Mac os x launchctl unload

The problem is these are not present in the launchagents directory or in the launchdaemons directory. So my question is how to find the path for these daemon services. Then next step is how to stop these.

Since some of these could start again and again based on certain flags. If you want to stop the item for this boot simply issue an unload command to launchd via launchctl. The man page for launchctl has nice documentation for controlling jobs. You can do a "launchctl dumpstate" and it will show all the loaded services and the path to the startup.

How to remove service from launchd using launchctl Hello I have removed an application called "Internet Everywhere" and noticed that my computer at start-up tried to launch this service anyways. Internet Everywhere appears as a service with status "1" in launchctl list. I tried to initially using launchctl remove "Internet Everywhere" and the answer was that there was no such service. The I tried using launchctl unload and still no success: Dubious ownership on file skipping: Can you help me understanding what I have to do to remove this service?

Best regards Valentin. More Less. Helpful answers Drop Down menu. View answer in context. Topher Kessler Topher Kessler. To unload the file, you will need to know the path to the. The following job is run every day at 3: Some intervals are very tedious to specify in launchd.

Mac OS X: Loading and Unloading with launchd

Users familiar with cron know that there is a more elegant way to specify such intervals. A quick example: You want to run a program every five minutes between In launchd you have to list all 36 matching timestamps like this:. LaunchControl allows you to generate this list from the equivalent cron-style specification: The following description of the cron time specification was taken from the cron manual page:.

Ranges of numbers are allowed. Ranges are two numbers separated with a hyphen. The specified range is inclusive. For example, for an "hours" entry specifies execution at hours 8, 9, 10 and Lists are allowed. A list is a set of numbers or ranges separated by commas. Step values can be used in conjunction with ranges. Unlike cron which skips job invocations when the computer is asleep, launchd will start the job the next time the computer wakes up. If the path points to a directory, creating and removing this directory, as well as creating, removing and writing files in this directory will start the job.

Actions performed in subdirectories of this directory will not be detected. Whenever one of the directories specified is not empty, the job will be started. It is the responsibility of the job to remove each processed file, otherwise the job will be restarted after ThrottleInterval seconds. This is the most basic setting. A value of true will run the job as soon as the job definition is loaded and restart it should it ever go down. If you configure your job to be kept alive 'no matter what', launchd will run the job immediately after loading it.

When a job terminates it can set a numeric return value, its exit status. By convention an exit status of 0 is used when the program exited successfully. Any other number informs about a problem. The subkey SuccessfulExit can be used to restart your program depending on its previous exit status. When set to true the job will be restarted until it fails.

Setting this value to false will restart the job until it succeeds. If this subkey is specified, launchd will run the job immediately after loading.

To avoid this behaviour set the subkey AfterInitialDemand. The subkey Crashed can be used to restart your program after it has crashed. When set to true the job will be restarted after it crashed. Setting this value to false will restart the job unless it has crashed. Use this subkey to keep a job alive as long as a given path exists true or does not exist false. The name of this subkey is somewhat misleading. It does not check if a certain job is enabled, but if a job is loaded.

The following job will be started and restarted when a job with label local. It will be terminated when a job with label local. Always specify the Label of the job you are referring to, not the name of the job definition file. If set, these keys will be ignored until the job has been started manually.

Using the keys UserName and GroupName you can specify as which user the job should run. The key InitGroups specifies if launchd should call the function initgroups 3 before starting the job. Using this key you can specify which permissions a file or folder will have by default when it is created by this job. The value is expected to be a decimal number. In the following example we specify that new files should be readable and writable by the user owning the file.

In addition new directories should be searchable by the user. Group members should be able to read new files and search created directories. Others should not be able to access new files or directories at all. First you have to come up with three digits between 0 and 7. The first one defines user access, the second one group access and the third one world access. We want read, write and search permissions for the user: We want read and search permissions for the group: We want no access at all for everyone else: The last step is to convert this octal number to its decimal representation.

We'll use the bc command line tool to do that:. LaunchControl saves you the trouble of coming up with a bit mask and converting it to decimal. Just select the bits you'd like to set. Every selected bit is a revoked permission. This key will be ignored when specified for an agent. Using this key you can execute the job in a chroot 2 jail. As far as the job is concerned, the directory provided with this key is the root of the filesystem. This implies that you need copies of all files required for the job inside this directory. This includes libraries, frameworks, command line tools and configuration files.

Setting the value of this key to true will stop this propagation, allowing the child processes to survive their parents. This key may me used in combination with KeepAlive to run a job every n seconds while a certain condition applies. This key controls the behavior of timers created by the job. By default on OS X Mavericks version Batching the firing of timers with similar deadlines improves the overall energy efficiency of the system.

If this key is set to true, timers created by the job will opt into less efficient but more precise behavior and not be coalesced with other timers. Run a job at an altered scheduling priority. Possible values range from to The default value is 0. Lower nice values cause more favorable scheduling.

This section explains how to acquire information about launchd jobs and how to load, unload, start and stop them. All of this can be accomplished using the command line utility launchctl , but you will see that it is far easier using LaunchControl.

    Exit Codes

    All examples refer to agents. Should you want to work with daemons you have to use sudo launchctl instead of launchctl. You will be prompted for the admin password when working with daemons. We will get some information about a job with Label com. We issue the command launchctl list , which returns a long list of currently loaded jobs. To search for our specific job with the label com.

    This results in a more detailed output in a JSON-like format. To find out if a job's Disabled key has been overridden we query the override database using the xpath command line utility. Its first argument is the name of the file to query, its second argument the query itself.

    You have to replace the job label in the query. You can enter the command as a single line by ommitting this character and the newline. We get a single hit, which means that the Disabled key is overridden. Its value is true. We would receive No nodes found if the key had not been overriden. We have already learned that launchd loads jobs automatically, daemons at boot time, agents when the user logs in.

    The following example loads the agent com. If this happens the job has either set the Disabled key to true or the job has been disabled in the override database. In either case you can force launchctl to load the job like this: Should the job be disabled or should the Disabled key be overridden in the override database the button will have its label changed to "Force Load" automatically.

    The following example unloads the agent com. Unloading a job with LaunchControl is similar to loading a job. When the currently selected job is loaded, the "Load" button will have its label changed to "Unload":. Sometimes you may want to start a job regardless of its run conditions. This section explains how to do that. You either misspelled the Label of the job or forgot to load it in the first place. When launchd is about to load a job it will check if it has the Disabled key set.

    Disabled jobs will not be loaded. But the value of this key can be overridden. OSX While you will always be able to switch a job's permanent status between enabled and disabled, you cannot trivially remove it from the override database again. The procedure is different for agents and daemons. You'll need the label of the job you want to remove.
