将 json 中的 \r 替换为 shell

Question

我在变量名JSON下面有TASK_DEFINTIION 它在 containerDefinitions

下的 "image": "700707367057.dkr.ecr.us-east-1.amazonaws.com/php-demo:feature-feature01\r" 末尾有一个 \r 字符

我正在使用 TASK_DEFINITION_AFTER= 'echo $TASK_DEFINTIION | sed "s/\r//g"' 删除 \r 但似乎它正在删除所有隐藏的马车 return 但没有删除可见的作为常规字符。

如有任何帮助，我们将不胜感激。

Answer 1

在你的命令中，第一个 \ 转义了第二个 \，所以 sed 只看到一个 \

你需要：

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

Answer 2

使用 jq rtrimstr 以保持符合 JSON 语法：

#!/usr/bin/bash

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

echo "$TASK_DEFINTIION"

man jq:

rtrimstr(str) Outputs its input with the given suffix string removed, if it ends with it.
      jq ´[.[]|rtrimstr("foo")]´
         ["fo", "foo", "barfoo", "foobar", "foob"]
      => ["fo","","bar","foobar","foob"]

Answer 3

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，所以您必须先重定向到一个临时文件，然后用它替换您的原始文件，或者使用更多的 sponge 实用程序utils 包，像这样：

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

用 gsub 删除 \r 的纯 jq 解决方案：

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