masscan-json2json

#!/bin/sh
#
# Converts `masscan`'s JSON output to JSON lines that can be
# parsed by `jq` or `python -m json.tool --json-lines`.
# masscan (1.0.4) outputs an array with a trailing comma, which is invalid.
# This basically breaks the array into its elements, one per line.
# 
# Example:
#   [
#   {...},
#   {...},
#   ]
# 
# to
# 
#   {...}
#   {...}
#
# Usage example:
#   cat masscan_output.json | ./masscan-json2json | jq -r .ip

cat - | sed -e '/^\[/d' -e '/^\]/d' -e 's/,$//'
