 Examples
    
EXAMPLE 1
 

    C:\PS>get-AuthenticodeSignature -filepath C:\Test\NewScript.ps1 

     Description
 
    ----------- 
    This command gets information about the Authenticode signature in the NewScript.ps1 file. It uses the FilePath parameter to specify the file. 

    
EXAMPLE 2
 

    C:\PS>get-authenticodesignature test.ps1, test1.ps1, sign-file.ps1, makexml.ps1 

     Description
 
    ----------- 
    This command gets information about the Authenticode signature in the four files listed at the command line. In this command, the name of the FilePath parameter, which is optional, is omitted. 

    
EXAMPLE 3
 

    C:\PS>get-childitem $pshome\*.* | foreach-object {Get-AuthenticodeSignature $_} | where {$_.status -eq "Valid"} 

     Description
 
    ----------- 
    This command lists all of the files in the $pshome directory that have a valid Authenticode signature. The $pshome automatic variable contains the path to the Windows PowerShell installation directory. 

    The command uses the Get-ChildItem cmdlet to get the files in the $pshome directory. It uses a pattern of *.* to exclude directories (although it also excludes files without a dot in the filename). 

    The command uses a pipeline operator (|) to send the files in $pshome to the Foreach-Object cmdlet, where Get-AuthenticodeSignature is called for each file. 

    The results of the Get-AuthenticodeSignature command are sent to a Where-Object command that selects only the signature objects with a status of "Valid".
