I'm not sure what you mean by the 'kdb command'. There is no such
command that can be executed from a shell. To invoke KDB, one either
uses the keyboard sequences (pause key on PC keyboard, control-a on
serial port) or uses the 'kdb' flag to lilo causing kdb to gain control
of the kernel early in the boot process. From there, one can set
breakpoints, examine kernel memory, check thread stacks, etc.
