All Gmsh options can be set from the command line (using e.g. '-setnumber 
OptionName value' for numeric options); some popular options also have 
shortcuts. See the reference manual for the extensive list.

So if you want to scale the mesh size from the command line you could e.g. do

gmsh file.geo -3 -clscale 1
gmsh file.geo -3 -clscale 0.5
gmsh file.geo -3 -clscale 0.25
