With GNU sed 4.x, this is no longer the case :)

grep -rl mypassword * | sed -i~ -e s/mypassword/dummypassword/g

would edit the files in-place and back the old ones up to files with a
tilde suffix.

Now sed has edit-in-place and shell invocation, grep has a plugin
architecture and you can write network servers in awk... who needs perl?
