt_file(file, password)
                  responses[file] = stat
              else:
                  continue
          
          
          for file in responses:
              status = responses[file]
              if status.ok:
                  os.rename(f'{encrypted_dir}/{file}', f'{archive}/{file}')
                  print(f'File {file} decrypted and moved')
              else:
                  print(f'File {file} had error, {status.stderr}')

            @stacksofplates Thanks. That will help as a reference for later but I did want to figure out how to do this in bash as well. It's just kind of a challenge I don't want to give up on yet.

              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.

                  No prob. I'm not a bash expert (and I find it annoying lol) so once things get past a certain point I give up with it.

                      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.

                            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.

                              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:

                                    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 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.

                                      technically there is no other viable option because I don't have the time to learn the alternative before I need this to be done by. the plan is to remake it in python later. after I convert some stuff and feel comfortable, I'll only use python

                                      I learned the basics of python in a day or two. I bought udemy course and built a few python apps. I was able to find tutorials to build security tools like scrapers and scanners.

                                      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.

                                          the plan is to remake it in python later. after I convert some stuff and feel comfortable, I'll only use python

                                          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.

                                          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.
