Is there any easy way to schedule repeated jobs in Mac OS X? I know I could use cron, but I'm looking for a more user friendly way to do it, a GUI for schedules, something like this.
You can schedule jobs via iCal. Create an event. Edit the event, and you'll see "Run Script" and "Open File" as options as alarms.
Lingon is a GUI for creating and working with launchd. It's no longer being worked on, but works well for creating and editing Launch Agents and if you are on Leopard or Snow Leopard it's the suggested method over cron.
This solution does use crontab but makes it user-friendly by using the Automator
Adding a calendar event tends to clog up iCal for me. I'm using a combination of Automator and crontab.
On the Automator part, I'm recording each action I need to perform as an app (Automator > File > New > Application Template) and save it to a convenient location (File > Save as). Make sure you save it as an Application and not Workflow.
Then it's just a case of adding a cronjob for it:
0 * * * * open /path/to/the/save/automator/app
Friendly would be nice, but right now I'm just looking for something that will run an application at a specified time on specified days -- or even every day -- under Snow Leopard, which ignores my old cron file.
You could try Auto Scheduled Task for Mac http://www.readmesoft.com/mac
Run an application, open a file, or apple script, automator workflow by schedule
It's a GUI tool and easy to use:
Have a look at Task Till Down.
How about Crontooie, a GUI frontend for cron:
There is also Scheduler for Mac at www.macscheduler.net. I am the developer of it. :) User feedback is appreciated. And one more thing... It's free.
