To search for text in files from the current folder (or directory, to follow Linux nomenclature), one can write:

grep "text" -R . -n --include=*.py 

The parameters are as follows:

text                    the actual text to search for
-R                      Recurse to subdirectories
.                       start from the current directory
–include=*.py           specifies a regular expression that searchable files must match (e.g. *.py)

Introduction

Virtualenv is a tool to build isolated Python environments. It's a great way to quickly test new libraries without cluttering your global site-packages or run multiple projects on the same machine which depend on a particular library but not the same version of the library.

You can, for example, install version X of a library in one environment and version Z of the same library in another environment, without one interfering the other. Each environment provides its own Python executable and site-packages directory (which is not shared between environments).

Quickstart Command Sampler

$ easy_install virtualenv
