Functions

func AbsPathToTilde

func AbsPathToTilde(absPath string) string

func CheckSubPath

func CheckSubPath(parent, sub string) (bool, error)

Check if sub is a subdirectory of parent

func DirEmpty

func DirEmpty(name string) (bool, error)

check name path is empty directory

func DirSize

func DirSize(path string) (int64, error)

same as du -B1 or du -sh The size is calculated as the disk space used by the directory and its contents, that is, the size of the blocks, in bytes (in the same way as the `du -B1` command calculates).

func DirSizeFallback

func DirSizeFallback(path string) (int64, error)

Look at both block-size and apparent-size and choose the larger one. Because there are file systems for which block size cannot be obtained. max(du -sB1, du -sb)

func FileHead

func FileHead(path string, width int, maxLines int) string

func FileType

func FileType(st fs.FileInfo) string

func IsBinary

func IsBinary(content io.ReadSeeker, fileSize int64) (bool, error)
