WatchPaths

All, I apologize if this is something that I could have found in the documentation but I'm not seeing it. Additionally, I couldn't find a better place to pose this question than launchd-dev, and this is really more of an end-user question. For a launch agent with multiple watch paths, how does one pass the path that fired the event to the program arguments? Thank you kindly!

unloading user jobs as root
by Tamás Lustyik - NTRglobal 16 Feb '10

Hi, I'm having trouble with unloading jobs launched from /Library/LaunchAgents and since I haven't had success in googling around I decided to ask for help here. I have an agent application which should run in the LoginWindow and Aqua contexts. A proper plist file has been created and works fine, the job loads and unloads automagically when the different sessions are entered/left. Now, the problem is with uninstallation. I have a separate uninstaller application which, at some point, is elevated to have root privileges to perform removal of files etc. Unfortunately, when running as root, launchctl does not seem to access the session of the logged in users, thus making it impossible to unload these already active jobs. I suppose calling launchctl as a regular user wouldn't work either for user sessions other than the current one. Can anyone give me pointers how to solve this? I do have read the Daemonomicon and also the list archives of last year but I might have missed the answer. Thanks, Tamas Lustyik

launch_msg(): Socket is not connected error in Leopard
by Arun 16 Feb '10

Hi All, I have a setup in which when the Mac reboots, i will be launching a script through launchd. This daemon writes multiple plist files in /Library/LaunchAgents and tries to load the same for all the users currently logged in. The loading of the agents is failing with "launch_msg(): Socket is not connected". However if i run the script in Terminal as root user, the error does not come. Any idea why this is happening with launchd triggered script? Thanks Arun KA

Help in launching a launch daemon
by Arun 05 Feb '10

05 Feb '10

Hi All, I am a newbie to launchd. I have a requirement to launch a system daemon whenever a file is created / modified. Also this daemon should not be launched multiple times, means even if the daemon crashes it should not be launched. Also this daemon shloud not be launched when the system starts. Can anyone help me in writing the launchd plist file satisfying the above. Thanks Arun KA
