___ ___ erkimt .sh Script to run a program in python inside Cron ______ qstntxt ___

Good morning. I'm having a problem with a python program that I did. What happens is that when I run my program through the command line with this command it works normal:

%pre%

So I did the following program in .sh

%pre%

When I run through it the program also works but when I include this command in crontab this way:

%pre%

My program starts execution, it goes into memory and it works for a few seconds and simply stops without error or without leaving the memory.

Could anyone help me generate a file that controls the execution of my program in python if mine is wrong? or would you have any tips on how to make it work?

%pre%

That in turn would create the lock %code% file to control the single instance of the process.

What would allow such a configuration in its %code% :

%pre%
