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:ssA': ex. 1:30:00PM, 1:30:00pm
'h:mmA': ex. 1:30PM, 1:30pm
'hA': ex. 1PM or 1pm
'HH:mm:ss': ex. 13:00:00
'HH:mm': ex. 13:00

The following are also supported, but they must be quoted:

‘h:mm:ss A’: ex. “1:30:00 PM”, ‘1:30:00 pm’ ‘h:mm A’: ex. ‘1:30 PM’, “1:30 pm”

Be aware that remind runs in the background until the appointed time, issues the notification, and only then terminates. If the process is killed or some how lost, perhaps by restarting the computer, the reminder is also lost. However, you can put the computer to sleep. When the computer wakes, you will either receive a past due notification with an indication that it is being given late, or the process resumes waiting for the appointed time.

When run, remind prints the process ID (PID) of the reminder process that was forked into the background. You can run the kill program with this PID to delete the reminder.

You can use pip to install the program:

pip3 install --user schedule-reminder

It installs into ~/.local/bin, so you will need to add that to your shell’s path. You also need an active notification daemon. To check whether you have one, run notify-send testing. If you get ‘command not found’ you will need to install one. I can recommend dunst.
