Thanks Troy! That's a nice tip, and much cleaner than
what I was previously doing (intermediary scripts).
Implementation was a little trickier than it first looked,
especially when you have variable input, due to the way
CMD treats the /C switch (details are in CMD /?)
One approach is to use the /S switch and always place
quotes at the beginning and ending of a command line,
which get stripped, but leave any other quotes intact.
Here's a convoluted example:
<target name="execute" depends="init-windows,init-linux">
<exec program="${shell}">
<arg line='${start}"${program}" ${params} < "${input}"${end}'/>
</exec>
</target>
<target name="init-windows" if="${platform::is-win32()}">
<property name="shell" value="CMD"/>
<property name="start" value='/S /C " '/>
<property name="end" value=' "'/>
</target>
<target name="init-linux" if="${platform::is-unix()}">
<property name="shell" value="sh"/>
<property name="start" value=""/>
<property name="end" value=""/>
</target>
Caveat: I haven't test this on Linux yet (waiting
for Mono on Linux to be more NAnt friendly) but it
worked on .Net and Mono on Windows
