Hi all, sorry if this has already been asked but I wasn't able to find anything relevant by searching the forum...

I have a powershell script that uses the .NET assembly to manipulate some RHEL Linux servers. When sending a WGET command, the command exits cleanly but WinSCP reports an error. It doesn't matter what file I am downloading.

Exception calling "ExecuteCommand" with "1" argument(s): "Command 'wget http://intranet/'
failed with return code 0 and error message

Return code 0 indicates to me that all was successful. The files do in fact download as expected. I suspect wget is doing something silly like writing to StdErr as well as StdOut.

Is there any way to gracefully handle this exception and continue? Maybe some way to check what the error code was and ignore if it is 0?

Yes, it's error output that causes this. Just suppress it:
wget ... 2> /dev/null

Thanks, that seems to work. Hopefully it won't repress any actual failures.
