JC

JSON CLI output utility v0.1

jc is used to JSONify the output of many standard linux cli tools for easier parsing in scripts. Parsers for ls, ifconfig, and netstat are currently included and more can be added via modules.

Usage

jc accepts piped input from STDIN and outputs a JSON representation of the previous command to STDOUT. The JSON output can be compact or pretty formatted.

The first argument is required and identifies the command that is piping output to jc input. For example:

• --ls enables the ls parser
• --ifconfig enables the ifconfig parser
• --netstat enables the netstat parser

The second -p argument is optional and specifies whether to pretty format the JSON output.

Examples

$ ls -l /bin | jc --ls -p
