Pexpect

Pexpect is a super handy open-source library that's totally free! It's built with Python and acts like an Expect module, helping you spawn child applications, control them, and respond to what they throw at you. Pretty cool, right?

Easy Command-Line Interface

Pexpect gives you a user-friendly command-line interface (CLI) that makes it easy to handle various tasks without breaking a sweat. Plus, it comes with a VT100/ANSI terminal screen scraping module!

Automate Your Tasks

You can use Pexpect to automate interactive programs like FTP, SSH, or Telnet clients. It's also great for things like the passwd command and for automating setup scripts or software testing.

Duplicate Software Installations

Another neat trick? You can use this Python module to copy software package installations across multiple servers. If you're curious about how to get started or want some examples, check out the project's homepage for more info!

No Extra Dependencies Needed

One of the best parts about Pexpect is that it doesn't rely on Expect or TCL and doesn't need any compiled C extensions. This means it's really portable; you can run it on any operating system that has the pty Python module.

Simple Installation on Linux

If you're using a GNU/Linux distribution, installing Pexpect is a breeze. Just pop open your terminal emulator and run 'pip install pexpect'. Just make sure you have pip installed first!

Alternative Installation Method

If you prefer another way, you can download the latest version from Softpedia. Just save the archive on your computer, extract its contents, open your terminal emulator again, navigate to where you extracted it (like cd /home/softpedia/pexpect-3.3), and run 'sudo python setup.py install' as root.
