For my courses ofwork in Linux command line not only for MetaCentrum and with molecular data in R I provide VirtualBox image, which allows to run complete desktop Linux (in this case openSUSE Leap) with all preinstalled applications needed for both courses. It's easy way how to get fully working Linux to play with. It requires at least bit powerful notebook, e.g. at least quad-core with at least 8 GB RAM, but more is better.
