Question

Why is it when I run this command in powershell:

 $output = (svn stat) -match '^\?' # which $output is an [object] in this case.

I get this output in the PowerGUI Script Editor Console when viewing the variable $output:

?       Projects\TestProject\Thisisatest.txt
?       Projects\TestProject\Thisisatest - Copy.txt

but when I run this command:

[string] $output = (svn stat) -match '^\?'

I get these results:

?       Projects\TestProject\Thisisatest.txt ?       Projects\TestProject\Thisisatest - Copy.txt

It seems when using [string] it does some type of encoding where it takes away newlines and I’m not sure why?

UPDATED
user978511 here is the the small example code and output

Clear-Host
Set-Location "C:\svn\Development\Projects\TestProjects\build"
$output = (svn stat) -match '^\?'
'$output results'
$output

'$output2 results'
[string] $output2 = (svn stat) -match '^\?'
$output2

Output:

$output results
?       Projects\TestProject\Thisisatest.txt
?       Projects\TestProject\Thisisatest - Copy.txt
$output2 results
?       Projects\TestProject\Thisisatest.txt ?       Projects\TestProject\Thisisatest - Copy.txt

Thanks for anyone that can help.

When PowerShell casts an array to a single string it converts the members to strings and concatenates them with spaces between each.

$output2 = [string]::join([environment]::newline, $output) will do what you want.
