removing control character from all files

I have directory structure containing many files. The directory
structure is of depth 10. I want to remove the control character from
all the files in the directory structure . If the control character is
^M please help me with the command to recursively visit the files in
the directory structure and replace the control character.


Thanks & regards,
Onkar

Follg gives the basic idea. Add error handling/exceptions as
required. Type the ^M as a sequence of Ctrl-V and Ctrl-M (in
vi editor). If you want to overwrite the files, first write the output
to a temp file and then copy over.

find . -type f | while read name
do
cat $name | sed -e 's/^M//g' > $name.clean
done

With GNU sed you can edit files in place:

sed -i -e 's/foo/bar/g' "$name"

You like complex thinks.

With GNU sed:

find . -type f -execdir sed -i 's/\r//g' {} \;

This avoids trouble if you have foo & foo.clean

To keep leading or trailing whitespace in filenames, set IFS, and
to keep backslashes, use the -r option:

find . -type f | while IFS= read -r name

You don't need cat, and the variables should be quoted in case
there are spaces in the filenames:

sed -e 's/^M//g' "$name" > "$name.clean"

If you are going to use the -i option, also give a suffix so that
a backup will be made:

sed -i.bak -e 's/foo/bar/g' "$name"

FreeBSD sed also has the -i option, and the suffix is mandatory,
