Functions ¶

func DirFileCount ¶

func DirFileCount(dirPath string) (int, error)

func DirSizeOnDisk ¶

func DirSizeOnDisk(dirPath string) (uint64, error)

- on-disk size is sometimes referred to as "apparent size" - ignore errors since `du` exits with status 1 if it encounters a file that couldn't be accessed (permissions)

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)
