Answer 1

$ServerList = Get-Content -Path "c:\users\cont015\Desktop\ServerList.txt"
ForEach ($ServerName in $ServerList)
{
$Status= #(
Get-Service -ComputerName $ServerName -DisplayName "SQL Server (*" |
Select-Object -ExpandProperty Status)
if ("Running" -in $Status)
{
[PSCustomObject]#{
Server = $ServerName
Status = $Status
}
}
else
{
}
}
Explanation:
Get-Service docs: -DisplayName
Specifies, as a string array, the display names of services to be retrieved. Wildcards are permitted (used instead of Where-Object as such filtering is always faster).
Array subexpression operator #( ). -
Returns the result of one or more statements as an array. The result is always an array of 0 or more objects (i.e. force Powershell to always return an array when a call returns only one object or even $null)
Used [PSCustomObject]#{} in output instead of a sequence of strings (learn advantages at Everything you wanted to know about PSCustomObject).
