If you want the information about the column , like its type etc., don't do it by running an external program, but do it by using the catalog methods. What you want is basically:

use DBI;
my $dbh = DBI->connect('dbi:DB2', 'db2tf0' );
my $sth_columns = $dbh->column_info(undef, undef, 'indic.name', undef)
+;
# print out the results

If you really cannot use DBI and your system administrator won't install it, maybe you can simply pipe text into the db2 shell instead of trying to run things interactively:

my @results = qx(echo 'connect to ctinld01 user db2tf0 using db2tf0\nd
+escribe select * from indic.name' | db2 );
print "<$_>" for @results;

According to the db2 manual, you can simply pass the SQL statement(s) to the db2 tool:

db2 "connect ..." "select ..."
