Customization of PowerShell hash table merges(tellingmachine.com)

submitted by KlausKlaus(755) 3 years, 5 months ago

PowerShell provides the += operator to add one hash table to another hash table. By default this operation will result in an error, if both hash tables have at least one key that is common in both collections. In some cases you may want to have a more granular control. For example, you don't want to get an error, if not only the key, but also the value is common in both collections.
