如何将csv中的四列与awk进行比较？

Question

这是How to compare two columns of two csv files with awk?的后续问题。

我有两个 csv 文件需要与一列进行比较。

我的member.csv 文件如下所示：

ID|lastName|firstName|pubID
01|Lastname01|Firstname01|pubID01
02|Lastname02|Firstname02|pubID02
03|Lastname03|Firstname03|pubID03

第二个文件check-ID.csv 看起来像：

Lastname01|Name01|pubID01|Hash01
Lastname02|Name02|pubID02|Hash02a
LastnAme0X|Name03|pubID03|Hash03
Lastname04|Name04|pubID04|Hash04
Lastname02b|Name02|pubID02|Hash02b
Lastname01|Name01|pubID01|Hash01b

--> Lastname04 不在我的member.csv 中！

我想要检查check-ID.csv 第一列的值是否等于member.csv 中第二列的值，或者check-ID.csv 第四列的值是否等于第三列的值在member.csv

我的尝试是

awk 'BEGIN{  FS="|"} FNR==NR{  a[$2]; b[$4]; next }($1 in a  || $3 in b) ' member.csv check-ID.csv  | sort -t'|' -k1

但显然我没有得到正确的条件。

我希望得到过滤和排序的输出，因此只有成员会像这样列出：

Lastname01|Name01|pubID01|Hash01
Lastname01|Name01|pubID01|Hash01b
Lastname02|Name02|pubID02|Hash02a
Lastname02b|Name02|pubID02|Hash02b
LastnAme0X|Name03|pubID03|Hash03

任何帮助表示赞赏！

您能否尝试仅使用所示示例进行跟踪、编写和测试。

awk '
BEGIN{
  FS="|"
}
{  gsub(/\r/,"")  }
FNR==NR{
  a[$2]
  b[$4]
  next
}
($1 in a) || ($3 in b)
' members.csv  check-ID.csv |
sort -t'|' -k1

说明：为上述添加详细说明。

awk '                              ##Starting awk program from here.
BEGIN{                             ##Starting BEGIN section of this program from here.
  FS="|"                           ##Setting field separator as | here.
}
{  gsub(/\r/,"")  }                ##Globally substituting all control M characters in all lines.
FNR==NR{                           ##Checking condition if FNR==NR which will be TRUE when members.csv is being read.
  a[$2]                            ##Creating array a with index of 2nd field.
  b[$4]                            ##Creating array b with index of 4th field here.
  next                             ##next will skip all further statements from here.
}
($1 in a) || ($3 in b)             ##For check-ID.csv Input_file checking condition if either 1st field is present in a OR 3rd field is present in b then print that line.
' members.csv  check-ID.csv |      ##Mentioning Input_file names here.
sort -t'|' -k1                     ##Sending output of awk code to sort command and sorting it by first field with setting field separator as | for all lines.
