DVT PSS IDE User Guide
Rev. 21.1.50, 23 November 2021
Presuming that you use ssh or telnet to connect to the unix environment you can use a putty tool to do this. The name of the command is plink.exe and it can be considered the analog of ssh for Windows.
You can use the plink.exe command with the DVT Generic Launch Configuration in DVT.
More information about how to use plink.exe can be found here http://the.earth.li/~sgtatham/putty/0.61/htmldoc/Chapter7.html#plink. There is also a sub chapter about how to use plink unattended (it won't require any interaction like user or password input).
