Piper README

============

Piper is a simple library for python that allows you to easily executed piped

shell statements, and retrieve the output.

Actually, it doesn't do much but generate the Popen() statements for you, link

the stdin/stdout and return the output for you.  

As an example, the following statements are all equivalent:

Examples

--------

Shell:

  $ lsof -T | grep inode | cut -d ' ' -f 1 | sort -u

Python:

  p1=Popen(['lsof','T'],stdout=PIPE)

  p2=Popen(['grep','inode'],stdin=p1.stdout,stdout=PIPE)

  p3=Popen(['cut','-d',' ','-f','1'],stdin=p2.stdout,stdout=PIPE)

  p4=Popen(['sort','-u'],stdin=p3.stdout,stdout=PIPE)

  print p4.communicate()[0],

Python w/Piper:

  p=Piper()

  print p.run("lsof -T | grep inode | cut -d ' ' -f 1 | sort -u")
