    So how does one bootstrap a development system from the command line?

A few years ago I mused about bootstrapping a development system under MS-DOS
from the command line [1]. Now, I personally haven't done that, but I can see
how it could be done.

But Edmund Evans came close to doing just that [2] (link via Hacker News
[3]). He “cheated” by having a program that converted hex codes to binary.
It's not that bad though, under Linux, you have a bit of an easier time
generating binary data:

> /bin/echo -e "\177\105\114\106\001\001\001\000..." >hex1
>

(it's coincidental that this method also uses octal values instead of hex—
Unix began life in an octal environment).

That small quibble aside, Edmund did the bootstrapping procedure pretty much
how I envisioned it.

And in following a few more links from the Hackers News commentary [4], I see
that Kragen Sitaker referenced my previous entry and did the initial
bootstrap [5] (making a program to read text into binary) from the MS-DOS
command line (how odd—that mailing list with only one member [6]).
