Automate Add new users to Server at specific time of the day

[siclib]

I am not sure if this is the place for this topic but I think ill post it here anyway.

As far as I know, calibre-server has to be turned off in order to manage users.
I am using ubuntu and ideally I want to put soon-added members at the end of the day because I dont want to stop the server at middle of the day and cant stay awake midnight also. Is it possible to achieve this with bash script?

Example:
1AM
check if users.txt is empty or not, if not
stop calibre-server
do a while loop to grab users and passwords from users.txt and add to userdb
delete users and passwords
start calibre-server

Thank you very much

You should write a python script for that, not bash, it will be easier. Something like:

import subprocess

users = tuple(filter(None, open('users.txt').read().splitlines()))
if users:
    subprocess.check_call('systemctl stop calibre-server'.split())
    for user in users:
         username, password = user.split()
         subprocess.check_call(['calibre-server', '--manage-users', '--', 'add', username, password])
    subprocess.check_call('systemctl start calibre-server')

This is exactly what I am up to, python surely makes things much easier
In your code i can see you use "-- add" with a space. Is there any documentation on how to edit library restrictions and prompt read-only access? I want to suppress the dialog and input it thru one or a series of commands like what you did there.
Thank you in advance

No, I'm afraid there is no command for automatically editing restrictions/readonly. You could probably script something up using expect or pexpect. Or open a ticket asking for the feature.
