Remind

To show today's reminders:

/usr/local/bin/remind ~/.reminders

To show your weekly calendar:

/usr/local/bin/remind -c+ ~/.reminders

And if you used my Remind_Scripts#Convert_Remind_to_iCal tip on using IF statements to avoid duplicate events when syncing back and forth with iCal, use the following commands:

Daily:

/usr/local/bin/remind -irem2ics=1 ~/.reminders

Weekly:

/usr/local/bin/remind -irem2ics=1 -c+ ~/.reminders

-irem2ics=1 is derived from the IF statement: IF defined("rem2ics")
