This is the interactive interface for commits in Darcs. It uses the same interface for pushing and pulling, where I mostly use y/n/a/d but sometimes the other letters too.

**** Shall I record this change? (1/?) [ynWsfqadjkc], or ? for help: ? How to use record... y: record this patch n: don't record it w: wait and decide later, defaulting to no

s: don't record the rest of the changes to this file f: record the rest of the changes to this file

d: record selected patches, skipping all the remaining patches a: record all the remaining patches q: cancel record

j: skip to next patch k: back up to previous patch c: calculate number of patches h or ?: show this help

<Space>: accept the current default (which is capitalized) ****

If you want to get a feel for it, grab darcs and run

  darcs init
  echo hello > hello
  darcs add
  darcs record

For a really neat implementation of per-hunk commits, try running darcsum in Emacs

am I running the wrong bash? it barf on this. Don't you mean $(echo ... )

Frankly, I am amazed that people write things in bash at all--I vowed never to write bash again a couple of years ago. If you start doing arrays and counting, wouldn't a more high-level language be suitable?
