How to open a file and shut down your computer with crontab?
Follow my attempt:
30 07 * * * killall qbittorrent (funcionando)
50 07 * * * shutdown -r 1 "Desligando desktop" (não funciona)
30 12 * * * qbittorrent & (não funciona)
55 13 * * * killall qbittorrent (funcioando)
08 20 * * * qbittorrent & (não funciona)

The following commands worked for me (I used firefox in place of qbittorrent because I don’t have qbittorrent installed):
$ sudo su
to log in as root and nay change the global crontab table (located in /etc/crontab).
$ crontab -e
to change the root user crontab, with the following entries:
29 * * * * killall firefox
30 * * * * sudo shutdown -r now
35 * * * * su USUARIO -c "DISPLAY=:0.0 firefox"
36 * * * * killall firefox
37 * * * * su USUARIO -c "DISPLAY=:0.0 firefox"
Where USUARIO can be any user of your system with which you wanted to run the command.
I believe your command just wasn’t working because $DISPLAY was not defined, and the program cron doesn’t understand anything about displaying things on the screen.
That’s right, thank you.
