OK.  Your desire is to learn how to drive a simulator using the CLI.
You want to do it on Linux.  You are already familiar with LTSpice, so
I won't recommend that you go that route.

Your problem is that you want to plot your simulations results.  Here
are some options.  Important caveat:  I haven't tried any of them, but
I have indeed heard about them.  Also, each of these projects is
better maintained than gwave, which is (unfortunately) more or less
dead.

*  If you use ngspice for simulation, you can use an Octave plug-in to
plot your results using Octave.  (Octave is an open-source MATLAB
equivalent.) Here's a link:

http://ngspice.sourceforge.net/octavespice.html

If Gnucap exports .raw files, then you could go this route with Gnucap
also.  Al, does Gnucap export .raw?

*  KJWaves.  You've read the flames, here's a link to using the tool
with ngspice:

http://ngspice.sourceforge.net/kjwaves.html

KJWaves does require that you pre-install a Java virtual machine on
your Linux box.  A lot of people don't like this for political
reasons, but YMMV.  Another reason to not like it is that Java is a
whole 'nother dependecy which can be difficult to install itself.  But
if you've already got Java running, then why not try it?

*  Oregano.  This is another front-end to both ngspice and Gnucap,
providing plotting and a nice GUI to drive the simulation.  You'll
spend plenty of time hand-twiddling your netlist, so don't worry that
the GUI is in your way.

http://arrakis.gforge.lug.fi.uba.ar/

*  QUCS.  This is really more of an entire simulation system with
options to perform various analog, RF, and maybe digital simulations.
I don't know how far along it is, or how easy it is to use.

http://qucs.sourceforge.net/


Personally, I'd give octavespice a try, since Octave is a powerful
environment for numerical analysis, and using Octave alongside
Gnucap/ngspice would make a powerful design combo.

Cheers,

Stuart
