- # Get random subject from English Wikipedia #
- # #
- #############################################
- # Logic behind this is as follows:-
- #
- # 1. Grab a random page from wikipedia using wget, and keep output quiet - save as temp file
- # 2. Pipe the resulting html into grep, only looking for the line that containers the page <title> - equivalent to subject
- # 3. Strip the opening html tag using cut
- # 4. Reverse the string from that line
- # 5. Remove the closing title tag, and the " - Wikipedia" portion of thepage title
- # 6. Reverse the string back to normal orientation, to keep it human-readable, and output to stdout
- # 7. Remove temp file
- wget -O temp.html -q https://en.wikipedia.org/wiki/Special:Random
- cat temp.html | grep "<title>" | cut -c 8- | rev | cut -c 21- | rev
- rm temp.html
- # Although this is just a simple script and could be incorporated into any script, I can
- # forsee a few use-cases where getting a random subject from Wikipedia to be useful.
- # And, ya know, UNIX philosphy - do one thing and do it well
- # This is part of my web-use "Chaffer" - props to Cory Doctorow's book homeland for the impetus
