I'm trying to run a node script every hour on my Mac (OSX 10.8.2 Mountain Lion). According to high ranking search results, the best way to do this is to add a
launchd launch agent.
For some reason it doesn't seem to work.
I wrote the following launch agent file and saved it as
<?xml version="1.0" encoding="UTF-8"?> <!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd"> <plist version="1.0"> <dict> <key>KeepAlive</key> <dict> <key>SuccessfulExit</key> <false/> </dict> <key>Label</key> <string>protocol</string> <key>ProgramArguments</key> <array> <string>/usr/local/bin/node</string> <string>/Users/snorpey/PATH/TO/file.js</string> </array> <key>RunAtLoad</key> <true/> <key>StartInterval</key> <integer>3600</integer> </dict> </plist>
I started the launch agent by running
launchctl load ~/Library/LaunchAgents/agenttest.plist in the terminal.
I also made the script file executable with
sudo chmod -x /Users/snorpey/PATH/TO/file.js and updated the file permissions with
sudo chmod 777 /Users/snorpey/PATH/TO/file.js.
When I run
/usr/local/bin/node /Users/snorpey/PATH/TO/file.js in the terminal, the script works fine.
However, it doesn't seem to work when it's run by
launchd. I get the following messages in
Jan 15 22:32:46 snorpey com.apple.launchd.peruser.501 (agenttest): Exited with code: 1 Jan 15 22:32:46 snorpey com.apple.launchd.peruser.501 (agenttest): Throttling respawn: Will start in 10 seconds
Why does it fail to execute the script?
