JSON中有很多结构，您在尝试时忽略了这些结构。不过，您可能正在使用旧版本的
jqjq:error（在tmp.json:6）：无法用字符串“sids”索引数组，而不是核心转储。Hi@chepner！我不太熟悉json
，但我已经认识到了文件的复杂树结构。@arnpry:jq——原始输出.data[]\124;.meta“\（.sids）\（.ll）\（.state）\（.name）”
，给出了值，但是我没有足够的知识来整平数组。如果任何程序转储了它的核心，而你能够复制它，那么这个程序就做错了，而不是你。您应该在jq
1.5中不发生内核转储时向上游报告错误；如果有一个bug，它已经被修复了。这看起来就像我正在尝试做的！但是得到以下错误：“jq:error:syntax error，意外的无效字符（unixshell引用问题？）在第1行：jq:1编译错误”我真的不相信这一点。你确定你复制的命令是正确的吗？哇！我使用记事本++创建了该文件，当我保存该文件时，EOL转换设置为Windows（添加额外的换行符），而不是Unix。与@csv
@CharlesDuffy True相比，使用join（“，”
处理角点情况较差。但是，join（“，”）
对于非拐角的情况是很好的，因为您可以轻松地通过管道连接到awk-F，
。但是是的，在一个健壮的脚本中，我会使用@csv
