Just short question: what's the equivalent in latex of \ctxlua{context(os.resultof("sha256sum \jobname.conTeXt | cut -c -5"))}

\documentclass{article} \begin{document} \directlua{ local handle = io.popen("sha256sum \jobname.tex | cut -c -5","r") if handle then local result = handle:read("*all") or "" handle:close() tex.print(result) end } \end{document} or load l-os.lua, then the command os.resultof is available. Herbert
