You can determine whether your launch daemon is presently operational on macOS using programming by checking if the daemon process is running. One way to do this is to use the ps
command in terminal to list all running processes on the system and then search for your daemon process by name. Here's an example code snippet in Swift:
import Foundation
func isDaemonRunning() -> Bool {
let task = Process()
task.launchPath = "/bin/ps"
task.arguments = ["axo", "comm"]
let pipe = Pipe()
task.standardOutput = pipe
task.launch()
task.waitUntilExit()
let data = pipe.fileHandleForReading.readDataToEndOfFile()
let output = NSString(data: data, encoding: String.Encoding.utf8.rawValue)!
return output.contains("your-daemon-process-name")
}
This code creates a new Process
instance and sets its launchPath
to /bin/ps
which is the path of the ps
command. The arguments
array specifies the arguments to pass to the command which in this case are axo
and comm
, which tell ps
to list all processes (a
), show only the command name (comm
), and output the data in a specific format (x
).
The code then creates a pipe for capturing the standard output of the process and sets it to the task.standardOutput
property. It launches the process, waits for it to complete, and reads the output from the pipe as a string.
Finally, it returns a boolean value indicating whether the output string contains the name of your daemon process. If it does, then the daemon is currently running, otherwise it is not.
