Replicating Permissions with dbatools

Claudio Silva shows how you can take one user’s permission set and apply it to another user with dbatools:

What are the steps involved in a process like this?

Generally speaking, the quickest way I know is:
1. Get the permissions of the source login/user (For each database because we don’t want to miss any permission)
2. Save them to a .sql file
3. Open the file and replace ‘srcUser’ by ‘newUser’
4. Execute

Claudio shows how you can accomplish this quickly.
