How to find files with ^M from linux using csh

Question

Is there a csh script/command to list all the files in source source tree which have line endings that show up as "^M" in emacs (under linux).

Thanks!

Answer 1

Based on my answer to another question:

fgrep -rl `echo -ne '\r'` .

Answer 2

find . -type f -exec grep $'\r' {} +

The $'\r' probably requires bash to function correctly.

Answer 3

find . -type f -print | xargs grep 'cntl-M$'

where cntl-M has been entered by first entering cntl-V
