Pipe Curl Output with Grep ending o Txt File in Ruby - ruby

Question

im encountering problems using curl within ruby. I want to run a ruby script and it should store a JSON type object like this
{
"remote": [
{"name": "cast-1",
"id": 1212
},
{"name": "cast-1",
"id": 1214
},
{"name": "home-11",
"id": 3212
},
{"name": "cast-3",
"id": 3212
},
{"name": "cast-3",
"id": 3213
},
{"name": "cast-4",
"id": 4211
}
]
}
in a text file. I mapped and grepped the curl input to get the desired entries.
Now when i run the script, my txt file pops out empty.
example of what i tried
#ruby
`curl -m 10 -s -H '[...]' "https://example_with_json_file.com" | jq -r .remote | group_by(.name) | map({ (.[0].name): map(.id) }) | "\(.[])" | grep '3\|4\|11' > file.txt`
foo = []
File.open(file.txt) do |file|
foo = file.readlines
end
[...]
running the above input in my temrinal works. I tried using Kernel.system order system within my ruby example. Nothing worked.
How can i pipe this output into a txt file
{"cast-3":[3212,3213]}
{"cast-4":[4211]}
{"home-11":[3212]}
Or in general, is it possible to run the curl input in a single line, that is executable using ruby?

Always it's better to do stuff in one language. Like:
response = HTTParty.get('https://path/to/json')
JSON.parse(response)
...
If you want mix it with Bash, try:
bar = `curl -m 10 -s -H '[...]' "https://example_with_json_file.com" | jq -r .remote | group_by(.name) | map({ (.[0].name): map(.id) }) | "\(.[])" | grep '3\|4\|11'`
foo = bar.split(/\n/)
File.write('/path/to/file', bar)
