At the point your process stopped, it's barely begun. The file in /tmp
will contain something like

\nonstopmode
\documentclass[a4paper]{article}
\begin{document}
\typeout{textwidth=\the\textwidth}
\typeout{columnsep=\the\columnsep}
address@hidden
\end{document}

and normally it disappears in a flash. (I had to run
while : ; do cat /tmp/tmp*.tex ; done
in a captured session just to find that out.)

The clue as to why it gets no further is in the error message.
The bash functions I actually use to run LP and TeX keep things simple
by changing into the appropriate directories, so start with everything
in /tmp. Then change one thing at a time.

Here's an example run of mine, using just the naked commands. I've
inserted blank lines before each prompt (which prints the current
directory):

/tmp $ cat boo.lytex
\documentclass[a4paper]{article}
\begin{document}
Documents for \verb+lilypond-book+ may freely mix music and text.
For example,
\begin{lilypond}
\relative {
  c'2 e2 \tuplet 3/2 { f8 a b } a2 e4
}
\end{lilypond}
\lilypondfile[quote,noindent,line-width=15\cm]{bigger.ly}
\end{document}

/tmp $ cat bigger.ly
{ c' d' e' f' g' a' b' c'' g c' e' g' c'' e'' g'' c''' }
