Let’s have fun with Linux Terminal today. Also, if you are developer, let’s reduce one context switch that you perform while development; switching to browser for solution in stackoverflow. It's well known fact, less context switch, less distraction and more productivity. In this article we’ll explore two fun and useful things that you can do right through terminal without opening browser that you would do normally.


WEATHER INFO THROUGH TERMINAL IN BEAUTIFUL WAY!


Install curl [optional]

Before you can use the API of wttr.in you need to install curl in your system.

For Debian based system,

sudo apt-get install curl

For fedora based system,

sudo dnf install curl

This is optional installation. Alternatively, you can use wget command to get weather info as explained later in this section.

Getting Weather

http://wttr.in/ provides api that returns weather information of location in decorated way. To get weather information,

Open terminal. (shortcut : ctrl + alt + T).
Type command :

curl wttr.in

You will see weather forecast layout for your location for three days with current wind speed.

To check weather forecast of particular place, you can use command curl wttr.in/place

Getting Weather Forecast Through WGET

If you don't have installed curl, you can use prebundled wget command by getting its output on terminal. By default, wget command stores output in file. You need to use -qO- command line parameter to get output on terminal screen.

wget -qO- wttr.in/Mumbai

SURFING STACKOVERFLOW.COM THROUGH TERMINAL


Claudio Santini, A London based developer had an idea on this line, why not having stackoverflow.com surfing right through terminal.
An opensource project how2 from Santini (hosted on gthub: here exactly does this. Although the wiki page provides you help in installation of how2, let’s explore this utility.

Installing HOW2

  1. Install npm. Follow this command
    sudo apt-get update
    sudo apt-get install npm
  2. Install nodejs
    sudo apt-get install nodejs
  3. Install how2
    sudo npm install -g how2
NOTE: There is known bug in debian system’s linux. It uses its internal node command instead of nodejs one. In case you encounter error even after successful installation: ERROR : /usr/bin/env: node: No such file or directory
Do the following changes:
ln -s /usr/bin/nodejs /usr/bin/node

Using HOW2

Using how2 is simple as other linux commands.It takes syntaxt,

how2 [optionaParameters] your Query.

For example if I want to surf how to write if statement in shell script, I would type command:

how2 write if in shell script
