PowerShell Here-String that keeps newlines

The PowerShell code:

$string = @'
Line 1

Line 3
'@
$string

Outputs:

Line 1
Line 3

But I want it to output:

Line 1

Line 3

How can I achieve that?

Here is another way, especially if you don't want to alter the here-string itself. This quick solution works great for me as it reinstates the expected behaviour of New-Line character (CRLF) stored within a Here-String / Verbatim-String without having to alter the Here-string itself. What you can do is either:

$here_str = $here_str -split ([char]13+[char]10)

OR

$here_str = $here_str -split [Environment]::NewLine

To test, you can do a line-count:

($here_str).Count

Here is your example:

$string = @'
Line 1

Line 3
'@

#Line-Count *Before*:
$string.Count         #1

$string = $string -split [Environment]::NewLine

#Line-Count *After*:
$string.Count         #3

$string

Output:

Line 1

Line 3

another option is to use: "@+[environment]::NewLine+[environment]::NewLine+@" which may look ugly but works as needed. The upper example would then be:

$string = @"
Line 1
"@+[environment]::NewLine+[environment]::NewLine+@"
Line 3
"@

In ISE works fine and in script works too. I don't remember where, but I read that is a bug in the console host code and empty lines are discarded when entered interactively for here-string. At the moment I can't test if in Powershell V.3.0 console bug is fixed.

Link to the issue: http://connect.microsoft.com/PowerShell/feedback/details/571644/a-here-string-cannot-contain-blank-line

Workaround: add a backticks `

$string = @"
Line 1
`
Line 3
"@
