Check Install History

Is there anyway to find the install history log on openSUSE 11.3 KDE4?

check out rpm in the man pages or type rpm --help in the console or terminal there is a way to list all rpm’s installed.

grep kde4 /var/log/zypp/history | less

…or if you just want to check the history of KDE4-versions:

grep libkde4 /var/log/zypp/history | less
