Hi all, (for reference: original discussion: https://github.com/rstudio/tinytex/issues/427) in TeX Live we are using runscript.lua https://tug.org/svn/texlive/trunk/Master/bin/windows/runscript.tlu?revision=68820&view=markup to resolve scripts, typical examples are fmtutil -> fmtutil.pl updmap -> updmap.pl etc (not only for perl scripts!). It seems that in some cases, the scripts fails to resolve scripts, for example fmtutil-sys will use Windows "short name" passed in, like "FMTUTI~1.EXE" My question: Is there a way in luatex to convert these short names to "proper" (= long) names?
