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?
