BashWithArgs executes a shell command with arguments and returns its standard output

func ConvertNodeName

func ConvertNodeName(node string) string

ConvertNodeName e.g.(10.23.10.12 => 10-23-10-12)

func ConvertShellOutputs

func ConvertShellOutputs(outputs string) []string

ConvertShellOutputs splits shell output string into a slice of strings, one per line

func ExecCmd

func ExecCmd(command, args string) (out []byte, err error)

ExecCmd executes a shell command with arguments as a single string and returns its output

func FoundNewStringElems

func FoundNewStringElems(old, new []string) ([]string, bool)

FoundNewStringElems compare two arrays, find if there is new elem in new array

func FuncName
