You should be able to figure this out pretty quickly on your own from
the manual, but I'll do your homework for you...

find . -type f -exec sed -i "" -e "s/e/E/g" {} \;

[changes every lower-case e to upper-case in all regular files in this
directory and all directories "below" it]

[There are several other ways to do it, too, in about the same amount
of typing.  In particular, using xargs(1) instead of -exec could make
it run faster if you have large numbers of files.]
