Shell commands don't work on Windows

[bandel65]

e.g. "Echo Hello World{cmd=cmd.exe}" or "Echo Hello World{cmd=cmd.exe /c}"

Do you have any error message?

This works on Linux:

`echo Hello World`{cmd=sh}

If cmd needs more arguments, the whole command should be a quoted string otherwise Pandoc split words and the arguments won't be included in cmd:

`echo Hello World`{cmd="cmd /c"}

Christophe, thanks for getting back to me so quickly. ☺ No error message. It just hangs. If I try cmd=”sh” I get a panda lua system call error because there is no “sh” command on Windows (unless I install Cygwin ;-).

Did you try cmd="cmd /c" (with quotes around cmd /c)?

There may be another problem. cmd may expect specific file names (e.g. with the .bat extension). On Linux the filename does not matter. The script is saved to a temporary file which name may not be supported by cmd.

The doc says /e disables the extensions. And also /q to avoid unexpected outputs from cmd.

Maybe:

`echo Hello World`{cmd="cmd /e /q /c"}

or

`echo Hello World`{cmd="cmd /e:off /q /c"}

Had it in quotes, but hadn’t tried other options. I’ll look into that. Thanks.

None of that worked. Idiomatically, I don’t think Windows cmd.exe is capable of being invoked in this way, but I’m not certain.

I pushed a quick fix to add the file extension to the temporary script name according to the command. cmd.exe may accept to execute scripts with the .cmd extension. It seems to work on cmd.exe on Linux with Wine.
