Functions

func AppendAll

func AppendAll(dst string, src string) error

AppendAll creates or appends the dst file or dir, filled with content from src file. If the dst file already exists, it is truncated. If the dst file does not exist, it is created with mode 0666 (before umask). If the dst dir does not exist, it is created with mode 0755 (before umask).

func ChtimesNow

func ChtimesNow(name string) error

Chtimes changes the access and modification times of the named file with Now, similar to the Unix utime() or utimes() functions.

The underlying filesystem may truncate or round the values to a less precise time unit. If there is an error, it will be of type *PathError.

func CopyAll

func CopyAll(dst string, src string) error

CopyAll creates or truncates the dst file or dir, filled with content from src file. If the dst file already exists, it is truncated. If the dst file does not exist, it is created with mode 0666 (before umask). If the dst dir does not exist, it is created with mode 0755 (before umask).

func CopyFile

func CopyFile(dst string, src string, flag int, perm os.FileMode) error

CopyFile copies from src to dst. parent dirs will not be created, otherwise, use CopyFileAll instead.

func CopyFileAll

func CopyFileAll(dst string, src string, flag int, dirperm, fileperm os.FileMode) error

CopyFileAll is the generalized open call; most users will use CopyAll or AppendAll instead. It opens the named file or directory with specified flag (O_RDONLY etc.). If the dst file does not exist, and the O_CREATE flag is passed, it is created with mode fileperm (before umask). If the dst directory does not exist,, it is created with mode dirperm (before umask). If successful, methods on the returned File can be used for I/O. If there is an error, it will be of type *PathError.

func CreateAll

func CreateAll(path string) (*os.File, error)

CreateAll creates or truncates the named file or dir. If the file already exists, it is truncated. If the file does not exist, it is created with mode 0666 (before umask). If the dir does not exist, it is created with mode 0755 (before umask).

func CreateAllIfNotExist

func CreateAllIfNotExist(path string) (*os.File, error)

CreateAllIfNotExist creates the named file or dir. If the file does not exist, it is created with mode 0666 (before umask). If the dir does not exist, it is created with mode 0755 (before umask). If path is already a directory, CreateAllIfNotExist does nothing and returns nil.

func GetAbsBinDir

func GetAbsBinDir() (dir string, err error)

func OpenAll

func OpenAll(path string) (*os.File, error)

OpenAll opens the named file or dir for reading. If successful, methods on the returned file or dir can be used for reading; the associated file descriptor has mode O_RDONLY. If there is an error, it will be of type *PathError.

func OpenFileAll

func OpenFileAll(path string, flag int, dirperm, fileperm os.FileMode) (*os.File, error)

OpenFileAll is the generalized open call; most users will use OpenAll or CreateAll instead. It opens the named file or directory with specified flag (O_RDONLY etc.). If the file does not exist, and the O_CREATE flag is passed, it is created with mode fileperm (before umask). If the directory does not exist,, it is created with mode dirperm (before umask). If successful, methods on the returned File can be used for I/O. If there is an error, it will be of type *PathError.

func PathExists

func PathExists(path string) (bool, error)

func SameFile

func SameFile(fi1, fi2 string) bool

SameFile reports whether fi1 and fi2 describe the same file. Overload os.SameFile by file path

func TouchAll

func TouchAll(path string) (*os.File, error)

TouchAll creates the named file or dir. If the file already exists, it is touched to now. If the file does not exist, it is created with mode 0666 (before umask). If the dir does not exist, it is created with mode 0755 (before umask).
