how2 – Simple Way To Browse Stack Overflow From The Terminal

I am very much interested to write CLI related applications as i was spending most of the time with terminal (in other hand, we can say it’s a black screen).

Stack Overflow is the largest, most trusted online community for developers to learn, share​ ​their programming ​knowledge, and build their careers. It’s world’s largest developer community and allows users to ask and answer questions.

It’s open alternative to earlier question and answer sites such as Experts-Exchange.

We had written about the same topic in our previous article, the tool name is called SoCLI. Today also we are going to discuss about the same topic called how2.

As we discussed many times, everything is possible in Linux. We would get many options as well (i mean, we get multiple applications for the same purpose, each application has it’s own unique features).

How to Install how2

how2 is built on nodejs and we can be install via npm package manager. If you didn’t install npm & nodeJS package already, run the following command to install it.

For Debian/Ubuntu users, use Apt Command or Apt-Get Command to install npm package.

$ sudo apt install npm

For Archlinux users, use Pacman Command to install npm package.

$ sudo pacman -S npm

For Fedora users, use DNF Command to install npm package.

$ sudo dnf install npm

For CentOS/RHEL users, use YUM Command to install npm package.

$ sudo yum install npm

For openSUSE users, use Zypper Command to install npm package.

$ sudo zypper install npm

Finally run the following npm command to install how2 tool.

$ sudo npm install -g how-2

How Use how2

It uses native standard Linux command format. This tool search the given string right from the terminal.

I got an error in the above result, which i marked in red color box. I did small google search and found the solution, just add the below value into transport.js file to fix it.

If you don’t know the transport.js file location. Use the below find command to figure it out.

$ sudo find / -name transport.js
/usr/local/lib/node_modules/how2/node_modules/devnull/transports/transport.js

If you had found the file in then you have to make the below change to fix it.

$ sudo vi /usr/local/lib/node_modules/how2/node_modules/devnull/transports/transport.js
From:
var EventEmitter = process.EventEmitter;

To:
var EventEmitter = require('events')

Yes, now i got a result without any error awesome, it’s gone.

If you want to see related questions and answer for the above question, just hit SPACE.

Select the topic which you want to read using UP/DOWN button then hit SPACE or Enter to view the answer in interactive mode.

If you would like to search about particular language related questions, use -l option with how2.

$ how2 -l shell "script to get uptime in multiple servers"

Conclusion

This tool done it jobs as expected, it doesn’t has advanced options such as interactive search, topic based search, post new question, etc,.

I would suggest you to use SoCLI utility, if you are looking more professional tool. If you are looking for basic Stack Overflow search then you can stick with this tool.
