I am trying to use a loop to strip of the funny character ^M at the end of all lines in each file found in current directory and I have used the following in a script:

find . -type f -name '*.txt' | while read file
do
echo "stripping ^M from [$file]..."
ex - "$file" > $tempfile
%s/^M//g
wq!
# mv -i "$tempfile" > "$file"
done;

I got the following error messages instead:

0602-004 The specified address is not valid.
ex: 0602-004 The specified address is not valid.
teststrip[11]: %s/^M//g: not found.
teststrip[12]: wq!: not found.

Can anyone help please?

Appreciate much!

What is your OS ?

uname -a

Aix 5.3

OK, try sed instead:

 find . -type f -name '*.txt' | 
	while read file
	 do
           sed 's/^M$//' "$file" > "$file".tmp && mv "$file".tmp "$file"
         done

Try this..

 
find . -type f -name '*.txt' | while read file
do
echo "stripping ^M from [$file]..."
sed "s/^M//g" file > temp_file
mv -f temp_file > file
done
