IANAG ( I am not a guru ;-), however it would seem to me that the rm is
safe but that the unacceptable behaviour would be that all your files
would be renamed to *.old even if tr failed.
If the script did its juggling the other way around I would find it
acceptable.
for file in *; do
tr '\015' '\012' < $file > $file.new && mv $file.new $file
if [ -e $file.new ]; then
rm $file.new
fi
done
Warning *untested*
note: The "if" is not necessary if the translation goes according to
plan. It is only there to clean up if somethiing goes screwy.
tata for now
