you definitely need to see find(1), sh(1), test(1).
in the meantime, if you are using ksh/sh/bash this should work w/
not much fiddling (partially tested in bash)...
find <directory> -type f |
while read Old
do
# this needs to be more sophisticated; but something is better than
# nothing
#
if ( ! file "$Old" | grep 'text' >/dev/null 2>&1 ) \
|| [ ! -f "$Old" -a -r "$Old" -a ! -L "$Old" ]
then
echo '* ' $Old 'may not be a text file or not readable; skipping...'
continue
fi
echo ' -- sanitizing ' $Old
tr -d '\r' < "$Old" > "${Old}.changed"
# optionally remove old files, keep only changed ones
#
#mv -f "${Old}.changed" "$Old"
done
