I have a super simple bash script...
#!/bin/bash
result=$(curl -i -H "Accept: application/json" -H "Content-Type: application/json" https://jsonplaceholder.typicode.com/posts/1)
I am trying to call a REST API and parse the response.
When I execute this script, I get this response, which is not what I want...
% Total % Received % Xferd Average Speed Time Time Time Current
Dload Upload Total Spent Left Speed
146 292 146 292 0 0 1106 0 --:--:-- --:--:-- --:--:-- 6790
When I run the curl command directly in my terminal, I get this response, which IS what I want...

}
Can someone point out what I'm missing please :)

To get the actual output of curl you can use the command directly in the script. or you can set the endpoint in a variable...
#!/bin/bash
result=https://jsonplaceholder.typicode.com/posts/1
curl -i -H "Accept: application/json" -H "Content-Type: application/json" $result
This can show you what you want.

You need to quote the result when you want to save it to a variable:
#!/bin/bash
result="$(curl -i -H "Accept: application/json" -H "Content-Type: application/json" https://jsonplaceholder.typicode.com/posts/1)"
echo the result is: "${result}"
The double quotes are important if you want to preserve multiple lines.
