Parse property from json file
Hello All,


Greetings..


I have a json file that I need to pase its URLs and other values.
The match should start with "notifications" and output URLs and settings values.


I tried with python or awk but hardly could get URLs only. Or whole URLs from full json file. Could not match with property notifications.



I prefer awk, sed, grep, perl. For macOS using bash shell.




Code:
"notifications":{"https://www.test.com:80,*":{"last_modified":"13219862418447583","setting":1},"https://www.example.com:443,*":{"last_modified":"13219862407099344","setting":1},"https://123abc.io:443,*":{"last_modified":"13219957709135648","setting":2},"https://www.facebook.com:443,*":{"last_modified":"13219934734073706","setting":2},"http://www.youtube.com:443,*":{"last_modified":"13219862410929224","setting":1}}

The output would be something like below (full URL/ short URL & settings)

Code:
https://www.test.com, setting:1
https://www.example.com, setting:1
https://www.abc123.io, setting:2
https://www.facebook.com, setting:2
http://www.youtube.com, setting:1

targetctl

targetctl(8)						      System Manager's Manual						      targetctl(8)

NAME

       targetctl - Save and restore configuration of kernel target

DESCRIPTION

       targetctl  is  a  low-level script to save and restore the configuration of the LIO kernel target, to and from a file in json format. It is
       not normally meant to be used by end-users directly, but by system init frameworks, or advanced end-users who are generating the configura-
       tion file themselves and need a way to load the configuration without relying on the targetcli configuration shell.

USAGE

       targetctl must be invoked as root. Exit status will be 0 if successful, or nonzero if an error was encountered.

       targetctl save [config-file]

       Saves  the  current configuration of the kernel target to a file in json format. Since the file may contain cleartext passwords, the file's
       permissions will be set to only allow root access. If config-file is not supplied, targetctl will use the default file location,  /etc/tar-
       get/saveconfig.json.

       targetctl restore [config-file]

       Removes	any  existing configuration and replaces it with the configuration described in the file. See saveconfig.json(5) for more details.
       If parts of the configuration could not be restored, those parts will be noted in the error output, and the rest of the configuration  will
       still be applied.

       targetctl clear

       Removes any existing configuration from the running kernel target.

       targetctl --help

       Displays usage information.

SEE ALSO

       targetcli(8), targetd(8), saveconfig.json(5)

FILES

       /etc/target/saveconfig.json

       /sys/kernel/config/target
