Functions

func DirFileCount

func DirFileCount(dirPath string) (int, error)

func DirSizeOnDisk

func DirSizeOnDisk(dirPath string, withNonDirPrefix bool) (uint64, error)

- on-disk size is sometimes referred to as "apparent size" - NOTE: ignore exec error: `du` exits with status 1 if encounters non-regular file that can't be accessed (perm) - `withNonDirPrefix` is allowed to match nothing

func DirSumFileSizes

func DirSumFileSizes(dirPath string) (uint64, error)

func FinfoAtime

func FinfoAtime(fqn string) (finfo os.FileInfo, atime int64, err error)

func GetATime

func GetATime(osfi os.FileInfo) time.Time

func GetFSStats

func GetFSStats(path string) (blocks, bavail uint64, bsize int64, err error)

func GetFSUsedPercentage

func GetFSUsedPercentage(path string) (usedPercentage int64, ok bool)
