func ExecuteCommand ¶ added in v0.0.6

func ExecuteCommand(ctx context.Context, cmd *exec.Cmd) error

ExecuteCommand executes a command and and prints the output to stdout. It will not return until the command has completed or the context is cancelled.

NOTE: If you want the command to continue even if the parent is killed (e.g. through a signal like SIGINT) you will want to launch the command in a new process group so that signals are not sent to the child process.

cmd.SysProcAttr = &syscall.SysProcAttr{
	Setpgid: true,
}

func ExecuteCommandAndRelease ¶ added in v0.0.19

func ExecuteCommandAndRelease(ctx context.Context, cmd *exec.Cmd) error

ExecuteCommandAndRelease will execute the given command and release all associated resources so that it will continue to run even if the caller is terminated.

NOTE: You probably want to launch the command in a new process group to avoid signals (e.g. SIGINT) being sent to the child process.

cmd.SysProcAttr = &syscall.SysProcAttr{
	Setpgid: true,
}
