I am facing a peculiar issue in PowerShell 2.0. I am not an expert in PS, but occasionally write/edit few scripts to work with Nagios monitoring tool. Requesting help form Nagios experts. Your help will be appreciated.

The script ExServiceAlert10.ps1 is embedded below:

#First, findout if Exchange Management Shell is loaded:
$snapins = Get-PSSnapin |select name
$snapincount=0;
$found = $false
do

$founDName = $snapins[$snapincount].name
if ($founDName -eq “Microsoft.Exchange.Management.PowerShell.E2010″)
#Exchange Shell already loaded

$found = $True
break

$snapincount++
while ($snapincount -lt $snapins.Count)
if ($found -ne $True)

Add-PSSnapin Microsoft.Exchange.Management.PowerShell.E2010

# Create variables
$status = 0
$desc = “”
# Get Service Health
Test-ServiceHealth | ForEach-Object 
$main = “`n" + "Role: " + $_.Role + "`n” + “Status: ” + $_.RequiredServicesRunning + “`n”
if ($_.RequiredServicesRunning -eq “True”)
$array = $_.ServicesRunning
$runningsvcs = “Services running:”
foreach ($svc in $array)
$runningsvcs = $runningsvcs + ” ” + $svc

$desc += $main +$runningsvcs + “`n”
else
$status = 1
$array = $_.ServicesNotRunning
$notrunning = “Services Not running”
foreach ($svc in $array)
$notrunning = $notrunning + ” ” + $svc

$desc += $main + $notrunning


if ($status -eq 1)
echo “Critical – Exchange Services Alert $desc”
exit 2
else
echo “OK – Exchange Services Alert $desc”
exit 0

The script is working fine and shows no error, if I directly execute it in PowerShell like this:

PS C:Windowssystem32> D:ExServiceAlert10.ps1

But it shows error when I execute it via cmd or from Nagios NSClient++ like this:

Normal command Prompt execution: (Script placed at D:)
D:>echo .ExServiceAlert10.ps1 ; exit $LastExitCode | powershell.exe -command -

From nagios NSclient++ execution via check_nrpe: (Script placed at NSclient Script directory)

cmd /c echo scriptsExServiceAlert10.ps1; exit $LastExitCode | powershell.exe -command –

The error I am getting is this:

Missing expression after unary opearator ‘-’.

At line:1 char:2
+ – <<<<
+ CategoryInfo : ParseError: (-:String) , ParentContainsErrorRecordException
+FullyQualifiedErrorId : MissingExpressionAfterOperator

I am executing this script in PowerShell 2.0 and tried various debugging methods to solve this for the past week with no success.

Here are some entries from my NSClient++ conf. file NSC.ini for other PS scripts which are working fine without any issue.

exch_mail_flow10=cmd /c echo scriptsExchMailFlow10.ps1; exit $LastExitCode | powershell.exe -command -
exch_mailboxhealth10=cmd /c echo scriptsExMailboxhealth10.ps1; exit $LastExitCode | powershell.exe -command –

Even the reported errant script(ExServiceAlert10.ps1) is working fine in my test system with that extra dash in command prompt but not working at all in any of the the Prod. system. All the PS versions are 2.0.

I think either I have to enable/disable some PS environment settings on those errant Prod. systems, or to escape something inside the script (suspecting newline characters- `n backtick n) . I don’t understand why it is reporting Line:1 and char:2, which is nothing but a comment line in the script.

I have seen this particular error reported by few others and their issue was resolved after upgrading their PS to Ver 2.0. Mine is already 2.0 and don’t know what to do next.

At the end I am able to crack the issue and it was very difficult to find. Our administartor copied/pasted the command line for NSC.ini file from a MS-Word document (How To doc.) shared by me to them. In the original MS-Word doc the hypen (at the end of the line after the word command in the beow given command line) has automatically changed to a little bigger hypen during documentation, which also gone to the NSC.ini file and hence the error was coming for this particular command execution. After changing the hypen manually in the NSC.ini, it worked fine without any issues
