rpmbuild

Sometimes the simplest things will slip by you for the longest time.

After time after time of trying to find a definitive list of macros available for use in RPM specfiles on the Internet, I finally read the rpmbuild man page just to find the '--showrc' option. From the docs:

The command rpmbuild --showrc shows the values rpmbuild will use for all of the options are currently set in rpmrc and macros configuration file(s).

Now I can easily run rpmbuild --showrc and grep the output for whatever I'm looking for.

Doy! :-p
