This simple loop should do the job,checked in bash/zsh.
for filename in $(find . -type f);do
	if [[ -n $(file $filename |grep CRLF) ]]
	sed 's/^M$//' $filename > $filename.unix

You can use the dos2unix command instead of sed,if you like,
but I don't know it's syntax.
There should be a choice for a backup I guess.

If you decide to use the sed,you can type the ^M in your shell,or in
your editor with
or with 

If you have checked your files and you are satisfied,then you 
can rename them in it's previous original name.

for filename in $(find . -type f -name "*unix");do
	mv -v $filename ${filename%.unix}
