我需要得到以下结果。

cat sample.txt

"killPointsDelta":-6.18067741,"killStreaks":0,"kills":1
"killPointsDelta":-6.18067741,"killStreaks":0,"kills":3
"killPointsDelta":-6.18067741,"killStreaks":0,"kills":5
"killPointsDelta":-6.18067741,"killStreaks":0,"kills":0


perl -ne 'print "$&\n" if /"kills":\K[^,}]+/' sample.txt

正确的预期结果：

1
3
5
0

到目前为止，一切都很好。但是问题是文件包含段落而不是行。
