Non-zero exit code when updates are available

Hi, I did three sessions with the routeros-upgrader tool:

If the tool returned a non-zero exit code when updates were available, it could be used to monitor/automate mass upgrade.
However, it would be worth taking care of standard input processing ;) and perhaps introducing the -n (force no) option.

Hi @issrec

many thanks for your interest in this project!
Please check out this prerelease

I've added a -n flag and added the exit-code 2 when:

• Updates are pending and no is set via "N" in the first interactive prompt
• Updates are pending and no is forced via -n

Does this solve your use case?

Hi @Marco98,
this is a great change and it works:

A small digression.
My routers are set to knock. When they are not reachable, the error code returned is 0 - which suggests that everything is OK and there are no pending updates, which is not true 😉:

$ ./routeros-upgrader -n; echo $?
2024/07/26 11:34:54 checking installed packages

Hi @issrec,
yeah it makes more sense in this case with a non-zero exit code.
I've now added an error to this. Please see this prerelease

Hi @Marco98,
I thank you for the change. It looks better:

$ ./routeros-upgrader -n; echo $?

|DN> MikroTik2: unreachable
2024/07/29 07:37:47 no action required - exiting

@issrec thank you!
Do you need additional tweaks for your automation or can i release the changes?

[issrec]

Overall it's OK and that's enough for my automation.
For now I see one/two situations that are not recognizable:
