## Usage
```
jc [parser] [options]
```
`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.
The first argument is required and identifies the command that is piping output to `jc` input. For example:
Parsers:
- `--ls` enables the `ls` parser
- `--ifconfig` enables the `ifconfig` parser
- `--netstat` enables the `netstat` parser
- `--ps` enables the `ps` parser
- `--route` enables the `route` parser
The second `-p` argument is optional and specifies whether to pretty format the JSON output.
Options:
- `-p` specifies whether to pretty format the JSON output
