Linux FAQs with Answers--How to check weather forecasts from the command line on Linux
|
|
================================================================================
|
|
> **Question**: I often check local weather forecasts on the Linux desktop. However, is there an easy way to access weather forecast information in the terminal environment, where I don't have access to desktop widgets or web browser?
|
|
|
|
For Linux desktop users, there are many ways to access weather forecasts, e.g., using standalone weather apps, desktop widgets, or panel applets. If your work environment is terminal-based, there are also several ways to access weather forecasts from the command line.
|
|
|
|
Among them is [wego][1], **a cute little weather app for the terminal**. Using an ncurses-based fancy interface, this command-line app allows you to see current weather conditions and forecasts at a glance. It retrieves the weather forecasts for the next 5 days via a weather forecast API.

### Install Wego on Linux ###
|
|
|
|
Installation of wego is pretty simple. wego is written in Go language, thus the first step is to [install Go language][2]. After installing Go, proceed to install wego as follows.
|
|
|
|
$ go get github.com/schachmat/wego
|
|
|
|
The wego tool will be installed under $GOPATH/bin. So add $GOPATH/bin to your $PATH variable.
|
|
|
|
$ echo 'export PATH="$PATH:$GOPATH/bin"' >> ~/.bashrc
|
|
$ source ~/.bashrc
|
|
|
|
Now go ahead and invoke wego from the command line.
|
|
|
|
$ wego
|
|
|
|
The first time you run wego, it will generate a config file (~/.wegorc), where you need to specify a weather API key.
|
|
|
|
You can obtain a free API key from [worldweatheronline.com][3]. Free sign-up is quick and easy. You only need a valid email address.
|
|
|
|
|
|
|
|
Your .wegorc will look like the following.
|
|
|
|
|
|
|
|
Other than API key, you can specify in ~/.wegorc your preferred location, use of metric/imperial units, and language.
|
|
|
|
Note that the weather API is rate-limited; 5 queries per second, and 250 queries per day.
|
|
|
|
When you invoke wego command again, you will see the latest weather forecast (of your preferred location), shown as follows.
|
|
|
|
|
|
|
|
The displayed weather information includes: (1) temperature, (2) wind direction and speed, (3) viewing distance, and (4) precipitation amount and probability.
|
|
|
|
By default, it will show 3-day weather forecast. To change this behavior, you can supply the number of days (upto five) as an argument. For example, to see 5-day forecast:
|
|
|
|
$ wego 5
|
|
|
|
If you want to check the weather of any other location, you can specify the city name.
|
|
|
|
$ wego Seattle
|
|
|
|
### Troubleshooting ###
|
|
|
|
1. You encounter the following error while running wego.
|
|
|
|
user: Current not implemented on linux/amd64
|
|
|
|
This error can happen when you run wego on a platform which is not supported by the native Go compiler gc (e.g., Fedora). In that case, you can compile the program using gccgo, a compiler-frontend for Go language. This can be done as follows.
|
|
|
|
$ sudo yum install gcc-go
|
|
$ go get -compiler=gccgo github.com/schachmat/wego
