If the current directory can be reached via multiple paths (due to symbolic links), Getwd may return any one of them. The string is guaranteed to be a rooted path, not containing any symbolic links. HasPrefix checks whether the string s begins with prefix. It returns true if s begins with prefix, false otherwise. HasSuffix checks whether the string s ends with suffix. It returns true if s ends with suffix, false otherwise. IsDir checks whether the path is a directory. It returns true if the path is a directory, false otherwise. IsFile checks whether the path is a regular file. It returns true if the path is a regular file, false otherwise. IsPathSeparator reports whether c is a directory separator character. IsPathSeparator returns true if c is os.PathSeparator or os.PathListSeparator. IsPathSeparator returns false otherwise. IsRooted reports whether the path is rooted. IsRooted returns true if the path is rooted (
