【问题描述】：
我正在编写一个 bash 脚本，并且很难从匹配的子字符串中提取值。 我无法共享 curl 命令，因为它包含敏感信息，但会更新我遇到问题的 i 值（1）（更新为模拟真实值）。 jq 给出解析错误
curl -s -g "$line" | jq -c '.allBuilds[]' | while read i; do
job_name=$(echo "$i" | jq .fullDisplayName | tr -d '»' | tr -s " " | sed 's/ /,/g' | tr -d '"')
done
预期输出
Hello,Java,World,master,#47
我得到了大多数 i 值的预期输出，但出现了一些错误
下面是样本 i 值。

我正在尝试提取 fullDisplayName 值，并且尝试了一些选项，例如
printf '%s\n' "$i" | grep fullDisplayName
printf '%s\n' 在 shell 中尝试时以新行输出输出，但在脚本中其行为不同
{}
{}
{}]
fullDisplayName:Hello » Java » World » master #25
id:25
number:25
timestamp:1575582153372
【问题讨论】：
-
你为什么要 grep 为
fullDisplayName并期望得到输出"Hello»Java»World»master#22","id":"22","number":22,"timestamp":1574705541773显然不包含你 grep 的字符串fullDisplayName？ -
你能发布
curl命令的输出吗？ -
每个
""对中的"s 在curl -s -g ""$line""中的$line周围相互抵消，所以什么都不做。""$line""与$line完全相同，因为它两侧的""只是一个空字符串。我认为/希望你的意思是"$line"在两边都有单独的双引号（就像你在脚本后面对"$i"所做的那样）所以你引用$line而不是在两边多余地放置一个空字符串它。 -
@EdMorton 编辑了我的帖子（一直在尝试不同的选项）。
