    50 10  * * py script
    50 11  * * py script
    ...
    50 23  * * py script

its posible, only 1 line command?

Answer 1

If you want to run crom job at every 50 minute from 09:50 to 23:50, try this:

*/50 9-23 * * * /path/to/py /path/to/script

It will be executed "At every 50th minute past every hour from 9 through 23."

If you want to the cron job to be executed as a specific user, try this:

*/50 9-23 * * * username /path/to/py /path/to/script

This second version only works for /etc/crontab and cron files located in /etc/cron.d/.

Other possible combinations you can try at crontab guru
