Line separator in command line

How do I send an email, where "Hello world!" appears in the first line and "Test run" appears in the second line. I have tried \r\n and \n. Are there any way to stack the line after line?

echo "Hello world! \r\n Test run" | mail -s "Test" [email protected]

The email should be viewed like:

Hello world!

Test run

If you want more than two or three lines, you can also use the following syntax:

mail -s "Test" [email protected] << EOF

then type your mail and finally a line with only EOF in it; it will allow you to type text on several lines as a single "logical" command line. (Try to browse the history of your command line after that, you will understand what I mean by "one logical command line".

Use echo -e. From the manual:

If the -e option is given, interpretation of the following backslash-escaped characters is enabled. [...]

# echo -e "Hello world! \r\n Test run"
Hello world!
 Test run

In bash you can also use $'string':

Words of the form $'string' are treated specially. The word expands to string, with backslash-escaped characters replaced as specified by the ANSI C standard.

# echo $'Hello world! \r\n Test run'
Hello world!
 Test run
