Chapter 11.  > BusyBox Operation

11.3. BusyBox Operation

When you build BusyBox, you end up with a binary called, you guessed it, busybox. BusyBox can be invoked from the binary name itself, but it is more usually launched via a symlink. When BusyBox is invoked without command-line parameters, it produces a list of the functions that were enabled via the configuration. Listing 11-3 shows such an output (it has been formatted slightly to fit the page width).

Listing 11-3. BusyBox Usage

root@coyote # ./busybox
BusyBox v1.01 (2005.12.03-18:00+0000) multi-call binary

Usage: busybox [function] [arguments]...
       or: [function] [arguments]...

    BusyBox is a multi-call binary that combines many common Unix
    utilities into a single executable. Most people will create a
    link to busybox for each function they wish to use and BusyBox
    will act like whatever it was invoked as!
