related to #357

Just a suggestion, sed will do all the work in a single line. Try this out:

Remove lines 9-13(the sed_string function), remove 31 and replace line 32 from
sed -i "s/${SED_STRING}" $DATABASE
to
sed -i.bak "s%^$USER.*%$ENTRY%g" $DATABASE

That should search the database for $user and replace the line with the new $ENTRY. I added the .bak in case the user made a mistake and needed to rollback the change.

The only issue I could think of is if % was in the encryption. As far as I've been able to tell and test, I have not come across it so I don't believe would be.

Also should update setup.sh to include the usage for:
$0 email update <email> <password>

and add the case:

update)
    shift
    _docker_image editmailuser $@
    ;;

Let me know if I can make a pull request for anything to help.

@marceloschmidt Thank you for submitting your script! Can you please write a test. Writing tests with bats is so nice.

I'll have to learn some bash programming 😂 but give me a few days and I'll add some tests! Thanks!

Yeah, no problem @marceloschmidt

Hi @marceloschmidt, did you get a chance to look at batsintegration test?
We can help you if necessary. Feel free to ask. Tests are important to make this robust to changes.
