Acabei de fazer o seguinte script para essa finalidade. Eu chamei de timelimit
:
#!/bin/bash
#timelimit - Set daily time limits for specific applications

notify-send -i $app_name "Time left to play with $app_name for today: $time_to_play_left"

fi
countdown $time_to_play_left
pid=$(pgrep -x $app_name)
if [ "$pid" != "" ]; then kill $pid; fi
fi
done
Não se esqueça de torná-lo executável:
chmod +x timelimit
Sintaxe:
timelimit APP_NAME
Importante:
- Você pode testar esse script no terminal, mas deve ser executado na inicialização do sistema. Para fazê-lo funcionar na inicialização, consulte Como executar scripts no arranque?
-
Esse script deve ser reiniciado à meia-noite se você não desligar o computador à noite. Para fazer isso, você pode adicionar um cron job como:
00 00 * * * kill 'pgrep -x timelimit' && timelimit APP_NAME
