pipeline is a tool to help with quick iteration on complex shell pipelines.

Pipe some data into pipeline, and edit your pipeline while watching the output in real time. When you're satisfied, hit return to have its output piped to the next stage. Or, hit ctrl-c or escape to cancel and exit 1 with no output.

Evaluation will be 'off' until you terminate the pipeline with a ;, making it easier to avoid running bad intermediate commands (like, if the prefix of a command was rm...).
