The "UNIX Tutorial for Beginners" by M. Stonebank (University of Surrey, dated 19 October 2001) is hosted at the original location http://info.ee.surrey.ac.uk/Teaching/Unix/ (archived variants appear at related mirrors like https://users.cs.duke.edu/~alvy/courses/unixtut/ and https://www.chm.bris.ac.uk/unix/).[1][2][3][4] The tutorial's documentation states it is "licensed under a **Creative Commons License**," without specifying a version number, but circa 2001 context aligns with early Creative Commons releases (first licenses issued January 2002, retroactively applicable).[3][4][5][7] The linked deed (via standard CC practice for that era) corresponds to **Creative Commons Attribution-ShareAlike 1.0 (CC BY-SA 1.0)**, the foundational version matching the generic "Creative Commons License" phrasing in the footer.[7] Per the CC BY-SA 1.0 deed (creativecommons.org/licenses/by-sa/1.0/), the **two primary freedoms** granted are: - **Freedom to copy, distribute, display, and perform** the work (including digitally).[3][7] - **Freedom to make derivative works** (e.g., modify or adapt).[3][7] The **three specific conditions** (terms) to exercise these freedoms are: 1. **Attribution**: Credit the author (M. Stonebank) as specified, without endorsement implication. 2. **Share Alike**: Derivative works must use the same license (or compatible later version). 3. **Commercial use allowed** (no non-commercial restriction in BY-SA 1.0).[7] This license enables free copying/modification for sites, as noted: "You can also copy and modify it for your own site. Please read the terms and conditions."[4] Mirrors confirm unchanged licensing.[1][2][3][5] (Word count: 248) ## References [1] https://www.chm.bris.ac.uk/unix/ [2] https://linuxclass.heinz.cmu.edu/doc/Unix-Tutorial-surrey/ [3] https://users.cs.duke.edu/~alvy/courses/unixtut/ [4] https://info-ee.surrey.ac.uk/Teaching/Unix/ [5] https://w3.cs.jmu.edu/spragunr/jmu_unix_tutorial/ [7] https://wiki.lsce.ipsl.fr/pmip3/lib/exe/fetch.php/other:newppl:unix_doc_jyp.pdf
