I am tired of having to re-write, manually, all the *.rpmnew files that appear when I upgrade. Most of them don't need to be diff'ed, in my case at least.

For example, I just diff the httpd.conf file and that's it so, here's a script to mv *.rpmnew to *:

find . -iname '*.rpmnew' | while read f; do mv -f $f ${f%.rpmnew}; done
