# jc.parsers.netstat

jc - JSON Convert `netstat` command output parser

Caveats:
- Use of multiple `l` options is not supported on OSX (e.g. `netstat -rlll`)
- Use of the `A` option is not supported on OSX when using the `r` option
  (e.g. `netstat -rA`)

Usage (cli):

    $ netstat | jc --netstat

or

    $ jc netstat

Usage (module):

    import jc
    result = jc.parse('netstat', netstat_command_output)
