Bash script to show the public IP, city, region and timezone

In this tutorial, you will learn how to show the public IP, location and the timezone of your server/computer in a bash script, and then save the output into a text file.

There are a lot of sites where you can just visit them and they will show your public IP.However, sometimes you need this data returned on a terminal or other project, so to make this possible, a bash script would be the perfect choice to use.

The service that we are using for this tutorial is ipinfo.io.  You can also use any other service you like, including your own site.

The bash script below will return a json response as shown below, this response means this data is available that we can retrieve from ipinfo.io.  For example, if you want to retrieve country location then we need to call ipinfo.io/country

#!/bin/bash


curl ipinfo.io

Output

{
  "ip": "xxxx",
  "city": "x",
  "region": "x",
  "country": "x",
  "loc": "xxx",
  "org": "xxx",
  "postal": "xxxx",
  "timezone": "xxxxx",
  "readme": "x"

Show Public IP

To show your server's Public IP call ip on the bash script

#!/bin/bash

curl ipinfo.io/ip

Show Country

If you want to retrieve your server's country data, then you need to call country on the curl call

#!/bin/bash


curl ipinfo.io/country

Show Region

To display region simply call ipinfo.io/region

#!/bin/bash


curl ipinfo.io/region

Show City

To show city make a curl call to ipinfo.io/city

#!/bin/bash


curl ipinfo.io/city

Show timezone

To show the timezone of the server from where you are executing the bash script, use

#!/bin/bash


curl ipinfo.io/timezone

Save the output into a file

If you want to save the output data depending the call that you are making on the bash script, then you can use the example below

#!/bin/bash





country="$(curl ipinfo.io/country)"

echo $country >> country.txt 

This script will not display the country on the terminal but it will write it to the country.txt file instead. If you want to get the script to display the country in the terminal and in the country.txt file at the same time, then you can use >> to append the data to a file and cat command to read the content of country.txt

#!/bin/bash





country="$(curl ipinfo.io/country --silent)"

echo "Country: "$country >> country.txt 
cat country.txt

Conclusion

In this tutorial, you learned how to make a bash script to get public data about your system.
