It just occurs to me that you said the file holds the names in upper cases (my previous post assumed lower-case).

So use this instead:

perl -i.old -pe 's/(?<=[A-Z])(\w)/lc $1/eg' <FILENAME>

And the regex contains a (this time positive) lookbehind-assertion (and not lookahead as I wrote above).

Sorry for the confusion.
