Display Weather Forecast In Your Terminal With Wttr.in
|
|
======
|
|
**[wttr.in][1] is a feature-packed weather forecast service that supports displaying the weather from the command line**. It can automatically detect your location (based on your IP address), supports specifying the location or searching for a geographical location (like a site in a city, a mountain and so on), and much more. Oh, and **you don't have to install it - all you need to use it is cURL or Wget** (see below).
|
|
|
|
wttr.in features include:
|
|
|
|
* **displays the current weather as well as a 3-day weather forecast, split into morning, noon, evening and night** (includes temperature range, wind speed and direction, viewing distance, precipitation amount and probability)
|
|
|
|
* **can display Moon phases**
|
|
|
|
* **automatic location detection based on your IP address**
|
|
|
|
* **allows specifying a location using the city name, 3-letter airport code, area code, GPS coordinates, IP address, or domain name**. You can also specify a geographical location like a lake, mountain, landmark, and so on)
|
|
|
|
* **supports multilingual location names** (the query string must be specified in Unicode)
|
|
|
|
* **supports specifying the language** in which the weather forecast should be displayed in (it supports more than 50 languages)
|
|
|
|
* **it uses USCS units for queries from the USA and the metric system for the rest of the world** , but you can change this by appending `?u` for USCS, and `?m` for the metric system (SI)
|
|
|
|
* **3 output formats: ANSI for the terminal, HTML for the browser, and PNG**.

Like I mentioned in the beginning of the article, to use wttr.in, all you need is cURL or Wget, but you can also
|
|
|
|
**Before using wttr.in, make sure cURL is installed.** In Debian, Ubuntu or Linux Mint (and other Debian or Ubuntu-based Linux distributions), install cURL using this command:
|
|
```
|
|
sudo apt install curl
|
|
|
|
```
|
|
|
|
### wttr.in command line examples
|
|
|
|
Get the weather for your location (wttr.in tries to guess your location based on your IP address):
|
|
```
|
|
curl wttr.in
|
|
|
|
```
|
|
|
|
Force cURL to resolve names to IPv4 addresses (in case you're having issues with IPv6 and wttr.in) by adding `-4` after `curl` :
|
|
```
|
|
curl -4 wttr.in
|
|
|
|
```
|
|
|
|
**Wget also works** (instead of cURL) if you want to retrieve the current weather and forecast as a png, or if you use it like this:
|
|
```
|
|
wget -O- -q wttr.in
|
|
|
|
```
|
|
|
|
You can replace `curl` with `wget -O- -q` in all the commands below if you prefer Wget over cURL.
|
|
|
|
Specify the location:
|
|
```
|
|
curl wttr.in/Dublin
|
|
|
|
```
|
|
|
|
Display weather information for a landmark (the Eiffel Tower in this example):
|
|
```
|
|
curl wttr.in/~Eiffel+Tower
|
|
|
|
```
|
|
|
|
Get the weather information for an IP address' location (the IP below belongs to GitHub):
|
|
```
|
|
curl wttr.in/@192.30.253.113
|
|
|
|
```
|
|
|
|
Retrieve the weather using USCS units:
|
|
```
|
|
curl wttr.in/Paris?u
|
|
|
|
```
|
|
|
|
Force wttr.in to use the metric system (SI) if you're in the USA:
|
|
```
|
|
curl wttr.in/New+York?m
|
|
|
|
```
|
|
|
|
Use Wget to download the current weather and 3-day forecast as a PNG image:
|
|
```
|
|
wget wttr.in/Istanbul.png
|
|
|
|
```
|
|
|
|
You can specify the PNG
|
|
|
|
**For many other examples, check out the wttr.in[project page][2] or type this in a terminal:**
|
|
```
|
|
curl wttr.in/:help
|
|
|
|
```
