type HostCmd

type HostCmd struct {
	// contains filtered or unexported fields
}

HostCmd allows to run a command on the host By default, when the command is run it does not print any output generated during execution. See Silent, Stdin, RunWithEcho, RunAndCapture, Skip and DryRun for possible variations to the default behavior.
