My understanding is that SAGA can be accessed using the command line.

If you intend to create a bash script to dissolve your shapefiles, it
would be just as easy I presume to write a script that opens the
shapefile, dissolves the polygons, then closes it; progressively working
through the list of counties. Remember most packages have the ability to
run script. gvSIG uses Jpython, QGIS python, etc. I fact from what I can
tell you can actually import QGIS modules into python.
