Hey I’m new at playing around with Shaders - did I search and could not find what I was looking for.
I downloaded some 3d meshes that come with texture maps for diffuse, normal, and specular. I see in Unity there is a shader for bumped diffuse and also a shader for bumped specular.
Is there a shader for bumped diffuse specular?
I’m not sure what I’m asking even makes sense!
Thanks for any help.

Oh I see what you’re after. The alpha of the main texture is used in most of the shaders as a gloss/specular amount. I think that’s what you’re wanting, I saw a thread once asking about specular textures, not sure if it’s the same thing (I think one of the Unity devs made one in response).
Edit: Ok ignore me, I’d just woken up and wasn’t reading things properly, my mistake. Anyway yeah the bumped specular is bumped diffuse just with the specular added to it, which you can lower to nothing and it’s the same as bumped diffuse and also as mentioned, control with the base alpha as the gloss. Ok, think I read the post properly this time, sorry again. 
what about something like this?

I posted something here about it. It’s a good starting point, simply follow the “remove alpha” instruction at the bottom of the thread.
Well depending on what you need for specular. The “bumped specular” uses the alpha channel of the diffuse as a grayscale specular map. If you want coloured specular maps you’ll either have to modify the shader yourself. Or you can use the look into solutions like Strumpy shader lab, in which case I believe alexandre’s link actually contains a version of that. (Read the update with information on how to remove transparency if not needed. I didn’t look at the actual shader but it should be faster.)
