The pipes Module

(Unix only) The pipes module shown in Example 3-8 contains support functions to create "conversion pipelines." You can create a pipeline consisting of a number of external utilities and use it on one or more files.

Example 3-8. Using the pipes Module

File: pipes-example-1.py

import pipes

t = pipes.Template()

# create a pipeline
t.append("sort", "--")
t.append("uniq", "--")

# filter some text
t.copy("samples/sample.txt", "")
