If the pkgadd command encounters a problem, it first checks the installation administration file for instructions. (See admin(4) for more information.) If no instructions exist, or if the relevant parameter in the administration file is set to ask, the pkgadd displays a message describing the problem and prompts for a reply. The prompt is usually Do you want to continue with this installation?. You should respond with yes, no, or quit.
If you have specified more than one package, no stops installation of the package being installed but pkgadd continues with installation of the other packages. quit indicates that pkgadd should stop installation of all packages.
