Programmatically schedule script execution with launchd or crontab

I know how to create a configuration to schedule eg. a daily execution of a script with launchd or crontab on MacOS. However, I run into a scenario where I need to schedule the one-time execution of a script as part of a(nother) ruby script.



The hacky solution to that would be to manually write a plist file, and then running launchctl load, however that requires sudo privileges.



Is there a better way of programmatically scheduling the one-time execution of a script in MacOS?






bash macos command-line cron launchd

  • If your script is web-based, you could use a 3rd-party service, such as crono, to programmatically set up your jobs.

I would use the at command. I haven't used it on mac os, but I would bet you can do brew install at then you can run the at command to schedule a job at a specific time. 



echo script.sh | at tomorrow noon
