Currently, there’s no way to see the actual command line Patch My PC uses for an application installation from within the Intune portal. Confirming it, or checking whether a custom modified command line is in use, requires opening the Publisher.
It would be very helpful if the install (and ideally uninstall) command line was shown in Intune, such as in the application’s Notes field. This would make it much faster to verify and troubleshoot installations directly from the portal, especially when working from a machine without Publisher access.
