Hello,
I have been challenged to create a system analysis program, which collects data from a load of DOS (command line based) tools and dumps them into different files, which the Opus program runs in order, and another program then generates a report file from the results.

Now, in the old days of MS-DOS, if you put "> output.txt" on the end of a command, the command output would be rerouted to that file. It still works if you use the cmd.exe in Windows XP/Vista/7. I can therefore capture the data when I run the command from the command line, but as soon as I try the same from Opus it fails to work.

Here is a section of the Opuscript code I use to run the tool:

var Fname = SYSTEM_PUBLICATION_DIR + "tree.com"
var Params = "c:\ /f /a > " + SYSTEM_PUBLICATION_DIR + "\output\listc.txt"
LaunchFile(Fname,Params)

However, when it runs, no output is written to the file. I have tried different filenames, using the system built tree.com, but to no avail. However, as soon as I remove the redirection bit, it runs fine!

Any ideas?

Sorry if it seems unclear, just ask and i'll put more info up.

You'll need to run it through cmd.exe. So something like:

Hmm, tried that, and I get a command window up fine, but then the tree.com file runs, but the output still isn't redirected to the text file

Ben.

I missed out the /c



Is tree.com in your system publication dir? When I replaced that with just tree (built into Windows) it worked and I got the redirected output.

Also spaces in SYSTEM_PUBLICATION_DIR will make a mess of this.

Doesn't look like you can call cmd.exe within Windows 7 64-bit

Yes, it does.

Sorry, indeed it does open. It starts the 32-bit version of cmd.exe
