  your function is in the powershell script, so the shell wont know about the function.

  you have to do a "dot sourcing"

  so you have to call it like this as mentioned in this url:

  Thanks Thiyagu for your Reply -:)....it worked that way....

  just a small question..i am doing remoting with powershell and passing variable to script block...

  function FindDuplicate($server,$config)

  {

  $configfile=$config

  $script=

  {

  Write-host $configfile  

  [xml]$e=GC $configfile | ?{$_ -ne""}

  }

   

   

  invoke-command -computername $servername -authentication CredSSP -Credential $cred -scriptblock $script -EA Stop;

   }

  Output: System.Management.Automation.RemoteException: Cannot bind argument to parameter 'Path' because it is null.
  Please let me know how i can use variable $configfile in Script block.

  Thanks

  Does this work?  I can't do any remote testing from where I am, and I question why that  | ?{$_ -ne"" is necessary.

  function FindDuplicate($server,$config)

  {

  $configfile=$config

  $script_str=@"
  Write-host $configfile 
  [xml]$e=GC $configfile | ?{$_ -ne""}
  "@

  $script = [scriptblock]::create($script_str)
   
  invoke-command -computername $servername -authentication CredSSP -Credential $cred -scriptblock $script -EA Stop;

   }

  Okay, I just realize why that might be necessary.  This will probably work better ( I think):

  function FindDuplicate($server,$config)

  {

  $configfile=$config

  $script_str= 'Write-host ' + $configfile +  ';[xml]$e=GC ' + $configfile + ' | ?{$_ -ne""}'

  $script = [scriptblock]::create($script_str)
   
  invoke-command -computername $servername -authentication CredSSP -Credential $cred -scriptblock $script -EA Stop;

   }

  Hi Mjolinor,

  I think i need to clarify a bit.

  I am reading the xml file that is on the remote machine and finding duplicate entires in that xml file.

  So i am passing the complete path of the xml file of the remote machine from the PS prompt.

  For Example:

  PS> Find-Duplicate server1 c:\Power\config.xml

  Now issue is occuring is in function:

  Function Find-Duplicate($server,$config)
  
  try
  
  {
  
  $servername=$server 
  
  $Configfile=$config
  
  
  Set-item WSMan:\localhost\shell\MaxMemoryPerShellMB 1000
  
  
  $Script=
  
  {
  
  [xml]$e=GC $configfile
  
  //When i try to use write-host just to see what is the value of variable $configfile in the $Script block , it is coming as Null. But above script block it's value is complete path of xml file what i give on Powershell prompt.
  
  //some logic 
  
  }
   invoke-command -computername $servername -authentication CredSSP -Credential $cred -scriptblock $script -EA Stop; 
  
   }
  
  Output: System.Management.Automation.RemoteException: Cannot bind argument to parameter 'Path' because it is null.
  
  
  
  

  Now question is how i can use the value of variable $configfile in Script block.

   Thanks

  Jaspreet
