如何将bash数组格式化为JSON数组

问题描述：

我有一个bash数组

X=("hello world" "goodnight moon")

我想变成一个json数组

That I want to turn into a json array

["hello world", "goodnight moon"]

是否有一种好方法可以将其转换为json字符串数组，而无需遍历子shell中的键?

Is there a good way for me to turn this into a json array of strings without looping over the keys in a subshell?

(for x in "${X[@]}"; do; echo $x | sed 's|.*|"&"|'; done) | jq -s '.'

这显然行不通

echo "${X[@]}" | jq -s -R '.'

答

您可以执行以下操作:

X=("hello world" "goodnight moon")
printf '%s\n' "${X[@]}" | jq -R . | jq -s .

[
  "hello world",
  "goodnight moon"
]
