【问题描述】：
我已经用 jq 从 json 对象中读取了属性并将它们存储到变量中。
我现在想读取这些变量，并从本质上找到字符串中的一个单词并将其替换为一个全局 shell 变量。
我已经从我的 JSON 文件中设置了我的 json ID
# Set Json ID's
TARGET_ID=$(jq '.DefaultCacheBehavior.TargetOriginId' distconfig.json)
DOMAIN_NAME=$(jq '.Origins.Items[0].DomainName' distconfig.json)
ORIGIN_ID=$(jq '.Origins.Items[0].Id' distconfig.json)
echo "$TARGET_ID"
echo "$DOMAIN_NAME"
echo "$ORIGIN_ID"
这会返回
"S3-Website-stag4.example.io.s3-website.us-east-2.amazonaws.com"
"stag4.example.io.s3-website.us-east-2.amazonaws.com"
"S3-Website-stag4.example.io.s3-website.us-east-2.amazonaws.com"
我有我的位置 ID 变量，并想编写它来查找和替换这 3 个 ID 中的所有 stag4 引用。
然后我想将这 3 个 ID 写入初始 json 对象，或者创建它的临时版本。
例如，如果：
$DOMAIN_NAME是"stag4.example.io.s3-website.us-east-2.amazonaws.com"
我想基本上将其设置为：
$LOCATION_NAME="stag6"
DOMAIN_LOCATION="example.io"
"$DOMAIN_NAME=S3-Website-\$LOCATION_NAME\.example.io.s3-website.us-east-2.amazonaws.com"
"$TARGET_ID=\$LOCATION_NAME\.example.io.s3-website.us-east-2.amazonaws.com"
"$ORIGIN_ID=S3-Website-\$LOCATION_NAME\.example.io.s3-website.us-east-2.amazonaws.com"
然后将这 3 个写入临时或新的 json 文件，以便我可以运行我的 cloudformation 命令：
aws cloudfront create-distribution --distribution-config file://disttemp.json
我现在已经从初始 json 文件中构建了正确的变量，如下所示：
$LOCATION_NAME="stag6"
DOMAIN_LOCATION="example.io"
echo "Build New IDs"
TARGET_ID_BUILT="S3-Website-$LOCATION_NAME.$DOMAIN_LOCATION.s3-website.us-east-2.amazonaws.com"
DOMAIN_NAME_BUILT="$LOCATION_NAME.$DOMAIN_LOCATION.s3-website.us-east-2.amazonaws.com"
ORIGIN_ID_BUILT="S3-Website-$LOCATION_NAME.$DOMAIN_LOCATION.s3-website.us-east-2.amazonaws.com"
echo "$TARGET_ID_BUILT"
echo "$DOMAIN_NAME_BUILT"
echo "$ORIGIN_ID_BUILT"
如何用jq将这些变量写入json文件？

是的，我正在尝试使用建议的临时文件，我只是不确定如何执行“查找和替换”操作，即在新文件中设置新变量来代替我得到的位置初始文件中的旧变量
-
@oguzismail 添加了一个 sn-p，谢谢
-
@user3648969 见How to create a Minimal, Complete, and Verifiable example。您提供的示例是一个不完整的 JSON 值，并且它没有名为
DefaultCacheBehavior的键，而您的代码表明TARGET_ID是从那里检索到的。 -
@oguzismail 抱歉，我在对象底部放了一个省略号以表示它继续，我只是不想用完整的对象把帖子弄得乱七八糟。只要我知道查找和替换变量之一的函数，我就可以将其应用于不同的路径
