    Abstract

    A multi-call binary is an executable, written in C, that performs the action of more than one utility. A prime example of a multi-call binary is the BusyBox package. BusyBox implements a large number of standard Linux utilities (such as the ls and ln commands) in a single executable. This enables specialized Linux distributions to have a reduced size. This tip describes how multi-call binaries are written.
