Maya CLI
From wikinotes
mayabatch
Mayabatch gives you complete command-line access to maya. As long as a module does not require the GUI, it can be run.
C:/Program Files/Autodesk/Maya2015/bin/mayabatch.exe -file "C:/myFile" -command "source ""C:/some/file.mel""; "
render
Maya provides the render executable to perform renders from the command-line. It is fairly comprehensive, but outshone by mayabatch, which can run full-on mel/python scripts.
