The hard part in becoming a command line wizard
I can't beat this for terseness, but I think I could whip up something close (say 15 lines) in Python (readable) or Perl (would be shorter than Python but more readable than linux).I guess I am more curious about what Knuth did! Did he just comment it a lot for "literate" code?As always I feel the Python (or Ruby if I could write it) is the sweet spot between being easy to read and easy to write.
