func Walk ¶

func Walk(root string, walkFn func(path string, typ os.FileMode) error) error

Walk walks the file tree rooted at root, calling walkFn for each file or directory in the tree, including root.

If Walk returns filepath.SkipDir, the directory is skipped.

Unlike filepath.Walk:

• file stat calls must be done by the user. The only provided metadata is the file type, which does not include any permission bits.
• multiple goroutines stat the filesystem concurrently. The provided walkFn must be safe for concurrent use.
• Walk can follow symlinks if walkFn returns the TraverseLink sentinel error. It is the walkFn's responsibility to prevent Walk from going into symlink cycles.
