Remind - Schedule Notification Reminders¶
Remind schedules notification reminders. You can specify the time either using a specific time, such as 3:30pm, or you can specify it by the time from now in minutes or hours, or you can use both. So, you can say:
remind 4pm remind 4pm -15m remind 10m
In the first case the reminder goes off at 4pm, in the second it goes off at 3:45pm, and in the third it goes off in 10 minutes. When the time expires a notification is raised. You can specify the message in the notification using the -m or –msg option. Or you can add the message after specifying the time. Any argument that cannot be processed as a time switches the argument processing from time to message, and all subsequent arguments are taken to be part of the message:
remind 1h meet Maria
You can specify the time from now using seconds, minutes, hours, etc. For example:
remind 3h 15m
You can use noon and midnight as aliases for 12PM and 12AM.
When specifying the time of day, you can use the following formats:
'h:mm:ss A': ex. 1:30:00 PM, 1:30:00 pm 'h:mm:ssA': ex. 1:30:00PM, 1:30:00pm 'h:mm A': ex. 1:30 PM, 1:30 pm 'h:mmA': ex. 1:30PM, 1:30pm 'hA': ex. 1PM or 1pm 'HH:mm:ss': ex. 13:00:00 'HH:mm': ex. 13:00
Be aware that remind calculates how long it must wait and then sleeps in the background before waking up and delivering the message after the prescribed amount of time has passed. If you turn you computer off during this time the sleeping process will be killed and no reminder will be given, even if you turn your computer back on before the scheduled time. If you put your computer to sleep, the sleeping remind process will not recognize the passage of time and so the reminder will be given late, delayed by the length of time your computer was asleep.
You can use pip to install the program:
pip3 install --user schedule-reminder
