我在变量名中有以下JSON它在containerDefinitions下的末尾TASK_DEFINTIION 有一个\r字符"image": "700707367057.dkr.ecr.us-east-1.amazonaws.com/php-demo:feature-feature01\r"

我TASK_DEFINITION_AFTER= 'echo $TASK_DEFINTIION | sed "s/\\r//g"'用来删除\r但似乎它正在删除所有隐藏的回车符，但没有删除作为常规字符可见的回车符。

任何帮助都会受到高度评价。

jq rtrimstr用于保持与 JSON 语法一致：

#!/usr/bin/bash

TASK_DEFINTIION="$(
  jq '.containerDefinitions[].image|=rtrimstr("\r")' <<<"$TASK_DEFINTIION"
)"

echo "$TASK_DEFINTIION"

man jq：

rtrimstr(str) 如果它以它结尾，则输出它的输入并删除给定的后缀字符串。

      jq ´[.[]|rtrimstr("foo")]´
         ["fo", "foo", "barfoo", "foobar", "foob"]
      => ["fo","","bar","foobar","foob"]

在您的命令中，第一个 \ 转义了第二个 \，因此sed只看到一个 \

你需要 ：

TASK_DEFINITION_AFTER="$(echo $TASK_DEFINTIION | sed "s/\\\\r//g")"

您可以使用jq替换键值：

jq '.containerDefinitions[].image="700707367057.dkr.ecr.us-east-1.amazonaws.com/php-demo:feature-feature01"' file.json

但不幸的是，jq不支持就地编辑，因此您必须先重定向到临时文件，然后用它替换原始文件，或者使用sponge更多 utils 包中的实用程序，如下所示：

jq '.containerDefinitions[].image="700707367057.dkr.ecr.us-east-1.amazonaws.com/php-demo:feature-feature01"' file.json|sponge file.json

用 删除的纯jq解决方案：\rgsub

jq '.containerDefinitions[].image|=gsub("[\r]"; "")' file.json|sponge file.json

输出样本：

  "placementConstraints": [],
  "cpu": "512",
