Why not do something like:
for file in `ls thedirectorythefilesarein`
do
`sed -e s/\^M/\^J/ < $file > tmpfile` ;
mv $tmpfile $file
done
or instead of using ls, use find:
for file in `find /thedirectorythefilesarein -name ./* -print`
do
etc...
These methods would list each of the files in the directory and run them
through sed, changing your ^M's to ^J's. If the directory the files are
in has subdirectories, you would probably want to add in a test to make
sure the file is in fact a normal file and not a directory or some other
type of file. Something like: if [ -f $file ] then...
A word of caution. You will have to experiment with this a little bit to
get it to work. I am pretty much a beginner with shell scriptign myself,
and so I can not warrant this will work for you first time out. But, it
should get you started at least. I strongly recommend reading the man
pages for find, ls and test (there are at least two of these; one is a
bash built-in, the other a utility).
