Functions ¶

func CopyFile ¶

func CopyFile(src, dst string) (int64, error)

CopyFile copies from src to dst until either EOF is reached on src or an error occurs. It verifies src exists and removes the dst if it exists.

func CreateIfNotExists ¶

func CreateIfNotExists(path string, isDir bool) error

CreateIfNotExists creates a file or a directory only if it does not already exist.

func GetTotalUsedFds ¶

func GetTotalUsedFds() int

GetTotalUsedFds returns the number of used File Descriptors by executing "lsof -lnP -Ff -p PID".

It uses the "-F" option to only print file-descriptors (f), and the "-l", "-n", and "-P" options to omit looking up user-names, host-names, and port- names. See LSOF(8).

func ReadSymlinkedDirectory ¶

func ReadSymlinkedDirectory(path string) (realPath string, err error)

ReadSymlinkedDirectory returns the target directory of a symlink. The target of the symbolic link may not be a file.
