parse JSON and malipulate its object values
Clash Royale CLAN TAG#URR8PPP

I have a json file named xyz.json as follows
[
"annotations": [ "a" , "b" , "c" ],
"class": "image",
"filename": "vc00_02201.png"
,
"annotations": ,
"class": "image",
"filename": "vc00_02202.png"
"annotations": ,
"class": "image",
"filename": "vc00_02203.png"
,
"annotations": ,
"class": "image",
"filename": "vc00_02204.png"
]
I need to copy the object "annotations" from "filename": "vc00_02201.png"
to "annotations" of "filename": "vc00_02204.png" within the same xyz.json file using a shell script.
Expected output:
[
"annotations": [ "a" , "b" , "c" ],
"class": "image",
"filename": "vc00_02201.png"
,
"annotations": ,
"class": "image",
"filename": "vc00_02202.png"
"annotations": ,
"class": "image",
"filename": "vc00_02203.png"
,
"annotations": [ "a" , "b" , "c" ],
"class": "image",
"filename": "vc00_02204.png"
]

Does it have to be shell script? This would certainly be easier in a scripting language with JSON support (all of the major ones, including at least Perl, Python, and Ruby). Also, if it has to be shell, which external utilities can you use? Can you use something like
jq?– derobert
Jan 8 at 18:03
yes I can use jq and python script is also fine.
