Use Variables created in script block outside of script block

Question

hello
I have a code like:
$command= { param($p1,$p2) if (Test-Path "D:\$p1") {
$s=$p1+ "_" +$p2 } }
Invoke-Command -session $sesion -ScriptBlock $command -ArgumentList 1,2here session is already created with remote server. Invoke-Command runs that script block on a remote server.Now I want to use that variable $s after invoke-command like $command= { param($p1,$p2) if (Test-Path "D:\$p1") { $s=$p1+ "_" +$p2 } }
Invoke-Command -session $sesion -ScriptBlock $command -ArgumentList 1,2write-host $sif ($s -eq "ZTE_3G") {Write-host True} else {write host false}But here value of variable $s comes as null.Could you please help me how can i use value of that vairable?

Answer 1

You need to return $s in your scriptblock and then save the output of Invoke-Command to a variable in order to test.
Something like this may work:
$command= {
param($p1,$p2)
if (Test-Path "D:\$p1") {
$s=$p1+ "_" +$p2
$s
$s = Invoke-Command -session $sesion -ScriptBlock $command -ArgumentList 1,2
write-host $s
If ($s -eq "ZTE_3G") {
$True
} else {
$False
