comment How to trigger UNIX command-line command from Mathematica notebook?
The UNIX system call that waits for an external process to finish running (appropriately called wait()) actually yields a value that is the process's exit code shifted left by 8 bits, assuming the process exited normally. Normally you never see this value, because most programs (including a shell) reverse the leftward bit shift, but I guess Mathematica doesn't (whether to provide complete information about the exit status, or just because of a bug, I don't know). That's probably why you get 32512.

comment How do I eliminate the breaks in a 3D plot with a Max or Min function?
@kguler done, although are you sure? I do think in its current form it's certainly a good answer.

Ah, this is indeed a duplicate. I didn't find that question when I was looking for prior work.

Version 8 on Linux (Gentoo). Let me try v7 and v9 (if I can get it to work) to see if it does the same.

comment Adding multiple Complex Numbers in Euler form
Well, it is lowercase $i$ in standard mathematical notation, but uppercase I or [Esc]i[Esc] in Mathematica syntax. (I think the current version of the question is actually unclear for this reason, though it's a minor thing.)

comment Adding multiple Complex Numbers in Euler form
OK, but then what result are you looking for? What sort of simplification do you expect Mathematica to make? (Note that this sum can't be written as a single term of the form $Re^{i\theta x}$, if that's what you had in mind.)
