+BusyBox v1.27.2 (2018-04-23 15:08:10 EDT) multi-call binary.
+BusyBox is copyrighted by many authors between 1998-2015.
+Licensed under GPLv2. See source distribution for detailed
+copyright notices.
+
+Usage: busybox [function [arguments]...]
+   or: busybox --list[-full]
+   or: busybox --install [-s] [DIR]
+   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.
