[Textures] \write18

[Emilio Faro]

The following LaTeX code:
%------------------------------
\documentclass{article}
\begin{document}
\immediate\write18{echo `pwd` > pwd.txt}
\end{document}
%------------------------------
gives me the expected thing (a text file named "pwd.txt" containing the path to the parent folder of the file being compiled) if I compile it with TeXShop, but not with Textures. It seems that \write18 is not enabled in Textures. Does anybody know how to enable it?
Thank you.
