in reply to IPC::Open3 woes

I'm expecting this script to write the output from my test.pl script to output.log and errors from the test script to error.log, however both files are created, but empty.

Unfortunately, you can't just link one thing to another using a single filehandle. You'll have to create some data pipe yourself: read out the programs stdout and stderr, and write it back to the files you want. Don't forget to waitpid, after which $? will have the status code.

    This doesn't quite address the writer's original problem, though. He isn't expecting that, he's using the (correct) library module to set up the pipes on his behalf, behind the scenes. I think a large part of the problem stems from a lack of clarity in the manual page for IPC::Open3, at least in this case.
