continuity

I guess this could be construed as cheating, but I finished a poem for the 23rd of December.

Here is a brief list of interesting things in the GNU coreutils that I did not know about until recently:

  • od dumps files in octal and other formats.
  • shuf randomly shuffles its input.
  • seq prints a sequence of numbers. No, really, I didn't know this existed.
  • ptx produces a permuted index of a file. Try this on a text of some length. It's especially interesting on verse or lyrics. For example, here's its output for the 23rd's poem, and here's what it does with the lyrics to "California Stars" (source).
