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
|
||||
|
||||
```

使用 Wttr.in 在你的终端中显示天气预报
|
||||
======
|
||||
**[wttr.in][1] 是一个功能丰富的天气预报服务，它支持在命令行显示天气**。它可以自动检测你的位置（根据你的 IP 地址），支持指定位置或搜索地理位置（如城市、山区等）等。哦，另外**你不需要安装它 - 你只需要使用 cURL 或 Wget**（见下文）。
|
||||
|
||||
wttr.in 功能包括：
|
||||
|
||||
* **显示当前天气以及 3 天天气预报，分为早晨、中午、傍晚和夜晚**（包括温度范围、风速和风向、可见度、降水量和概率）
|
||||
|
||||
* **可以显示月相**
|
||||
|
||||
* **基于你的 IP 地址自动检测位置**
|
||||
|
||||
* **允许指定城市名称、3 字母的机场代码、区域代码、GPS 坐标、IP 地址或域名**。你还可以指定地理位置，如湖泊、山脉、地标等）
|
||||
|
||||
* **支持多语言位置名称**（查询字符串必须以 Unicode 指定）
|
||||
|
||||
* **支持指定**天气预报显示的语言（它支持超过 50 种语言）
|
||||
|
||||
* **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)
|
||||
* **来自美国的查询使用 USCS 单位用于，世界其他地方使用公制系统**，但你可以通过附加 `?u` 使用 USCS，附加 `?m` 使用公制系统。 ）
|
||||
|
||||
* **3 种输出格式：终端的 ANSI，浏览器的 HTML 和 PNG**。
|
||||
|
||||
|
||||
|
||||
|
||||
就像我在文章开头提到的那样，使用 wttr.in，你只需要 cURL 或 Wget，但你也可以
|
||||
|
||||
**在使用 wttr.in 之前，请确保已安装 cURL。**在 Debian、Ubuntu 或 Linux Mint（以及其他基于 Debian 或 Ubuntu 的 Linux 发行版）中，使用以下命令安装 cURL：
|
||||
```
|
||||
sudo apt install curl
|
||||
|
||||
```
|
||||
|
||||
### wttr.in 命令行示例
|
||||
|
||||
获取你所在位置的天气（wttr.in 会根据你的 IP 地址猜测你的位置）：
|
||||
```
|
||||
curl wttr.in
|
||||
|
||||
```
|
||||
|
||||
通过在 `curl` 之后添加 `-4`，强制 cURL 将名称解析为 IPv4 地址（如果你遇到 IPv6 和 wttr.in 问题）：
|
||||
```
|
||||
curl -4 wttr.in
|
||||
|
||||
```
|
||||
|
||||
如果你想检索天气预报保存为 png，**还可以使用 Wget**（而不是 cURL），或者你想这样使用它：
|
||||
```
|
||||
wget -O- -q wttr.in
|
||||
|
||||
```
|
||||
|
||||
如果相对 cURL 你更喜欢 Wget ，可以在下面的所有命令中用 `wget -O- -q` 替换 `curl`。
|
||||
|
||||
指定位置：
|
||||
```
|
||||
curl wttr.in/Dublin
|
||||
|
||||
```
|
||||
|
||||
显示地标的天气信息（本例中为艾菲尔铁塔）：
|
||||
```
|
||||
curl wttr.in/~Eiffel+Tower
|
||||
|
||||
```
|
||||
|
||||
获取 IP 地址位置的天气信息（以下 IP 属于 GitHub）：
|
||||
```
|
||||
curl wttr.in/@192.30.253.113
|
||||
|
||||
```
|
||||
|
||||
使用 USCS 单位检索天气：
|
||||
```
|
||||
curl wttr.in/Paris?u
|
||||
|
||||
```
|
||||
|
||||
如果你在美国，强制 wttr.in 使用公制系统（SI）：
|
||||
```
|
||||
curl wttr.in/New+York?m
|
||||
|
||||
```
|
||||
|
||||
使用 Wget 将当前天气和 3 天预报下载为 PNG 图像：
|
||||
```
|
||||
wget wttr.in/Istanbul.png
|
||||
|
||||
```
|
||||
|
||||
你可以指定 PNG 名称
|
||||
|
||||
**对于其他示例，请查看 wttr.in [项目页面][2]或在终端中输入：**
|
||||
```
|
||||
curl wttr.in/:help
|
||||
|
||||
```
