CRON Job that changes a txt file

My name is Colin.

I want my Linux server to edit a file at 0am. It should change some values in a txt file (Randomized). I heard about CRON Jobs but I don't know how to use them. I hope somone can help me with my problem :)

Thank you for your answers.

Solution

  • You can add a new crontab with: crontab -e. Please notice that this crontab runs with the privileges of the user that inserted it.

    If you want to run a program always at midnight you can use this line:

    0 0 * * * <COMMAND TO EXECUTE> > <PATH TO FILE TO WRITE OUTPUT AND ERRORS> 2>&1
