See Building a Package, if needed.
Log in to the system as superuser.
Add the software package to the system.
# pkgadd -d device-name [pkg-abbrev...]  | 
| 
 -d device-name  | 
 Specifies the location of the package. Note that device-name can be a full directory path name or the identifiers for a tape, floppy disk, or removable disk.  | 
| 
 pkg-abbrev  | 
 Is the name of one or more packages (separated by spaces) to be added. If omitted, pkgadd installs all available packages.  | 
To install a software package named pkgA from a tape device named /dev/rmt/0, you would enter the following command:
# pkgadd -d /dev/rmt/0 pkgA  | 
You can also install multiple packages at the same time, as long as you separate package names with a space, as follows:
# pkgadd -d /dev/rmt/0 pkgA pkgB pkgC  | 
If you do not name the device on which the package resides, the command checks the default spool directory (/var/spool/pkg). If the package is not there, the installation fails.
If you are ready to go to the next task, see How to Verify the Integrity of a Package.
