Jc / Output Pretty Json Via Magic Syntax
Output Pretty Json Via Magic Syntax
Outputs the result of the jc command in a pretty JSON format for ease of reading.
jc -p <ifconfig> jc -p <ifconfig> #!/bin/bash
# Output Pretty Json Via Magic Syntax
jc {{[-p|--pretty]}} {{ifconfig}} import subprocess
# Output Pretty Json Via Magic Syntax
# Make sure to replace <placeholders> with actual values
def run_command():
cmd = [
"jc",
"-p",
"<ifconfig>"
]
try:
print(f"Executing: {' '.join(cmd)}")
subprocess.run(cmd, check=True)
except subprocess.CalledProcessError as e:
print(f"Error: {e}")
except FileNotFoundError:
print("Error: jc not found. Please install it first.")

run_command() When To Use
When integrating system commands into automated scripts that require JSON output.
Pro Tip
Using '--pretty' may not handle nested structures well; verify output integrity after parsing.
Command Builder
Tune the command before you copy it
jc -p <ifconfig> Anatomy of Output
Understanding the result
{"interfaces": [{"name": "eth0", "inet": "192.168.1.2"}]} JSON Output Structure Displays interfaces as an array of objects with their respective attributes.
{"interfaces": [{"name": "wlan0", "inet": "10.0.0.5"}]} Multiple Interfaces Shows handling of additional interfaces.
{"global": {"tx_bytes": 12345678, "rx_bytes": 87654321}} Global Statistics Represents total transmitted and received bytes across interfaces.
Power User Variants
Optimized versions
jc -p ifconfig Directly format ifconfig output for better readability.
jc --pretty ifconfig | tee output.json Saves output to a file while printing it to stdout.
Troubleshooting
Common pitfalls
jc: command not found
Solution: Install jc: sudo apt-get install jc
Error: Unable to process input from ifconfig
Solution: Ensure ifconfig is installed and functional.
Invalid option: -p or --pretty
Solution: Check the jc documentation for supported options.
