That does not work in bash-4.x. Firstly, by default the bash builtin
'echo' supplies a trailing newline. Secondly, backslash translation
requires the option "-e".
$ echo "\n"
\n
$ echo "\n" | od -c
0000000 \ n \n
0000003
$
What does work is either of these:
$ echo '' | od -c
0000000 \n
0000001
$ echo -e -n '\n' | od -c
0000000 \n
0000001
$
