Rotate Object from Other Local Object

Question

is there a way to rotate an object, on the current local axis of an other object?

something (this is not right) like this: transform.Rotate(-5,0,0,Space.GameObject.Find("OtherObject"));

Rotations are always tricky. If both objects have the same rotation at Start and have no parents, you can copy transform.rotation from one object to the other - the second object will follow any rotation applied to the first one. If they are childed to other objects, however, you may have lots of weird effects.

EDITED: There is a function to rotate an object around any arbitrary axis, RotateAround. You can set this axis to some local vector of another object: use .up vector for Y, .right for X or .forward for Z.
It's not possible to rotate around more than one axis in a single RotateAround.
The example below rotate around the Y axis of the object defined in master:

 var master: Transform; // reference object
 
 function Update(){
 
     var ang = Input.GetAxis("Horizontal") * 30 * Time.deltaTime;
     transform.RotateAround(transform.position, master.up, ang);
 }

Do you mean Transform.localRotation ? The rotation of the transform relative to the parent transform's rotation. If so ,just change its value.

I mean that you can rotate an object like on the X axis en when you turn an other object, that it will twist object 1 on the local X as of object 2
