Hello Sir/Madam,
I am stuck with the second of two examples on Page 96 (Chapter 8 - Objects)of this book Learn Windows Powershell in a Month of Lunches (3rd ed.). The second command, which is:
Get-Process | Select-Object -property Name,ID,PD,VM | Convert-ToHTML | Out-File test2.html
generates an error message that says: “Convert-ToHTML is not recognized as the name of a cmdlet, function …”.
After several “closer examinations” of the example, I realized that it mis-spells “Convert-ToHTML”: the correct syntax should be “ConvertTo-HTML”. I have changed this post after discovering the reason for the error.
Sincerely,
Ramon Tan
It’s because this…
Convert-ToHTML
… is not a cmdlet in PoSH. It’s a typo.
Get-Command -Name *html*
CommandType Name Version Source
----------- ---- ------- ------
Cmdlet ConvertTo-Html 3.1.0.0 Microsoft.PowerShell.Utility
...
When you run into messages the say X or Y is not valid, always look it up in the built-in help files.
Here is a snippet I pulled together for such efforts. Just save it as a snippet in you PoSH snippets so you can bring it up as needed when looking up stuff.
