___ ___ 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?

Since you are apparently in %code% , you could dispense with your %code% , passing the responsibility of checking if another process is already running for your %code% code, see:

%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%

I solved the problem as my final cod was

Since you are apparently in Linux , you could dispense with your .sh , passing the responsibility of checking if another process is already running for your Python code, see:

import fcntl, sys

pid_file = '/var/run/script.py.pid'

fp = open( pid_file, 'w' )

try:
    fcntl.lockf( fp, fcntl.LOCK_EX | fcntl.LOCK_NB )
    print('Em execucao!')
except IOError:
    print('Jah estou em execucao!')
    sys.exit(1)

# ....

print('Finalizado!')

sys.exit(0)

That in turn would create the lock /var/run/script.py.pid file to control the single instance of the process.

What would allow such a configuration in its crontab :

* * * * * root /usr/bin/python3 /home/linaro/programa/main.py > /home/linaro/log.txt
