I'm using open3 method to run a dos command 'DIR', it stops here:
open3($rdr, \*POut, \*PErr, $cmd);
Any one knows what's the problem? Thanks very much!
#!/usr/bin/perl -w
use strict;
use File::Find;
use File::Copy;
use Time::Local;
use IPC::Open3;
my $log="TestOpen3.log";
open FHO, ">$log";
select FHO;
&executeCmd("dir * \/b\/s");
close FHO;
exit;
sub executeCmd{
my ($cmd) = @_;
print "Execute Command: $cmd\n";
use Symbol 'gensym';
my $rdr = gensym;
my $pid = open3($rdr, \*POut, \*PErr, $cmd);
waitpid( $pid, 0 );
if((my $returnCode = $? >> 8) !=0){
print "[ERROR] ($returnCode) : ";
while(<PErr>)
{
print;
}
close PErr;
die $returnCode;
}
while(<POut>)
{
print "\t".$_;
}
close POut;
}

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).
