It's also much nicer looking and more interactive, FWIW...I also agree with its defaults.

    $ howdoi inverse grep a file

Simply pops this up:

      $ grep -L "foo" *

...apparently it scrapes the answer result and print the last occurrence of code-formatted text.

Whereas `how2` pretty-prints the entire answer, narrative and code, so I know what the respondent was actually addressing. FWIW, both tools don't address what I want (I was thinking `grep -v`)...but that's not a fault of the tools, but of the ambiguity in how we ask questions. `howdoi` has far more faith in there being "Just One Answer"...where `how2` let's you move very quickly between the relevant choices, giving you the right amount of context to navigate.

Well done OP!
