Validates a comment block for a script.


    [-Path] <String>
    -LiteralPath <String>


The Test-ScriptFileInfo cmdlet validates the comment block at the beginning of a script that will be published with the Publish-Script cmdlet. If the comment block has an error, this cmdlet returns information about where the error is located or how to correct it.


Example 1: Test a script file

Test-ScriptFileInfo -Path "C:\temp\temp_scripts\New-ScriptFile.ps1"

This command tests the New-ScriptFile.ps1 script file and displays the results. The script file includes valid metadata.

Example 2: Test a script file that has values for all metadata properties

Test-ScriptFileInfo -Path "D:\code\Test-Runbook.ps1" | Format-List *

Name                       : Test-Runbook
Path                       : D:\code\Test-Runbook.ps1

ExportedWorkflows          : My-Workflow

This command tests the script file Test-Runbook.ps1 and uses the pipeline operator to pass the results to the Format-List cmdlet to format the results.

Example 3: Test a script file that has no metadata

Test-ScriptFileInfo -Path "D:\code\Hello-World.ps1"

Test-ScriptFileInfo : Script 'D:\code\Hello-World.ps1' is missing required metadata properties. Verify that the script file has Version, Description
and Author properties. You can use the Update-ScriptFileInfo or New-ScriptFileInfo cmdlet to add or update the PSScriptInfo to the script file.
At line:1 char:1
+ Test-ScriptFileInfo D:\code\Hello-World.ps1
+ ~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
+ CategoryInfo          : InvalidArgument: (D:\code\Hello-World.ps1:String) [Test-ScriptFileInfo], ArgumentException

+ FullyQualifiedErrorId : MissingRequiredPSScriptInfoProperties,Test-ScriptFile

This command tests the script file Hello-World.ps1, which has no metadata associated with it.



Specifies a path to one or more locations. Unlike the Path parameter, the value of the LiteralPath parameter is used exactly as it is entered. No characters are interpreted as wildcards. If the path includes escape characters, enclose them in single quotation marks. Single quotation marks tell PowerShell not to interpret any characters as escape sequences.
