Split JSON into multiple files

Question

I have json file exported from mongodb which looks like:

{\"_id\":\"99919\",\"city\":\"THORNE BAY\"}
{\"_id\":\"99921\",\"city\":\"CRAIG\"}
{\"_id\":\"99922\         


        

Answer 1

Assuming you don't care about the exact filenames, if you want to split input into multiple files, just use split.

jq -c . < cities.json | split -l 1 --additional-suffix=.json - .chunks/cities_

Answer 2

In general to split any text file into separate files per-line using any awk on any UNIX system is simply:

awk '{close(f); f=".chunks/cities_"NR".json"; print > f}' cities.json
