How to run commands from a file in a screen window via cron?

Question

linux

Hello!
Such a task:
(Ubuntu server 18.04)

A console program runs in the screen terminal that executes commands (if you enter them manually and press enter)

There is a file where commands are written, for example

print('Hello')
print('World')

How via cron execute the commands that are in the file in the screen window?

Answer 1

Let's say you have a screen called "myprogramscreen"
send the command "mycommand" there and press enter like this:
screen -p 0 -S myprogramscreen -X eval 'stuff "mycommand"\015' then
make a bash script that will do this and adding it to cron is not difficult.
