Readme

how2: stackoverflow from the terminal
NPM Version
how2 finds the simplest way to do something in a unix shell. It's like man, but you can query it in natural language:
Demo of using how2

Install

You can install it via npm:
npm install -g how-2
if it gives you EACCES errors, you need to fix npm permissions. Or you can just use sudo npm install -g how-2 if you don't care.

Usage

If you don't specify a language it defaults to Bash unix command line. how2 tries to give you immediately the most likely answer:
how2 unzip bz2
After that you can press SPACE to go to the interactive mode, where you can choose a different stackoverflow question/answer.
how2 interactive mode
how2 interactive mode 2
You can use -l lang to find answers for other languages:
-l python

Copy-Paste with mouse

When you are in "interactive mode" (after you press SPACE), if you want to copy-paste more than one line you can use block-select:
With Ubuntu try holding Ctrl+Alt before you select, or Alt+Cmd if you're in iTerm on Mac.
(thanks to @danielkop for this suggestion).

Can i use it behind Proxy ?

Yes, you need to use HTTP_PROXY or HTTPS_PROXY environment variables.
For example, you could alias the proxy seetings in your ~/.bash_profile:
alias how2="HTTPS_PROXY='your_proxy:8888' how2"

How does it work?

It uses Google and Stackoverflow APIs, because Stackoverflow search on its own doesn't works as well.

Why?

Because I can never remember how to do certain things. And reading man pages always takes too long.
