Does Eclipse work on Linux?

The latest releases should normally work fine on any recent Linux distribution. But the Linux graphical UI systems change fast and it is entirely possible that newer releases of Eclipse will not work on older distributions, and similarly older releases of Eclipse may not work on newer distributions.

How do I run eclipse from command line?

You can start Eclipse by running eclipse.exe on Windows or eclipse on other platforms. This small launcher essentially finds and loads the JVM. On Windows, the eclipsec.exe console executable can be used for improved command line behavior.
