nes-proj/apps/shell/shell-netfile.c
adamdunkels a26d87e09e Rewrite of the old Contiki shell. The new shell supports dynamic
insertion of new commands and command pipelining. There are also a
bunch of new commands for network access (using Rime): ping, data
collection, packet sniffing, sending shell commands across the
network, and testing the single-hop throughput to neighboring
nodes. Commands are also available for reading from and writing to
files, reading the sensors (on the Tmote Sky platform), and accessing
the power and energy consumption of the system. Dynamic loading of
programs across the network is also possible, although a little
untested at the moment.
