# JC
2019-10-17 13:04:34 -07:00
JSON CLI output utility
2019-10-15 15:06:09 -07:00
2019-10-22 11:17:21 -07:00
`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.

2019-10-18 09:57:10 -07:00
This allows further command line processing of output with tools like `jq` simply by piping commands:
```
2019-10-25 15:39:48 -07:00
$ ls -l /usr/bin | jc --ls | jq '.[] | select(.size|tonumber > 50000000)'
2019-10-18 09:57:10 -07:00
{
"filename": "emacs",
"flags": "-r-xr-xr-x",
2019-10-29 14:19:04 -07:00
"links": "1",
2019-10-18 09:57:10 -07:00
"owner": "root",
"group": "wheel",
2019-10-25 15:39:48 -07:00
"size": "117164432",
2019-10-18 09:57:10 -07:00
"date": "May 3 22:26"
}
```
2019-10-25 15:39:48 -07:00
The `jc` parsers can also be used as python modules. In this case the output will be a python dictionary instead of JSON:

The goal is to keep the resulting JSON as flat and simple as possible. Also, keys have been converted to lowercase and special characters are replaced whenever possible. Numbers are kept as strings because, depending on context or the output options, numbers can sometimes turn into strings. (e.g 'human readable' options)

```
2019-10-17 15:03:32 -07:00
`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.
