The Linux Foundation gives a free Introduction to Linux course with the software created by Harward and MIT:
On March 6, the Linux Foundation announced it is building a Massive Open Online Course (MOOC) program with edX, the nonprofit, open source based, online learning platform launched in 2012 by Harvard University and Massachusetts Institute of Technology (MIT). The course: LFS101x is based on the popular LFS101: Introduction to Linux, with modifications which reflect the fact that it will be 100% self-paced. LFS101x will be availble entirely free of charge and as open enrollment, meaning that students can start the course at any time. We expect this course to become available during late Summer 2014 and users may pre-register on the course page at the edX website.
