Algorithm (Workflow)
The function whoisPID is designed to interact with processes on macOS systems. It takes a process identifier (PID) or a service name and an optional command to perform specific actions.
Input Parameters
- PID: This can be a numeric process ID or a string representing a service name in the list of launched tasks.
- cmd: An optional string parameter that can specify actions like 'remove' or 'unload'.
Algorithm Steps
- Add paths to
/Library/LaunchAgents and /Library/LaunchDaemons to the MATLAB search path.
- Retrieve the command parameter using
getfuncparams function.
- Check if
PID is numeric:
- If numeric, construct a command string
s using ps auxww to get detailed information about the process.
- If
PID is a string (service name):
- Construct a command string
s using launchctl list to list the service.
- Check if
cmd is 'remove':
- Modify the command string
s to use launchctl remove to remove the service.
- Check if
cmd is 'unload':
- Ensure the
PID ends with .plist. If not, append it.
- Find the full path of the
PID using which.
- Modify the command string
s to use launchctl unload to unload the service.
- Remove the previously added paths from the MATLAB search path.
- Execute the constructed command string
s using the system function.
