How to run shell command with \write18?

Question

I want to use the command \write18 with shell or other excutables rather than only a restricted list of programs as it says here: https://tex.stackexchange.com/a/20446/92620

How can i bypass the restrictions set on \write18 to execute external/shell from documents ?

EDIT:

I got this line from the log file:

runsystem(cmd.exe)...disabled (restricted).

\documentclass{report}
\immediate\write18{cmd.exe}
\begin{document}
...
\end{document}

Run pdflatex (or other engine) with the -shell-escape option. — egreg, May 23 '16 at 19:49
@egreg i already tried -shell-escape same as with --enable-write18 i believe it's double hyphen -- pdflatex -synctex=1 -interaction=nonstopmode --shell-escape %.tex, shell didnt run. @Bernard TexMaker — Cfun, May 23 '16 at 20:01
Did you configure TeXmaker to use the --enable-write18 switch for pdflatex? — Bernard, May 23 '16 at 20:20
For me it works fine with auto-pst-pdf and pstricks files. Could you post a minimal (non-)working example? — Bernard, May 23 '16 at 20:35
@Bernard done. i dont see any instance of command line launched during/after compilation. — Cfun, May 23 '16 at 20:46

I don't think that cmd.exe was ever directly allowed (in restricted mode). You need to run your document with --shell-escape.

When I try your document I get a prompt in the window where pdflatex compiled the document.

If you want a new cmd.exe windows you should probably use

\immediate\write18{start cmd.exe}

(again --shell-escape is needed).
