Ruby(1.9+)

$ ruby -e 'Dir["**/*.a"].each{|x|File.file?x && File.rename(x,"#{x}.b")}'

In a shell script (at least Bash 4)

shopt -s globstar
shopt -s nullglob
for file in **/*.a
do
 echo mv "${file}" "${file}.b"
done

find . -type f -name '*.a' -print0 | xargs -0 -IZZ mv ZZ ZZ.b

This should handle filenames with spaces and / or newlines. It also doesn't rename directories (the other solution doing find would). If you want it to be case-insensitive, use "-iname" instead of "-name"

Try the script below: 

for file in `find . -name '*.a'`; do mv $file $file.b; done

To rename <files> with that, rename 's/\.a$/.a.b/' <files>. Doing so recursively will just take a bit of looping.

(or use *, */*, */*/*, */*/*/*, etc. for the files)
