[MM3-users] Running mailman shell commands in a script

Hello, I understand that the mailman shell is basically interactive. I need to run some actions as adding and deleting users in a Linux shell script, or even from another python program. How does that work?

In fact, I miss the commands that were in the bin directory of the old mailman2 installation. Wouldn't it be nice to add them again to mailman3?

Cheers, Eggert
