[Bash] New line character in variable

Hi,

How can I include a new line character in a variable in a bash shell script?

test.sh
=============
myvar="line1\nline2"
echo $myvar # gives line1\nline2

Doesn't work...and I have already tried many different combinations (\r\n, etc etc).

Thanks in advance.

Michael

Hi,

Use echo -e instead of echo.

Code:

#!/bin/bash

myvar="line1\nline2"

echo -e $myvar

man bash for details.

Hope this helps.

druuna is right.

Code:

man echo

-e makes echo interpret some backslash escape sequences like \n, \r, \t, etc.

No need for the echo command, myvar=$'\n' will also do the trick.
