BatControls (OS X) for Mac

From LAJ Design:

BatControls lets you schedule events (reminder messages, shell commands, and launch files) to execute when you want. Ever have a project where you had to copy or move a file every two hours, after about 4 hours you get tired of copying or moving. Let the computer do the work with BatControls. Customizable for unlimited simultaneous timers to run. It has three modes: reminder message, shell, and Launch Only. In reminder message mode, set the time and date and a reminder window will popup at that time and date. In shell mode all commands are run like you are in command or in terminal. The results from the execution are copied into the log. In Launch Only mode, the user specifies a files and BatControls will launch the file as if it had been opened in explorer.
