Answer

The ability of interacting with nested project is added into tabcmd starting from versions 10.5.8 and 2018.1.4. You can access nested projects by the --parent-project-path parameter with the functions for createproject, publish, publishsamples, refreshextracts, delete, and deleteproject.

--parent-project-path takes an argument of the path of the parent projects with a '/' separating nested projects like:

tabcmd -publish "C:\tableau files\filename.twbx" -r childTier2 --parent-project-path parent/childTier1

The command above will publish the file to the parent/childTier1/childTier2 project.
