Command Line Tool

The command line is not a standalone tool. It only works in combination with a running Pipeline server. The server may be running on the same computer or a different one. See Configuration for how to specify the address of the server.


Choose a package from the downloads page that includes the command line tool, then follow the installation instructions for that package.


The executable is called dp2, or dp2.exe on Windows. Where exactly this file is located depends on the installation.

In order to get an overview of the commands, run dp2 help:
