Adding or Removing a Software Package (pkgadd)
All the software management tools that are listed in Table 18-1 are used
to add, remove, or query information about installed software. The Solaris Product Registry prodreg
viewer and the Solaris installation GUI both access install data that is
stored in the Solaris Product Registry. The package tools, such as the
pkgadd and pkgrm commands, also access or modify install data.
When you add a package, the pkgadd command uncompresses and copies files from
the installation media to a local system's disk. When you remove a package,
the pkgrm command deletes all files associated with that package, unless those files
are also shared with other packages.
Package files are delivered in package format and are unusable as they are
delivered. The pkgadd command interprets the software package's control files, and then uncompresses
and installs the product files onto the system's local disk.
Although the pkgadd and pkgrm commands do not log their output to a
standard location, they do keep track of the package that is installed or
removed. The pkgadd and pkgrm commands store information about a package that
has been installed or removed in a software product database.
By updating this database, the pkgadd and pkgrm commands keep a record
of all software products installed on the system.
