Anonymous Monk has asked for the wisdom of the Perl Monks concerning the following question:

Hi. I'm running Perl 5.8.2 under Windows. I'm calling the "psftp" command from Perl using the backquotes to collect the command output in a variable to keep the output from going to a command prompt screen. The following line of code I'm using puts most of the output into the variable: $output = `psftp $user -pw $server -b $ftpCommands`; However, the text: Using username "ftpuser". is still displayed on the screen. Does anyone have any suggestions as to why that particular message isn't redirected to the variable?

    Please read Writeup Formatting Tips. In particular, using <code> tags to surround code, though it is less important in this case.

    I suspect the displayed text is being output to STDERR and not STDOUT. You should be able to redirect it to STDOUT with 2>&1, so your entire command becomes

    $output = `psftp $user -pw $server -b $ftpCommands 2>&1`;

      Yeah, using 2>&1 worked perfectly. Thank you!! Sorry about not using the <code> tags. Thanks again.
