[Sunhelp] How do I know which package to add?

[Irwin R. Naumann]

I looked in the Solaris FAQ and Solaris x86 FAQ but I can't find
an answer.

I installed the Solaris 2.6 CORE distribution on an x86 platform.

The "showrev" command is not found. I'd like to install this command.

The Solaris Advanced Installation Guide's Appendix A lists the packages and
gives a package description. Can I find out in which package a particular
command resides?

Is there an index which details what commands reside in what package?

Thanks,

   Irwin
