Running Understand on a Headless Linux Server

While we strongly recommend familiarizing yourself with the GUI first, command line functionality is very available in Understand. Projects, reports and metrics can be created using the tool und. And there are several API’s available for accessing the information programmatically. Note that generating graphs from the command line or using the APIs will still require that X11 be installed on the machine since the images are generated using X11 libraries.

To install Understand from the command line simply extract it from the .tgz bundle into the desired location. For example

wget http://builds.scitools.com/all_builds/b953/Understand/Understand-5.0.953-Linux-64bit.tgz

tar -xvzf Understand-5.0.953-Linux-64bit.tgz

Once extracted, license information will need to be entered using the appropriate method from below. You can test if there is a valid license by running Und in interactive mode (scitools/bin/linux64/und)

headless_linux_01
headless_linux_02

Details on specifying your license from the command line are here. In most cases you can just run

scitools/bin/linux64/und -setlicensecode XXXXXXXXXX
