Types

type Executor

type Executor interface {
	// Exec executes program with args, and returns stdout if the return code is zero.
	// If nonzero, stderr is included in error.
	Exec(program string, args ...string) (string, error)
	// ExecLines is similar to Exec, except it splits the output on newlines. All empty
	// lines are discarded.
	ExecLines(program string, args ...string) ([]string, error)
}

Executor is a shim over cmd.Output() that allows for testing.
