Question

我在bash中有两个变量：

在第一个变量中，字段分隔符为（，）在第二个变量中，字段分隔符也是（，）

在名为VAR1的第一个变量中，我有：

Maria Debbie Annie,Chewbakka Zero,Yoda One,Vader 001

在名为VAR2的第二个变量中：

"number":"11112",Maria Debbie Annie
"number":"11113",Maria Debbie Annie Lisa
"number":"33464",Chewbakka Zero
"number":"22465",Chewbakka Zero Two
"number":"34534",Christine Ashley
"number":"45233",Yoda One
"number":"45233",Yoda One One
"number":"38472",Susanne Ann
"number":"99999",Vader 001
"number":"99991",Vader 001 001
"number":"99992",Vader 001 002

变量VAR3中所需的输出：

"number":"11112","number":"33464","number":"45233","number":"99999"

因此，基本上我需要将输出中的名称从第一个变量的顺序更改为"number":"somenumber"。还有非常相似的字符串也很重要，因此 Yoda One != Yoda One One也Chewbakka Zero不等于Chewbakka Zero Two。

VAR2包含的行数比列出的要多得多，我只是想表明脚本需要找到VAR1和VAR2之间的精确匹配项。感谢您的帮助。

检查一下。

> echo "$VAR1"
Maria Debbie Annie,Chewbakka Zero,Yoda One,Vader 001
> echo "$VAR2"
"number":"11112",Maria Debbie Annie
"number":"11113",Maria Debbie Annie Lisa
"number":"33464",Chewbakka Zero
"number":"22465",Chewbakka Zero Two
"number":"34534",Christine Ashley
"number":"45233",Yoda One
"number":"45233",Yoda One One
"number":"38472",Susanne Ann
"number":"99999",Vader 001
"number":"99991",Vader 001 001
"number":"99992",Vader 001 002
> export VAR1A=$(echo $VAR1| sed 's/,/$\|/g' | sed 's/$/\$/g')
> echo "$VAR1A"
Maria Debbie Annie$|Chewbakka Zero$|Yoda One$|Vader 001$
> echo "$VAR2"  | egrep "$VAR1A" | awk -F"," ' { printf("%s,",$1)} END { printf("\n") } ' | sed 's/.$//g'
"number":"11112","number":"33464","number":"45233","number":"99999"
