# launchctl
|
||
|
||
> A command-line interface to Apple's `launchd` manager for launch daemons (system-wide services) and launch agents (per-user programs).
|
||
> `launchd` loads XML-based `*.plist` files placed in the appropriate locations, and runs the corresponding commands according to their defined schedule.
|
||
|
||
- Activate a user-specific agent to be loaded into `launchd` whenever the user logs in:
|
||
|
||
`launchctl load ~/Library/LaunchAgents/{{my_script}}.plist`
|
||
|
||
- Activate an agent which requires root privileges to run and/or should be loaded whenever any user logs in (note the absence of `~` in the path):
|
||
|
||
`sudo launchctl load /Library/LaunchAgents/{{root_script}}.plist`
|
||
|
||
- Activate a system-wide daemon to be loaded whenever the system boots up (even if no user logs in):
|
||
|
||
`sudo launchctl load /Library/LaunchDaemons/{{system_daemon}}.plist`
|
||
|
||
- Show all loaded agents/daemons, with the PID if the process they specify is currently running, and the exit code returned the last time they ran:
|
||
|
||
`launchctl list`
|
||
|
||
- Unload a currently loaded agent, e.g. to make changes (note: the plist file is automatically loaded into `launchd` after a reboot and/or logging in):
|
||
|
||
`launchctl unload ~/Library/LaunchAgents/{{my_script}}.plist`
|
||
|
||
- Manually run a known (loaded) agent/daemon, even if it isn’t the right time (note: this command uses the agent's label, rather than the filename):
|
||
|
||
`launchctl start {{my_script}}`
|
||
|
||
- Manually kill the process associated with a known agent/daemon, if it's running:
|
||
|
||
`launchctl stop {{my_script}}`
