Working with data in the UNIX shell

The UNIX shell is a useful environment to get work done. There're a number of
standard, simple tools that talk to each other via a universal interface: the
pipeline. This talk focuses on methods to manipulate and visualize data directly
in the shell, without moving to specialized environments (numpy, matlab, etc).
Specifically I will demonstrate and describe

feedgnuplot - a tool plot data coming in on STDIN
vnlog - a toolkit to read, write and manipulate columnar ASCII data

These are independent tools that are useful standalone, or in any combination
with other standard UNIX tools. This unification of data processing and normal
shell usage enable powerful workflows that are otherwise unavailable.
