TiTle: How to collect output of DB2 query run interactive mode using perl script

I need to write a perl script which will run the DB2 query (describe "select * from ") in interactive mode and collect the output of it to get the colname, typename and length from it. Here is what I have tried so far. My main goal is to collect the colname, typename and length from the query 'describe "select * from indic.name"'. Kindly let me know if any other efficient alternative way is there. I can not use DBI module as it was not installed. 

use strict;
use warnings;

my @cmd_list = ( 'db2', 'connect to ctinld01 user db2tf0 using db2tf0'
+, 'describe select * from indic.name');

$|++;  # turn off buffering

my $shpid = open( my $sh, '|-', '/bin/bash' )
    or die "Can't open a shell process: $!\n";

for my $cmd ( @cmd_list ) {
    if($cmd eq "describe select * from indic.name")
    {
        open (STDOUT, "| tee -ai logs.txt");
        print $sh "$cmd\n";
        print "It Works!";
        close STDOUT;
    }
    else
    {
        print $sh "$cmd\n";
    }
}
print $sh "exit\n";
close $sh;
waitpid( $shpid, 0 );

print "Shell's all done.  Moving right along...\n";
