As far as I am aware this connot be done using Tabcmd
However, if you do need to do this without using the GUI, then you can use the REST API functionality.
Hope this helps
Hi Glen, thank for your quick reply.
I thought of doing this differently.
I have updated the record of 'project name' in pgsql and restarted the tableau.
This approach solve my problem.
I will try your solution as well.
