仅比较 File1 中的前 4 列（CSV 格式）与 File2 中的前 4 列并打印 File1 i 中的所有列

Question

我正在尝试比较两个 CSV 格式的文件

第一个文件是动态的，每天都会添加列， 在第二个文件上它只有 4 列（静态） 将 File1 上的前 4 列与 File2 上的 4 列进行比较，并打印 File1 中与 File2 匹配的所有列

例如：

代码

awk -F, 'NR==FNR{ arr[$2]=$1 $2 $3 $4; next } { print $0, (arr[$2]==$1 $2 $3 $4?"OK":"NOK") }' OFS=, File2 File1 

但它只匹配第一行。

Answer 1

我相信您的预期输出的第一行是错字？由于 Input_file2 的所有 4 个字段都没有进入 Input_file1。请您尝试关注一下。

awk 'BEGIN{FS=OFS=","}FNR==NR{a[$1,$2,$3,$4];next} (($1,$2,$3,$4) in a){print $0, "OK"}' Input_file2  Input_file1

说明：这里也为上述代码添加说明。

awk -F, '                ##Mentioning field separator as comma(,) here for all lines of Input_file(s).
BEGIN{                   ##Starting BEGIN section of awk program here.
  FS=OFS=","             ##Setting field separator and output field separator as comma(,) here.
}
FNR==NR{                 ##FNR==NR condition will be when 1st Input_file named Input_file2 is being read.
  a[$1,$2,$3,$4]         ##Creating an array named a whose index is $1,$2,$3,$4 fields of Input_file2 lines.
  next                   ##next will skip all further statements from here.
}                        ##Closing first condition block now.
(($1,$2,$3,$4) in a){    ##Checking condition if $1,$2,$3,$4 of Input_file1 are present in array a if yes then do following.
  print $0,"OK"          ##Printing current line with OFS and OK string here now.
}
' Input_file2  Input_file1   ##Mentioning Input_file name(s) Input_file2 and Input_file1 here.
