The "-u" flag only works for the root user. Maybe you can have a condition in your shell script and use the "-u root" option only when appropriate. Thomas On Dec 22, 2011, at 10:29 AM, Nandini Vijayashankar wrote:

Hi,

Thanks a lot... Its working from root user login. If I use the same command from non-root user login, iam getting error. I used: launchctl -u <username> unload /System/Library/LaunchAgents/<plistfile> Unknown user:<username>

I want to use a generic command from my shell script to unload the plist file which is applicable for both root and non-root user login. Is it possible?

Thanks

You should try: launchctl -u root unload /System/Library/LaunchAgents/<plistfile>

Hi,

I want to know how does launchd start the user defined launchagents service when a "root" user logs in to the system.

Iam using Mac 10.6

I have a launchdaemon and launchagent present in /System/Library/LaunchDaemons and /System/Library/LaunchAgents.

When I login with a non-root user, my launchagent service is started as that logged in user. I can unload this service using "launchctl unload /System/Library/LaunchAgents/<plistfile>"

If I login as root user,my launchagent service is started and working fine.But its not started as logged in user ie., root. If I try to unload through "launchctl unload /System/Library/LaunchAgents/<plistfile>" I get error: launchctl : Error unloading <id>

This is because the service is not launched as root user.

Above scenarios are working fine in Mac 10.5 as root and non-root user.

When i see my launchagent service in Activity monitor, the parent process is the per-user launchd instance. The parent process of this launchd is system launchd with pid 1.

I have tried to list the service using various commands: launchctl list launchctl bslist sudo launchctl list

All these are not showing my launchagent service.Is there any special way, launchd launches launchagents service when a root user logs in Mac 10.6?

How can i unload my launchagent service when the root user logs in?
