Functions

func BufferCat

func BufferCat(sv ...string) []byte

BufferCat todo

func ByteCat

func ByteCat(sv ...[]byte) string

ByteCat cat strings: You should know that StrCat gradually builds advantages only when the number of parameters is> 2.

func DecodeUID

func DecodeUID(glid string) int64

func Du

func Du(path string) (int64, error)

func ErrorCat

func ErrorCat(sv ...string) error

ErrorCat todo

func ExpandPath

func ExpandPath(path string) string

ExpandPath is a helper function to expand a relative or home-relative path to an absolute path.

eg. ~/.someconf -> /home/alec/.someconf

func HumanateSize
