I have a list of IP addresses in the ip.txt file (there are a lot of them).
I used ipinfo.io services to search data by IP and sed to cut out only the city.
#!/bin/bash
while IFS= read -r ip; do
curl ipinfo.io/$ip >> test.txt
sed -i '/city/!d' test.txt
cat /dev/null > test.txt
done < ip.txt
However, the script doesn`t display the city in a loop over all IPs (only works on individual data), but displays a lot of unnecessary information. For example, for the following IPs (generated automatically):
97.108.178.66
98.10.198.56
201.12.36.90
My output:
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 332 100 332 0 0 2145 0 --:--:-- --:--:-- --:--:-- 2155
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 323 100 323 0 0 1345 0 --:--:-- --:--:-- --:--:-- 1340
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
100 266 100 266 0 0 1426 0 --:--:-- --:--:-- --:--:-- 1430
Required output:
"city": "Toronto",
"city": "Rochester",
"city": "Rio de Janeiro",
How can this be done?
It's not clear whether you're trying to capture the cities in a text file or display them. If you want them stored, don't overwrite the results.
$ cat tmp
#!/bin/bash
while IFS= read -r ip; do
curl ipinfo.io/$ip >> test.txt 2>/dev/null
sed -i '/city/!d' test.txt
done < ip.txt
$ cat ip.txt
97.108.178.66
98.10.198.56
201.12.36.90
$ ./tmp
$ cat test.txt
"city": "Toronto",
"city": "Rochester",
"city": "Rio de Janeiro",
$
If you just want to see them on screen:
$ cat tmp
#!/bin/bash
while IFS= read -r ip; do
curl ipinfo.io/$ip 2>&1 | sed '/city/!d'
done < ip.txt
$ ./tmp
"city": "Toronto",
"city": "Rochester",
"city": "Rio de Janeiro",
$
