# jc.parsers.sfdisk

jc - JSON CLI output utility `sfdisk` command output parser

Supports the following `sfdisk` options:
- `-l`
- `-F`
- `-d`   (deprecated - only for older versions of util-linux)
- `-uM`  (deprecated - only for older versions of util-linux)
- `-uC`  (deprecated - only for older versions of util-linux)
- `-uS`  (deprecated - only for older versions of util-linux)
- `-uB`  (deprecated - only for older versions of util-linux)

Usage (cli):

# sfdisk -l | jc --sfdisk

or

# jc sfdisk -l

Usage (module):

import jc
result = jc.parse('sfdisk', sfdisk_command_output)

or

import jc.parsers.sfdisk
result = jc.parsers.sfdisk.parse(sfdisk_command_output)
