I just want to mention this:
I believe your use of the word "Batch" is different from LTspice's "Batch".? The word "Batch" has special meaning in LTspice, where it refers to running simulations that do not require human intervention because they run in the background.? I suspect you did not mean that (but maybe you did?).
LTspice's "batch" mode is activated by adding "-b" to the command-line.? Also with the "-FastAccess", "-netlist", or "-PCBnetlist" command-line switches.
LTspice's "batch" comes from MS-DOS's "batch" where programs can be run and controlled from a .BAT (batch) file.
