eduX provides online computer based training. One course that caught my eye is module LFS101 – Introduction to Linux, provided by the Linux Foundation. This is a free course, scheduled for later this year.
No previous experience of Linux required, and covers a number of areas, suitable for Linux programmers, system administrators and end users.
