addendum:

I have more problems and other problems too.

test:

echo -e "a\n\nb" | sed 's/\n//g'

does not handle \n for newline.

I have to make more investgations.
Excuse me.

test:

echo -e "a\n\nb" | tr -s '\n'

or

echo -e "a\n\nb" | tr -s '\n' '\n'

both empty lines are removed, not only one.

Please: is there a wayaround known?
