I just use the following script (which I call jtom):

#!/usr/bin/sh

pid=$$
trap "rm /tmp/jtom.$pid 2> /dev/null ; mv /tmp/jtom.$pid.2 $1 2> /dev/null; \
     exit" 15 2 1

while test $# -gt 0
do
/usr/bin/echo -n $1
/usr/bin/echo -n ' ... '
     cp $1 /tmp/jtom.$pid.2
     cat $1 | tr \\012 \\015 > /tmp/jtom.$pid
     mv /tmp/jtom.$pid $1
     rm /tmp/jtom.$pid.2
     shift
/usr/bin/echo 'done'
done


To convert ^M's to ^J's, just switch the \\012 and \\015.
