我们说我在JSON中有一些文字:
{
"key1": "value1"
"key2": "value2"
"key3": "value3"
"key4": "value4"
"key5": "value5"
}
{
"key1": "value1"
"key2": "value2"
"key3": "value3"
"key4": "value4"
"key5": "value5"
}
我想要做的是找到" value1",但只打印" value5"。会有很多" value5"(s),但我只想打印它,如果前面是" value1" (这将是一个独特的字符串)。我无法使用grep -Ax & -Bx
由于我不想在之后匹配该行,而是想要打印该字符串。

示例文件:
cat t
{
"key1": "value1"
"key2": "value2"
"key3": "value3"
"key4": "value4"
"key5": "value5"
}
{
"key1": "value6"
"key2": "value2"
"key3": "value3"
"key4": "value4"
"key5": "value5"
}
如果key5
key1=value6
打印数据
awk '/key1/ && /value6/ {f=1} f && /key5/ {print $NF;f=0}'
"value5"
