I add mycmd to ash.c ash: addbyyang: not found What's wrong with the Built-in shell (ash)

[ruifeng yang]

Hello everyone:

   I am reading the busybox's sources,the busybox version is 1.00.
I want to add mycmd in the ash.c:
   I add :
   { BUILTIN_REGULAR       "addbyyang", addbyyangcmd },
   to the static const struct builtincmd builtincmd[]=.
   and add:
   static int addbyyangcmd(int, char **);
   to the 1281 cow in the ash.c.

   I make and make install the sources.I try the cmd but I get this:
   /home/yrff/busybox-1.00/_install/bin # ./busybox ash


   BusyBox v1.00 (2009.04.14-01:06+0000) Built-in shell (ash)
   Enter 'help' for a list of built-in commands.

   /home/yrff/busybox-1.00/_install/bin # help

   Built-in commands:
   -------------------
           . : alias bg break cd chdir continue eval exec exit export false
           fg hash help jobs kill let local pwd read readonly return set
           shift times trap true addbyyang type ulimit umask unalias unset
           wait

   /home/yrff/busybox-1.00/_install/bin # addbyyang
   ash: addbyyang: not found
   /home/yrff/busybox-1.00/_install/bin #

  What is wrong with the ash.c by my modified? help me!
  Thank you!
