Try this Module. I think its exaclty what you want: Config::IniFiles

use Config::IniFiles;
$cfg = Config::IniFiles->new( -file => "Sample.ini" );
$value = $cfg->val( 'Section1', 'workers' );
$value = $value + 5;
$cfg->setval( "agent", "numworkers", $value );
$cfg->WriteConfig( 'agent.ini', -delta => 1 );

Thanks you Code works: use Config::IniFiles; $cfg=Config::IniFiles->new(-file=>"Sample.ini"); $value=$cfg->val('Section1','workers'); $value=$value+5; $cfg->setval("agent","numworkers",$value); $cfg->WriteConfig('agent.ini', -delta=>1);
