Google is your friend.
There is no definite answer because it depends on the kind of shader that you want to use. Your main choices are surface shaders in Cg/HLSL, vertex and fragment shaders in Cg/HLSL, vertex and fragment shaders in GLSL. I’d recommend my wikibooks for the latter two options (but I’m biased): http://en.wikibooks.org/wiki/Cg_Programming/Unity and http://en.wikibooks.org/wiki/GLSL_Programming/Unity . For surface shaders, you should read the Unity documentation http://docs.unity3d.com/Documentation/Components/SL-SurfaceShaders.html , however, that documentation assumes that you know Cg/HLSL and you have a basic understanding of how GPUs work and you should also know a fair bit of ShaderLab syntax as explained here: http://docs.unity3d.com/Documentation/Components/SL-Shader.html
