How to execute shell script from LaTeX? [closed]

Answer 1

I don't think this is possible. I would use a simple preprocessor for that. I.e. change the document to

\documentclass{article}
\begin{document}
%%OUTPUT%%
\end{document}

and preprocess it with

#!/usr/bin/perl -lp
BEGIN { $output = `/usr/local/bin/my-shell-script.sh`; }
s/%%OUTPUT%%/$output/g;

Command:

perl so.pl template.tex > preprocessed.tex

or in-place:

perl -i so.pl template.tex
