问题
I have a complex JSON file and I am trying to get the below result using JQ.
Expected Result:
{
"Host": "Test.example.com",
"Title": "Ensure message of the day is configured properly",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure bond0 is present",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure the SELinux state is disabled",
"Status": "passed"
}
Below is the JSON file that I get as a result of running an Chef Inspec profile.

I used the following JQ code to extract the fields , but the extracted values are repeating.
JQ Code:
jq '{Host: .platform.target_id,Title: .profiles[].controls[].title,Status: .profiles[].controls[].results[].status}'
The result which I got from above JQ filter
Actual Result:
{
"Host": "Test.example.com",
"Title": "Ensure message of the day is configured properly",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure message of the day is configured properly",
"Status": "skipped"
}
{
"Host": "Test.example.com",
"Title": "Ensure message of the day is configured properly",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure bond0 is present",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure bond0 is present",
"Status": "skipped"
}
{
"Host": "Test.example.com",
"Title": "Ensure bond0 is present",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure the SELinux state is disabled",
"Status": "passed"
}
{
"Host": "Test.example.com",
"Title": "Ensure the SELinux state is disabled",
"Status": "skipped"
}
{
"Host": "Test.example.com",
"Title": "Ensure the SELinux state is disabled",
"Status": "passed"
}
How can I get the expected results. Any help would be appreciated.
回答1:
Because you're iterating over profiles[] more than once, you're combining the results of one such iteration with the results of another. To avoid that, iterate only once, and get both title and results from the same controls list entry.
jq '
.platform.target_id as $target |
.profiles[].controls[] |
{ Host: $target,
Title: .title,
Status: .results[].status }
'
