Return Values in Bash Script and generate e-mail which shows successes, errors and if the directory is empty

wirestyle22

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 seem somewhat annoying in Bash. I will likely learn python to deal with more complex stuff I may need to do with them.

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

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.

stacksofplates

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.

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 since added to these scripts and combined some of them. I'm not a python master, but it's very easy to pick up. There's also so many resources out there.

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:
#!/usr/bin/env bash
source "/home/user1/subdirectory1/master.sh"
decryptedFolderPath="/home/user2/subdirectory2/"
archiveFolderPath="/home/user1/subdirectory1/archive/in/"
extension=${fileName##*\.}
newFileName=${fileName%.*}
fileWithoutTimestamp="$newFileName.$extension"
encryptedItems=$(ls encryptedFolderPath*.pgp)
statusArray=()                                   

for i in $encryptedItems
do
gpg --batch --homedir /home/user1/.gnupg/ --passphrase "$PASS" --list-only --list-packets --yes --decrypt "$i" | grep -q "encrypted" > "$decryptedFolderPath"/"$fileWithoutTimestamp"
outPut=$(gpg --batch --homedir /home/user1/.gnupg/ --passphrase "$PASS" --list-only --list-packets --yes "$i" | grep -q "encrypted")

if [ $? != 0 ]; then
echo "$i is not a pgp file"
statusArray+=("failed to decrypt $i, with status code $? output from pgp: $outPut")
fi

if [ $? == 0 ]; then
statusArray+=("Succesfully Decrypted $i")
echo ${#statusArray[@]} | mail -s 'report' [email protected]

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.
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 since added to these scripts and combined some of them. I'm not a python master, but it's very easy to pick up. There's also so many resources out there.

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