script by Carsten Brueggenolte
This is a simple bash script to check weather condition
with the help of wttr.in. The script 'wttr' is under GPL3 License.
Source is available on Github: $GITHUB_REPO_URL
Big THANK YOU goes to
- 'Amirreza Firoozi' (https://github.com/AmirrezaFiroozi/wttr)
for creating the initial script
- 'doc-ock' (https://github.com/doc-ock/) for the idea to add
version 3 of wttr.in and some other useful parameters.

echo -e "
Write 'wttr {your+city+name}' to check the weather condition of your city.
Surround city name with single- or double-quotes if city name contains more than one word.
You can also put a '+' (plus-sign) in beetween words when you do not want to surround with quotes.
Examples:
wttr cologne
wttr \"Den Haag, Netherland\"
wttr Den+Haag
wttr \"Den Haag Street, South Africa\"
wttr New+York
You can type 'wttr' only if you have defined a standard city.
Parameters:
-a show some information about this script
-h for some help (this page)
-hh for the official wttr.in/:help page
-i to install curl which is necessary for script to run correctly
-m for photo of moon
-n show current weather only
-rm to remove the script :(
-sdef to define a city as your default city
-t show today's forecast
-v show script version
-v2 to fetch different weather report view for the standard city
-v2 {your city name} to fetch different weather report view for city mentioned
-v3 {your city name} to fetch an in-terminal graphic for the given region.
Hint:
When using '-v3' you do not need to add the '.sxl' to the
end of the region/city name. The script will add it automatically.
