Functions ¶
func CheckMode ¶
CheckMode check input file mode whether includes invalid mode. For example, if read operation of group and other is forbidden, then call CheckMode(inputFileMode, 0044). All operations are forbidden for group and other, then call CheckMode(inputFileMode, 0077). Write operation is forbidden for group and other by default, with calling CheckMode(inputFileMode)
func CheckOwnerAndPermission ¶
CheckOwnerAndPermission check path owner and permission
func CheckPassWordComplexity ¶
CheckPassWordComplexity check password complexity
func GetDriverLibPath ¶
GetDriverLibPath get driver lib path from ld config
func GetSha256Code ¶
GetSha256Code return the sha256 hash bytes
func IsExist ¶
IsExist check whether the path exists, If the file is a symbolic link, the returned the final FileInfo
func IsLexist ¶
IsLexist check whether the path exists, If the file is a symbolic link, the returned FileInfo describes the symbolic link
func IsNil ¶
func IsNil(i interface{}) bool
IsNil check whether the interface is nil, including type or data is nil
func IsSoftlink ¶
IsSoftlink check whether the path is softlink
func MakeSureDir ¶
MakeSureDir create directory. The last element of path should end with slash, or it will be omitted.
