If you using console a lot and don’t use any “fancy” desktop manager (I mostly use Ratpoison) and you need quick reminder, here is simple solution using
$ sleep 180 && mplayer musicfile.mp3
…and it will start playing music after 180 seconds or you can pop up picture with:
$ sleep 180 && sxiv picture.jpg
…or in my case:
$ sleep 600 $$ ~./alarm.sh
…and it pops up Ratinfo. Here is my example of alarm.sh:
DATE=$(echo -n $(date +%B,%d %H:%M:%S )) INFO=$(echo -n "Coffee is ready!!!!! Date: $DATE") ratpoison -c "echo $INFO"
…and it display “Coffee is ready!!!!!” with date and time beneath.
