There's no need to construct elaborate command lines to drive the process: just create a script file (say, "script.geo"), that contains the command Merge "file.step"; followed by any command you want, exactly in the same way as for "geo" geometries. You can even merge a STEP file interactively and use the GUI to add commands (like physical groups, for the solver). Gmsh will create the file for you, automatically. See e.g. demos/component8_in_a_box.geo for an example.
