This page confirms that the system's primary software
packages are properly installed and verifies that a complete version
of each application-specific package exists on the system. The system
takes a few minutes to perform a series of background checks on the
system software. The contents of each installed executable or help file,
but not data files, are checked to verify they were unchanged during
the lifetime of the system. Each of the primary software packages installed
on the system is listed. Exceptions are noted in the output of this
command.
