Busybox and Other Help Programs

Busybox combines many programs from the standard Linux distributions into one
program in order to minimize memory requirements in the file system. The
program is called up through symbolic links only. Busybox evaluates names being
called up and can, in this way, implement different functions in one program
together.
The following programs, among others, are made available by Busybox:
•
mount
Integrating drives
By choosing the name (PC: format > volume label) of integrated memory
media (e.g. CF card, USB memory), these are indicated in the file system
(/media).
•
reboot
Restart the I/O-IPC
•
ifconfig
Indicates current ETHERNET interface settings. Use WBM or IPC-
Configuration-Tool to change these settings.
•
rmdir
Delete directory
•
reboot
Restart the I/O-IPC
Compiling Busybox
When compiling from Busybox, you can determine which programs are to be
integrated. In doing so, you adapt the program size according to the required
function. In the I/O-IPC, all the functions necessary for a minimal system are
implemented.
