Functions

func MutuallyExclusiveBoolError

func MutuallyExclusiveBoolError(inputE error, values ...bool) (bool, error)

returns true and the given error, if more then one value is true

func Sync

func Sync(input *Input) (exitCode uint8)

Synchronize all filesystems or a file.

func Synchronize

func Synchronize(input *Input, output abstract.OutputInterface) (exitCode uint8)

Synchronize all filesystems or a file.

According to the standard specification (e.g., POSIX.1-2001), sync() schedules the writes, but may return before the actual writing is done. However Linux waits for I/O completions, and thus sync() or syncfs() provide the same guarantees as fsync called on every file in the system or filesystem respectively.

Types

type Input

type Input struct {
	abstract.Input

	PathList []string

	// sync only file data, no unneeded metadata
	Data bool

	// sync file
	File bool

	// [not implemented] sync the file systems that contain the files
	FileSystem bool
}
