Hi,
I'm trying to get the stdout and stderr from a process executed from my perl script in the following way
use IO::CaptureOutput qw/capture/;
$cmd = "xcopy /Y /S /E /I /F /R /K $source $dest";
capture { system $cmd } \$stdout, \$stderr;
print "Output is : "."\n"."$stdout\n";
print "Error is : "."\n"."$stderr\n";
print "Exit code is : "."\n"."$?\n";
Problem is that this works fine exactly the way it is.
I'm trying it in a windows xp professional machine with ActivePerl.
But when I'm kicking off the command(xcopy, etc.) from a sub which is called from another sub,
which in turn is called from another sub, $stdout comes up as an empty string.
I'm echoing the values from the sub where the process is kicked off to get around issues related to scope of variables. I'm baffled by this. Does anybody know the answer to this weird behaviour. Will really appreciate it.

Posts may use any of the Perl Monks Approved HTML tags. Currently these include the following:
<code> <a> <b> <big>
<blockquote> <br /> <dd>
<dl> <dt> <em> <font>
<h1> <h2> <h3> <h4>
<h5> <h6> <hr /> <i>
<li> <nbsp> <ol> <p>
<small> <strike> <strong>
<sub> <sup> <table>
<td> <th> <tr> <tt>
<u> <ul>
-
Snippets of code should be wrapped in
<code> tags not
<pre> tags. In fact, <pre>
tags should generally be avoided. If they must
be used, extreme care should be
taken to ensure that their contents do not
have long lines (<70 chars), in order to prevent
horizontal scrolling (and possible janitor
intervention).
