In the same vein of 'improvements over things everyone assumes you have to do with the more famous tool', we could say grep '^string' : look :: sort -R : shuf

- nhaehnle 11y agoThanks to @climagic on Twitter, I recently learned that sort -R and shuf are not in fact the same thing. (sort -R doesn't actually shuffle...)
- cfcef 11y agoMy point there was that besides being a true shuffle, 'shuf' also has an algorithmic advantage when you only need a few lines (similar to how lookup has an advantage when you only need a few).
- ryan-c 11y agolook does a binary search and only works on sorted files, while grep '^string' works on any text file but would be slower.
