sh variants work as well. I think using basename is much more
readable than piping into perl and using perl to do the rename.

But in any ahem Unix system, you can already do, ad hoc:
$ ls | perl -n -e 'chomp; m/(.*)\.log$/ && rename($_,
"$1.old");'
Use 'find' to do it recursively, of course (try doing *that* in DOS).
Wow, that's so elegant. It only requires spawning two processes, piping
to a general purpose programming language, and using regexps to make it
work!
Wait, is elegant the word I want to use here? Hmm.
