I need a command to find out if DNS is installed on ubuntu.

I installed and uninstalled bind9 on ubuntu.., I run the following command before and after bind9 installed, I got the same output:

dpkg -s bind9

apt-cache search bind9

I wonder what is the right command to find out if bind9 is installed or not.

Thanks

The command is dpkg.  The option is –get-selections.

You placed the space incorrectly in your command.
