I just read this:
Disable printing of fonts/packages to STDOUT
and I was wondering whether the same could be effected somehow from the .tex file being compile (probably you would want to do this before the \documentclass, or at least before all of the \usepackages).
\batchmodebefore\documentclasswill suppress everything except the initial banner. – egreg Jun 28 '14 at 07:56arara. – cfr Jun 28 '14 at 17:42
