我想将 awk 命令结果添加到 csv 文件中每行的末尾

我有如下文件：

输入文件.csv：

"Input_File:",AB-ABCDE.20220128.02064600,,,,
"Date_Time Received:","1-28-22 3:47",,,,
1, abc, xyz,pq,11
2, def, xyz,rs,22
3, ghi, xyz,tu,33
4, jkl, xyz,vw,44
5, mno, xyz,xy,55

输出文件.csv：

1, abc, xyz,pq,11,AB-ABCDE.20220128.02064600,1-28-22 3:47
2, def, xyz,rs,22,AB-ABCDE.20220128.02064600,1-28-22 3:47
3, ghi, xyz,tu,33,AB-ABCDE.20220128.02064600,1-28-22 3:47
4, jkl, xyz,vw,44,AB-ABCDE.20220128.02064600,1-28-22 3:47
5, mno, xyz,xy,55,AB-ABCDE.20220128.02064600,1-28-22 3:47

我从命令获取文件名和日期时间awk并存储如下：

file_name=`awk -F',' 'NR==1{print $2}' InputFile.csv`
date_time=`awk -F',' 'NR==2{print $2}' InputFile.csv`

我需要的是将捕获的 file_name 和 date_time 添加为每行的最后 2 列。

请帮我实现这个输出格式。

答案1

$ awk -F'"?,"?' -v OFS=',' 'NR<3{a[NR]=$2; next} {print $0, a[1], a[2]}' InputFile.csv
1, abc, xyz,pq,11,AB-ABCDE.20220128.02064600,1-28-22 3:47
2, def, xyz,rs,22,AB-ABCDE.20220128.02064600,1-28-22 3:47
3, ghi, xyz,tu,33,AB-ABCDE.20220128.02064600,1-28-22 3:47
4, jkl, xyz,vw,44,AB-ABCDE.20220128.02064600,1-28-22 3:47
5, mno, xyz,xy,55,AB-ABCDE.20220128.02064600,1-28-22 3:47

如果有人想打高尔夫球（受到现已删除的评论的启发），我们不需要删除 s "：

$ awk -F, '{a[NR]=$2} NR>2{print $0,a[1],a[2]}' OFS=, InputFile.csv
1, abc, xyz,pq,11,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
2, def, xyz,rs,22,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
3, ghi, xyz,tu,33,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
4, jkl, xyz,vw,44,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
5, mno, xyz,xy,55,AB-ABCDE.20220128.02064600,"1-28-22 3:47"

答案2

啊啊，这两行有区别。尝试

awk -F, 'NR==1 {FN = $2} NR==2 {DT = $2} NR>2{print $0, FN, DT}' OFS=, InputFile.csv
1, abc, xyz,pq,11,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
2, def, xyz,rs,22,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
3, ghi, xyz,tu,33,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
4, jkl, xyz,vw,44,AB-ABCDE.20220128.02064600,"1-28-22 3:47"
5, mno, xyz,xy,55,AB-ABCDE.20220128.02064600,"1-28-22 3:47"

答案3

您不需要将前两行的值捕获到 shell 变量中，因为awk它将为您完成所有工作。

awk -F, '
    BEGIN { OFS=FS }                                       # Output separator is same as input separator
    NR==1 { inputFile=$2 }                                 # Input File
    NR==2 { dtReceived=$2; gsub("\"", "", dtReceived) }    # Date Received, without surrounding double quotes
    NR>2 { print $0, inputFile, dtReceived }               # Copy through every line appending two new fields
' InputFile.csv > OutputFile.csv

在这里，我们有一个四行awk程序。您可以将所有内容放在一行中，但#如果这样做，请删除注释部分。但是，请考虑当您在几周（或几个月）后再次阅读时，哪一个更具可读性。

awk -F, 'BEGIN{OFS=FS} NR==1{inputFile=$2} NR==2{dtReceived=$2;gsub("\"","",dtReceived)} NR>2{print $0,inputFile,dtReceived}' InputFile.csv > OutputFile.csv

请注意，如果这是 CSV 文件，则无需删除双引号。但由于您想要的输出文件省略了它们，我也在这里删除了它们。

输出

1, abc, xyz,pq,11,AB-ABCDE.20220128.02064600,1-28-22 3:47
2, def, xyz,rs,22,AB-ABCDE.20220128.02064600,1-28-22 3:47
3, ghi, xyz,tu,33,AB-ABCDE.20220128.02064600,1-28-22 3:47
4, jkl, xyz,vw,44,AB-ABCDE.20220128.02064600,1-28-22 3:47
5, mno, xyz,xy,55,AB-ABCDE.20220128.02064600,1-28-22 3:47

答案4

Python

#!/usr/bin/python
k=open('filename','r')
fin_lines=k.readlines()
firslin=fin_lines[0].strip().split(':')[-1]
firsli_conte=firslin.replace('"','').replace(",","")
secondlin=fin_lines[1].strip().split(",")[1].replace('"','')
for test in fin_lines[2:]:
    print test.strip()+","+firsli_conte+","+secondlin






firs=$(awk -F ":" 'NR==1{gsub(/[",]/,"",$NF);print $NF}' filename )

sec=$(awk -F ":" 'NR==2{gsub(/[",]/,"",$2);gsub(/[",]/,"",$3);print $2":"$3}' filename )

awk -v firs="$firs" -v sec="$sec" 'NR>2{print $0","firs","sec}' filename

output
1, abc, xyz,pq,11,AB-ABCDE.20220128.02064600,1-28-22 3:47
2, def, xyz,rs,22,AB-ABCDE.20220128.02064600,1-28-22 3:47
3, ghi, xyz,tu,33,AB-ABCDE.20220128.02064600,1-28-22 3:47
4, jkl, xyz,vw,44,AB-ABCDE.20220128.02064600,1-28-22 3:47
5, mno, xyz,xy,55,AB-ABCDE.20220128.02064600,1-28-22 3:47
