awk根據鍵值匹配併合並兩個文件

我有兩個文件，其中$3,$4 = $3,$2。awk根據鍵值匹配併合並兩個文件

文件1：

1211,A2,ittp,1,IPSG,a2,PA,3000,3000 
1311,A4,iztv,1,IPSG,a4,PA,240,250 
1411,B4,iztq,0,IPSG,b4,PA,230,250

文件2：

TP,0,nttp,0.865556,0.866667 
TP,1,ittp,50.7956,50.65 
TP,1,iztv,5.42444,13.8467 
TP,0,iztq,645.194,490.609

我想合併這些文件並打印新的文件一樣，如果file1 $3,$4 = file2 $3,$2然後打印合並文件中像

TP,1211,A2,ittp,1,IPSG,a2,PA,3000,3000,0.865556,0.866667 
TP,1311,A4,iztv,1,IPSG,a4,PA,240,250,50.7956,50.65 
TP,1411,B4,iztq,0,IPSG,b4,PA,230,250,5.42444,13.8467

兩個文件是CSV文件。

我嘗試使用awk但我沒有得到所需的輸出。它只打印file1。

$ awk -F, 'NR==FNR{a[$3,$4]=$3$2;next}{print $1, $2, $3, $4, $5, $6, $7, $8, $9, $10 a[$1] }' OFS=, 1.csv 2.csv

當你正在閱讀的第一個文件，你需要在'a [$ 3，$ 4]'中存儲'$ 0'。當你讀第二個文件時，你需要查找'a [$ 3，$ 2]'從第一個文件中獲得匹配的行，然後將它與當前行結合並打印出來。 – Barmar

不幸的是，'join'不適合你，因爲它只能匹配一個字段上的文件，而不是兩個。 – Barmar

awk -F, 'BEGIN {OFS=",";} 
     NR == FNR {a[$3,$4] = $0;} 
     NR != FNR && a[$3,$2] {print $1, a[$3,$2], $4, $5;}' 1.csv 2.csv

一種方式與awk：

awk 'NR==FNR{a[$4,$3]=$0;next}($2,$3) in a{print $1,a[$2,$3],$4,$5}' FS=, OFS=, f1 f2 
TP,1211,A2,ittp,1,IPSG,a2,PA,3000,3000,50.7956,50.65 
TP,1311,A4,iztv,1,IPSG,a4,PA,240,250,5.42444,13.8467 
TP,1411,B4,iztq,0,IPSG,b4,PA,230,250,645.194,490.609

使用加入如果I1和I2是輸入文件

cat i1.txt | awk -F',' '{print $3 "-" $4 "," $1 "," $2 "," $5 "," $6 "," $7 "," $8 "," $9}' | sort > s1.txt 
cat i2.txt | awk -F',' '{print $3 "-" $2 "," $1 "," $4 "," $5 }' | sort > s2.txt 
join -t',' s1.txt s2.txt | tr '-' ',' > t12.txt 
cat t12.txt | awk -F ',' '{print $10 "," $3 "," $4 "," $1 "," $2 "," $5 "," $6 "," $7 "," $8 "," $9 "," $11 "," $12 }'
