What packages do I have installed in Fedora?

There’re easy things to do that I forget how to do it… For instance, I know that I may get a whole package list if I type: rpm -qa on my console screen. I know that I may get information about packages by typing
rpm -qi package_name
or by typing
yum info package_name

Since I’m experiencing some issues with my Eclipse installation I was comparing my version with recommended version from UOC, so I wanna know what software do I have installed that starts with eclipse* pattern… how can we do it? My old-fashioned way was to type
rpm -qa | grep eclipse
but there’s a more cool way, after a read a little bit from your manual page you may type something like
yum list installed eclipse*
So don’t forget to read man pages buddys.
