Since Tableau released Tableau on Linux, we don't need to spend any more time on converting Windows Tabcmd for Linux. We can simply download tabcmd from Tableau website and install it to the Linux box with Matillion ETL. We are going to use 2018.2 version for this recipe but you can use 2019.x tabcmd distributive.
It is important that the tabcmd version was aligned with Tableau Server version. For example, if you have Tableau Server 2019.1 then you need to download Tabcmd 2019.1.
