How to compose a multi-line query in the terminal?

Question

linux

Good afternoon.
In the terminal I execute the Mediawiki script command (text replacement)

php replaceAll.php "Заменяемый текст" "Текст на замену"

My replacement text consists of strings, for example,

строка1
Строка2

I need to replace "Line1+paragraph mark" with:

Строка3
Строка4

Those. should get:

Строка3
Строка4
Строка2

The problem is how to write paragraph marks in the query in the console?

Answer 1

cd ~ && \
> echo "hello"

Answer 2
