Powershell command is not working

Hi Guys,


I am just trying to add a library template through powershell and it is not working. Any idea where thing might be going wrong.


here is the code snippet.


$sourceFile = "C:\mystuff\Library.stp"
$templateName = "Library.stp"

AddListTemplate -siteUrl "mysite.com/.../testsite" -fileServerFileName $sourceFile -listTemplateFileName $templateName

The term 'AddListTemplate' is not recognized as the name of a cmdlet, function,
 script file, or operable program. Check the spelling of the name, or if a path
 was included, verify that the path is correct and try again.
At line:1 char:16
+ AddListTemplate <<<<  -siteUrl "mysite.com/.../testsite" -fileServerFileName $sourceFile -listTemplateFileName $templateName
    + CategoryInfo          : ObjectNotFound: (AddListTemplate:String) [], Com
    + FullyQualifiedErrorId : CommandNotFoundException


Any help would be greatly appreciated.


Many Thanks in advance.
