I want to schedule events for exact times in Mac OS X. It seems like the 'at' command is the simplest way to do this.
I have enabled atrun using the command:
launchctl load -w /System/Library/LaunchDaemons/com.apple.atrun.plist
To test at, I'm using the following one-line BASH script:
echo 'foo' >> path/to/log.txt | at now + 2 minutes
When I run the script, I get output like:
job 17 at Sat May 15 12:57:00 2010
where '12:57:00' is indeed 2 minutes in the future. But the echo command executes immediately: the line 'foo' is added to log.txt right away.
How can I make at work for me?
