Linux Foundation LFS201 / Linux Foundation Certified System Administrator Exam Prep Course
This repo contains all of the downloaded PDFs, some code, and my Markdown notes taken during the self-paced online LFS201 course hosted by the Linux Foundation. I hope to take the certification exam in October 2019.
Disclaimer: Most emphasis (whether italics or bold type) used in these documents are from the course materials, but some have been added by me. All screenshots are from course materials. I do not own the images. PDFs are created from the Markdown notes, and as such the Markdown notes will (usually) be more current than the PDFs. The PDF containing all chapters may be updated periodically, but will usually be out of date if any changes are made to the Markdown notes.
