The Busybox developers have released version 1.37.0, with some 50 changes.
Its developers call Busybox the “Swiss Army knife” of embedded Linux, because in one relatively small tool, it implements not just a Unix-style shell, but also about 300 different commands that are normally external programs in their own right. As a result, it’s often found inside devices that use Linux in very resource-constrained environments, such as consumer firewall/routers.
