This is perfect. Thanks again. SmilieSmilieSmilieSmilie

Quick question, how to stop this loop besides using combination of Ctrl + C?

Code:
type8code0@box:~/dbedit$ ./test
Enter new group name : XYZ
You entered: XYZ
create service_group XYZ
create service_group XYZ '' services:tcp22
create service_group XYZ '' services:tcp80
create service_group XYZ '' services:tcp443
Enter new group name :
You entered:
create service_group
create service_group  '' services:tcp22
create service_group  '' services:tcp80
create service_group  '' services:tcp443
Enter new group name : ABC
You entered: ABC
create service_group ABC
create service_group ABC '' services:tcp22
create service_group ABC '' services:tcp80
create service_group ABC '' services:tcp443
Enter new group name :
