jc

JC Cheatsheet

JSONifies the output of many CLI tools and file-types for easier parsing in scripts.

Basic Usage

command | jc --parser          # Pipe output
jc command                    # Magic syntax
jc --help                     # List all parsers
jc --help --parser            # Parser docs

Examples

dig example.com | jc --dig | jq '.answer[].data'
ps aux | jc --ps
ifconfig | jc --ifconfig

Parsers

Options

Slicing

Skip lines: START:STOP syntax

cat file.txt | jc 1:-1 --parser  # Skip first/last lines

Slurp Mode

For multi-line parsers: --slurp outputs array

cat ips.txt | jc --slurp --ip-address

Python Library

import jc

# Parse command output
data = jc.parse('dig', output_string)

# Or parse directly
data = jc.parsers.dig.parse(output_string)

Tips

• Magic syntax: jc command auto-detects parser
• Use jq for processing: jc cmd | jq '.field'
• --slurp for multiple items per file
• Streaming parsers for large outputs
• Python lib returns dict/list, not JSON
