# JC
JSON CLI output utility
`jc` is used to JSONify the output of many standard linux cli tools for easier parsing in scripts. Parsers for `ls`, `ifconfig`, `ps`, `route`, and `netstat` are currently included and more can be added via modules.
`jc` is used to JSONify the output of many standard linux cli tools for easier parsing in scripts. See the **Parsers** section for supported commands.
This allows further command line processing of output with tools like `jq` simply by piping commands:

`jc` accepts piped input from `STDIN` and outputs a JSON representation of the previous command's output to `STDOUT`. The JSON output can be compact or pretty formatted.
Parsers:
### Parsers
- `--df` enables the `df` parser
- `--env` enables the `env` parser
- `--free` enables the `free` parser
- `--ifconfig` enables the `ifconfig` parser
- `--iptables` enables the `iptables` parser
- `--ls` enables the `ls` parser
- `--lsblk` enables the `lsblk` parser
- `--mount` enables the `mount` parser
- `--netstat` enables the `netstat` parser
- `--ps` enables the `ps` parser
- `--route` enables the `route` parser
- `--uname` enables the `uname -a` parser
Options:
### Options
- `-p` specifies whether to pretty format the JSON output
