Thank you for your response.

I will try it with IPC::Open3.

I'm trying to create a simple example for IPC::Open3. Should I create a separate post relating to getting Open3 to work?

Below is code I am trying and here is the output I get:

OUTPUT: 
err-> /bin/ls: write error: Bad file descriptor retval-> 512

CODE: 
#!/usr/bin/perl
use warnings;
use strict;
use IPC::Open3;

print "Content-type: text/html\n\n";

print ' <!DOCTYPE HTML>
        <html lang="en">
        <head>
          <title>IPC::Open3 Example</title>
        </head>
        <body>';

        
my $cmd = '/bin/ls -la';

my $pid = open3(\*WRITER, \*READER, \*ERROR, $cmd);

while( my $output = <READER> ) {
  print "output-> $output\n";
}

while(my $errout = <ERROR> ) {
  print "err-> $errout\n";
}

waitpid($pid, 0 ) or die "$!\n";
my $retval =  $?;
print "retval-> $retval\n";

print " </body>
        </html>";
