The at command does exactly what you want. Record a sound file of your medicine alarm and... $ sudo apt install at $ at 0240 warning: commands will be executed using /bin/sh at> aplay /home/sam/medicine.wav at> ^D job 1 at Wed Mar 22 02:40:00 2022 Enter commands to be run at the particular time, and finish with a control-D (end of file). at will acknowledge with the job number and the time it will be run. Feel free to test with 'at now +2m' You can use atq to show you the queue of at jobs, and atrm to remove one. Now, if the alarm happens more often than that on a regular basis, you could use cron instead. cron is a little more complicated, but can handle things like "every Tuesday, on hours divisible by 4". -dsr-
