ReactOS是一些高手根据Windows XP的内核编写出的类XP。内核实现机理和API函数调用几乎相同。甚至可以兼容XP的程序。喜欢研究系统内核的人可以看一看。

FreeDOS Command Line Interface Development History

~~~~~~~~~~~~~~~~~~~~~
o  initial release.

01/01/95 version 0.10

o  removed some scaffolding.
o  modified CD.
o  added tab file completion.
o  added command line history.

01/15/95 version 0.20
~~~~~~~~~~~~~~~~~~~~~
o  formatted all existing source modules.
o  added prompt support.

        [ 08/08/95 -- Matt Rains ]
o  formatted this development log.
o  formatted all existing source modules so that they comply with recommended
        programming practice.
o  added MD command.
o  added RD command.
o  added VER command.
o  replaced CD command.
o  modified DIR command.
o  DIR now called regardless of other DIR.??? files. this is done because of
        exec() problems.

12/10/95 version 0.30
~~~~~~~~~~~~~~~~~~~~~
o  used Borland's spawnve to fix exec problem
o  fixed CD again so you don't need a space after it
o  couple of spelling fixes

12/14/95 version 0.31
~~~~~~~~~~~~~~~~~~~~~
o  modified cmdinput.c to work with non-standard screen sizes (see 28.com)
o  fixed a bug in history.c that made it not work when you hit the up arrow
   on the first line
o  fixed DIR to work a little more like MS-DOS's DIR (see internal.c)
o  fixed some code in where.c to make things a bit more efficient and nicer

01/06/96 version 0.40  (never released)
~~~~~~~~~~~~~~~~~~~~~
o  added redirection and piping support!!!  (see redir.c and command.c)
o  fixed a stupid pointer problem in where.c that was causing LOTS of
   problems in the strangest places...
o  added day of the week support to prompt.c (oops, that was already supposed
   to be there! :)
o  fixed and reorganized the EXEC code!!!  Thanks to Svante Frey!
o  reorganized command.c and internal.c to handle parsing internal commands
   more efficiently and consistently.
o  changed the behavior of MD, CD, RD to work without spaces (e.g. CD\DOS)
o  small changes here and there to make it work with redirection/piping
   (e.g. DIR only pauses if you're not doing redirection)

01/17/96 version 0.50
~~~~~~~~~~~~~~~~~~~~~
Version 0.40 was never released because I was home on Christmas vacation,
and I couldn't upload it.  By the time I got back to school, I had the
LOADHIGH patch from Svante Frey, so I decided to jump up to 0.50 without any
release of 0.40...       - Tim Norman

o  LOADHIGH/LOADFIX/LH support added!!!!  Many thanks go to Svante Frey!

o Added wildcard support for DEL command
o Added prompt and help switch for DEL command, /P and /?
  respectively.

batch.c
  A new version, implements CALL, ECHO, GOT, IF, PAUSE, SHIFT and
  BEEP. There is a stub for FOR but that's all.

  of the table real soon now and replacing it with a dynamic
  mechanism.

  Cleaned up (and fixed) the redirection handler.

command.h

  impliment _dos_getdate, _dos_setdate, _dos_gettime and _dos_settime.
  This is the first of many steps to make the shell compatible under
  Pacific C.

30-Jul-1998 (John P Price <[e-mail]>)
