Awk 替换两个单词之间的换行符

我有一个文本文件的输出，如下所示。我想把someItems数组的所有内容放在一行下面。因此，每一行都有一个新的someItems数组的内容。例如：

"someItems": [
{
  "someId": "MountSomers-showtime.com-ETTI0000000000000003-1452005472058",
  "source": "MountSomers",
  "sourceAssetId": "9",
  "title": "Pk_3",
  "ppp": "12",
  "expirationDate": "2016-01-06T14:51:12Z"
},    {
  "someId": "MountSomers-ericsson.com- ETTI0000000000000005-1452005472058",
  "source": "MountSomers",
  "sourceAssetId": "12",
  "title": "Pk_5",
  "ppp": "12",
  "expirationDate": "2016-01-06T14:51:12Z"
}  ]
"someItems": [
{
  "someId": "MountSomers-hbo.com-ETTI0000000000000002-1452005472058",
  "source": "MountSomers",
  "sourceAssetId": "7",
  "title": "Pk_2",
  "ppp": "12",
  "expirationDate": "2016-01-06T14:51:12Z"
},    {
  "someId": "MountSomers-showtime.com-ETTI0000000000000003-1452005472058",
  "source": "MountSomers",
  "sourceAssetId": "9",
  "title": "Pk_3",
  "ppp": "12",
  "expirationDate": "2016-01-06T14:51:12Z"
},    {
  "someId": "MountSomers-ericsson.com-ETTI0000000000000005-1452005472058",
  "source": "MountSomers",
  "sourceAssetId": "12",
  "title": "Pk_5",
  "ppp": "12",
  "expirationDate": "2016-01-06T14:51:12Z"
}  ]

将成为

"someItems": [ ..... ]
"someItems": [ ..... ] 

我有下面的

cat file | | awk '/^"someItems": [/{p=1}/^]/{p=0} {if(p)printf "%s",$0;else printf "%s%s\n",(NR==1?"":RS),$0}'

---

但它不符合我的要求

由于输入仅在外部级别包含方括号，因此解决方案非常简单：

awk '{gsub("\n","", $0)}1' RS=']\n' file

我正在使用

]\n

作为输入记录分隔符。这将为您提供

“someItems:…”

之间的整个部分，直到关闭

]

为止，作为

$0

gsub（）

只是替换换行符<代码>1打印（修改的）记录

---

您还可以使用

sed

：

sed '/\[/{:a;N;/]/!ba;s/\n//g}' file

我将在多行版本中对此进行解释：

script.sed：

#地址。匹配包含洞口的行[
/\[/{#块的开始
#定义标签“a”
：a
#读取新行并将其附加到模式缓冲区
N
#如果模式缓冲区不包含结束符]
#跳回标签“a”
/]/！巴
#出现右括号后，请更换所有换行符
#因为在这种情况下我们不会跳回“a”，这意味着我们将
#离开区块，开始新的循环。
s/\n//g
}#块端

---

打印不带尾随换行符的每一行。从第二个匹配项开始，在每个

“someItems”

之前放置一个前导换行符。在结尾处打印一条换行符以保持优雅。

awk解决方案简单明了+1.

$ awk '/^"someItems":/ && f { printf "\n" } { printf $0; f=1 } END { printf "\n" }' file.txt
"someItems": [{  "someId": "MountSomers-showtime.com-ETTI0000000000000003-1452005472058",  "source": "MountSomers",  "sourceAssetId": "9",  "title": "Pk_3",  "ppp": "12",  "expirationDate": "2016-01-06T14:51:12Z"},    {  "someId": "MountSomers-ericsson.com- ETTI0000000000000005-1452005472058",  "source": "MountSomers",  "sourceAssetId": "12",  "title": "Pk_5",  "ppp": "12",  "expirationDate": "2016-01-06T14:51:12Z"}  ]
