Question

我正在尝试比较CSV格式的两个文件

第一个文件是动态的，每天将添加列，在第二个文件上，它只有4列（静态）比较File1的前4列与File2的4列，并打印File1中与File2匹配的所有列

Ex：

文件1

AIXTSM1,VHOST,ASMET084-T,DAILY_1800_VM_SDC-CTL-PROD3,COMP,COMP,COMP

File2

AIXTSM1,VHOST,10.199.114.72,DAILY_1800_VM_SDC-CTL-PROD
AIXTSM1,VHOST,ADMET007,DAILY_1800_VM_SDC-CTL-PROD3
AIXTSM2,VHOST,ADMET014,DAILY_1900_VM_UDC-CTL-PROD
AIXTSM1,VHOST,AGGREGATE,DAILY_2200_VM_SDC-CTL-PROD5

结果

AIXTSM1,VHOST,10.199.114.72,DAILY_1800_VM_SDC-CTL-PROD3,COMP,COMP,COMP,OK
AIXTSM1,VHOST,ADMET007,DAILY_1800_VM_SDC-CTL-PROD3,COMP,COMP,COMP,OK
AIXTSM2,VHOST,ADMET014,DAILY_1900_VM_UDC-CTL-PROD,COMP,COMP,COMP,OK
AIXTSM1,VHOST,AGGREGATE,DAILY_2200_VM_SDC-CTL-PROD5,COMP,COMP,COMP,OK

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

但是它仅匹配第一行。

Answer 1

我相信您预期输出的第一行是错字？由于Input_file2的所有4个字段都不在Input_file1中。您能不能试一下。

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： 也在此处添加了上述代码的说明。

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.

仅将File1（CSV格式）中的前4列与File2中的前4列进行比较，并打印File1中的所有列i
