Guidelines for Removing Packages

You should use one of these tools to remove a package, even though you might be tempted to use the rm command instead. For example, you could use the rm command to remove a binary executable file, but that is not the same as using the pkgrm command to remove the software package that includes that binary executable. Using the rm command to remove a package's files will corrupt the software products database. (If you really only want to remove one file, you can use the removef command, which will update the software product database correctly. For more information, see removef(1M).)

If you intend to keep multiple versions of a package (for example, multiple versions of a document processing application), install new versions into a different directory than the already installed package with the pkgadd command. The directory where a package is installed is referred to as the base directory. You can manipulate the base directory by setting the basedir keyword in a special file called an administration file. For more information on using an administration file and on setting the base directory, see Avoiding User Interaction When Adding Packages and admin(4).

If you use the upgrade option when installing the Solaris software, the Solaris installation software consults the software product database to determine the products that are already installed on the system.
