files with many lines of JSON but some of them are in bad format. how to ignore those bad lines and continue to process the rest?

[bfzhao]

Given file with following content:

[]
{}
"hello"
12, 12
false
123

Note, the 4th line is in bad JSON format. jq just stops at this line after parsing error reported. I want jq to continue after emits a warning message.

Use raw input option with fromjson filter.

jq -R 'fromjson? | [your query here]'
