launchctl: Manually run a known (loaded) agent/daemon, even if it is not the right time (note: this command uses the agent's label, rather than the filename).
$ launchctl start ${script_file}
try on your machine

The command launchctl start ${script_file} is used to start a launchd job in macOS. Here's an explanation of each part of the command:

  • launchctl: This is the command-line utility used to load, unload, and manage launchd jobs in macOS. launchd is a system process that manages various daemons, agents, and scripts on the system.

  • start: This is the subcommand of launchctl that instructs launchd to start a specified job. It initiates the job and launches the associated process.

  • ${script_file}: This is a placeholder variable that represents the file path or label of the launchd job script that you want to start. You would replace ${script_file} with the actual name or path of the script file you wish to run.

In summary, the command launchctl start ${script_file} tells launchd to start the specified job, which is represented by the ${script_file} variable. This is commonly used in macOS to start daemons, agents, or any other background processes managed by launchd.

This explanation was created by an AI. In most cases those are correct. But please always be careful and never run a command you are not sure if it is safe.
