Hi, I'm trying to run a command on a unix box using system because I need the exit code. but I also need the stdout and stderr. so I try some STDOUT redirection unfortunatelly it works if I redirect to a file:

open(STDOUT, '>' ,"kk.txt" ) or die "Can't redirect stdout: $!";

But not when I do it to a variable:

open(STDOUT, '>' ,\$output ) or die "Can't redirect stdout: $!";

This is my Testing code:

#!/usr/bin/perl
my $exitcode ;
my $output='';
my $error='';
# take copies of the file descriptors
open(OLDOUT, ">&STDOUT");
open(OLDERR, ">&STDERR");
#close current outs as per manual of open
close(STDOUT)                       or die "Can't close STDOUT: $!";
close(STDERR)                       or die "Can't close STDERR: $!";

# redirect stdout and stderr
open(STDOUT, '>' ,\$output )  or die "Can't redirect stdout: $!";
#open(STDOUT, '>' ,"kk.txt" )  or die "Can't redirect stdout: $!";
open(STDERR, '>' ,\$error )            or die "Can't redirect stderr: 
+$!";

printf "Before system\n";

# run the program
system("echo I cant get this into a variable");
$exitcode=($? >>8);
printf "After System\n";

# close the redirected filehandles
close(STDOUT)                       or die "Can't close STDOUT: $!";
close(STDERR)                       or die "Can't close STDERR: $!";

# restore stdout and stderr
open(STDOUT, ">&OLDOUT")            or die "Can't restore stdout: $!";
open(STDERR, ">&OLDERR")            or die "Can't restore stderr: $!";

# avoid leaks by closing the independent copies
close(OLDOUT)                       or die "Can't close OLDOUT: $!";
close(OLDERR)                       or die "Can't close OLDERR: $!";

printf "Exitcode: %d\n" ,($exitcode);
printf "still here\n";
print $output ;
print $error ;

Please any help on why it does not work the redirection when is a variable?

Also if posible. how can I do this without system. remember I need exitcode stdout and stderr and I do not want to do any alter to the actual command to do unix redirections.

Many many thanks.
