Allow nohup background running
Hello there,
Currently, on Linux, if you try to run ODD in an unattended way, for instance with nohup, it does not work at all, the following message is returned:
Console input is redirect, maybe it is run inside another host. This could mean that no input will be send/processed.

Could you allow such capacity ?

Hi,
I have never heard of this. How do you start/use it? What is the purpose?
You use it like this nohup <command> & in order to have the command being run without any shell attached.
https://www.digitalocean.com/community/tutorials/nohup-command-in-linux
It is usually used for long-running tasks.
I've tried reproducing it, but I can't :)

Watch out:
- I am using the selfcontained version above.
- try to press "Enter" when you see
nohup: ignoring input and appending output to 'nohup.out'as the coredump does not come without interaction.
And by the way, I also just reproduced it with the current latest https://github.com/KoalaBear84/OpenDirectoryDownloader/releases/download/v3.4.0.2/OpenDirectoryDownloader-3.4.0.2-linux-x64-self-contained.zip
Cheers!
