Functions ¶

func Arg ¶

func Arg(n int) string

Arg gets the nth argument from os.Args, or an empty string if os.Args is too short.

func CreateNew ¶

func CreateNew(path string, zeroByte bool) (*os.File, error)

CreateNew creates a new file.

An error is returned if the file already exists, unless zeroByte is set it's a zero-byte file. Note that this is subject to race conditions, and not suitable if multiple processes may create the same file.

func Readable ¶

func Readable(s os.FileInfo) (bool, error)

Readable reports if the file is readable by the current user.

func Writable ¶

func Writable(s os.FileInfo) (bool, error)

Writable reports if the file is writable by the current user.

Types ¶

type Permission ¶

type Permission struct {
	Read    bool
	Write   bool
	Execute bool
}

type Permissions ¶

type Permissions struct {
	User  Permission
	Group Permission
	Other Permission
}

func ReadPermissions ¶

func ReadPermissions(mode os.FileMode) Permissions

ReadPermissions reads all Unix permissions.
