parse JSON and malipulate its object values
3
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"
}
]

this is also achievable via jtc in one line:
bash $ cat xyz.json | jtc -w'<vc00_02204.png>[-1][annotations]' -eu jtc -w'<vc00_02201.png>[-1][annotations]' xyz.json ;

Of course, it could have been done via referencing direct members of array, like:
bash $ cat xyz.json | jtc -w'[3][annotations]' -eu jtc -w'[0][annotations]' xyz.json ;
but then whole point of cross-referencing by filename would be moot.
