Functions

func Chdir

func Chdir(dir string) error

Chdir changes the current working directory to the named directory. If there is an error, it will be of type *PathError.

func Chmod

func Chmod(name string, mode os.FileMode) error

Chmod changes the mode of the named file to mode. If the file is a symbolic link, it changes the mode of the link's target. If there is an error, it will be of type *PathError.

func Chown

func Chown(name string, uid, gid int) error

Chown changes the numeric uid and gid of the named file. If the file is a symbolic link, it changes the uid and gid of the link's target. If there is an error, it will be of type *PathError.

func Chtimes

func Chtimes(name string, atime time.Time, mtime time.Time) error

Chtimes changes the access and modification times of the named file, 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 Create

func Create(name string) (*os.File, error)

Create creates the named file with mode 0666 (before umask), truncating it if it already exists. If successful, methods on the returned File can be used for I/O; the associated file descriptor has mode O_RDWR. If there is an error, it will be of type *PathError.

func Lchown

func Lchown(name string, uid, gid int) error

Lchown changes the numeric uid and gid of the named file. If the file is a symbolic link, it changes the uid and gid of the link itself. If there is an error, it will be of type *PathError.

func Link

func Link(oldname, newname string) error

Link creates newname as a hard link to the oldname file. If there is an error, it will be of type *LinkError.

func Lstat

func Lstat(name string) (os.FileInfo, error)

Lstat returns a FileInfo describing the named file. If the file is a symbolic link, the returned FileInfo describes the symbolic link. Lstat makes no attempt to follow the link. If there is an error, it will be of type *PathError.

func Mkdir

func Mkdir(name string, perm os.FileMode) error

Mkdir creates a new directory with the specified name and permission bits. If there is an error, it will be of type *PathError.

func MkdirAll

func MkdirAll(path string, perm os.FileMode) error

MkdirAll creates a directory named path, along with any necessary parents, and returns nil, or else returns an error. The permission bits perm are used for all directories that MkdirAll creates. If path is already a directory, MkdirAll does nothing and returns nil.

func NewFile

func NewFile(fd uintptr, name string) *os.File

NewFile returns a new File with the given file descriptor and name.

func Open

func Open(name string) (*os.File, error)

Open opens the named file for reading. If successful, methods on the returned file 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 OpenFile

func OpenFile(name string, flag int, perm os.FileMode) (*os.File, error)

OpenFile is the generalized open call; most users will use Open or Create instead. It opens the named file with specified flag (O_RDONLY etc.) and perm, (0666 etc.) if applicable. 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 Readlink

func Readlink(name string) (string, error)

Readlink returns the destination of the named symbolic link. If there is an error, it will be of type *PathError.

func Remove

func Remove(name string) error

Remove removes the named file or directory. If there is an error, it will be of type *PathError.

func RemoveAll

func RemoveAll(path string) error

RemoveAll removes path and any children it contains. It removes everything it can but returns the first error it encounters. If the path does not exist, RemoveAll returns nil (no error).

func Rename

func Rename(oldpath, newpath string) error

Rename renames (moves) a file. OS-specific restrictions might apply. If there is an error, it will be of type *LinkError.

func Stat

func Stat(name string) (os.FileInfo, error)

Stat returns a FileInfo describing the named file. If there is an error, it will be of type *PathError.

func Symlink

func Symlink(oldname, newname string) error

Symlink creates newname as a symbolic link to oldname. If there is an error, it will be of type *LinkError.
