如何在Bash中遍历JSON并更新auditX对象的password字段

Fixing the Initial Error #

Your original jq command fails because .[] iterates all top-level values, including the string storageSummary. The has() function only works on objects, so calling it on a string throws an error. To fix this, first filter for values that are objects before checking for the auditScore key:

jq '.[] | select(type == "object" and has("auditScore"))' input.json

This command will only return the audit1, audit2, audit3 objects, skipping storageSummary entirely.

Updating Password Fields in the Original JSON #

If you want to modify the password fields directly in the JSON file (keeping storageSummary intact), use map_values to conditionally update only the audit objects:

# Replace "new_secure_password" with your desired password
jq 'map_values(if type == "object" and has("auditScore") then .password = "new_secure_password" else . end)' input.json > updated_input.json

This will:

• Preserve the storageSummary field as-is
• Set the password field to your new value in all audit objects
• Write the modified JSON to updated_input.json

Processing Audit Objects in a Bash Loop #

To integrate this into a Bash loop for custom password updates (e.g., per-satellite passwords), output each audit object as a compact JSON line with -c, then loop through them:

jq -c '.[] | select(type == "object" and has("auditScore"))' input.json | while read -r audit_obj; do
    # Extract satellite name from the JSON object
    satellite=$(echo "$audit_obj" | jq -r '.satelliteName')
    
    # Replace with your actual password update logic
    echo "Updating password for satellite: $satellite"
    # Example: some_command --satellite "$satellite" --new-password "your_custom_pass"
    
    # If you need to modify the JSON object and save it separately
    # echo "$audit_obj" | jq '.password = "custom_pass_for_$satellite"' > "updated_$satellite.json"
done

This approach safely handles each audit object individually, letting you run custom operations per satellite.
