使用UNIX命令行工具将JSON拆分为多行

Question

我们有一个JSON文件，它需要多行而不是单行，如下所示，

{this is the first block},{this is the second block, really},{this is the third you're kidding:no}

我们希望它是这样的，这样它就可以被馈送到一个外部程序中读取而不会出现问题，

{this is the first block}
{this is the second block, really}
{this is the third you're kidding:no}

我不是awk、sed、cut等简单文本处理工具的专家，但我确实尝试了一段时间，但没有成功。

cat test.json | sed 's/},/n/g'
{this is the first block
{this is the second block, really
{this is the third you're kidding:no}

最好的方法是什么？

Answer 1

因为它不是JSON，您只想拆分：

input_file

{this is the first block},{this is the second block, really},{this is the third you're kidding:no}

sed 's/},/}n/g' input_file

output

{this is the first block}
{this is the second block, really}
{this is the third you're kidding:no}

Answer 2

Awk替代方案：

awk 'BEGIN { RS="(,?{)|(},?)" } /[[:alnum:]]/ { print $0="{"$0"}" }' file

将记录分隔符设置为一个或多个逗号和｛或｝以及一个或更多个逗号。然后，当遇到字母数字字符串时，在字符串前面加前缀{，追加}并打印
