加入第一個字段的2個文件

Question

我想比較兩個文件file1 $ 1等於file2 $ 1並顯示輸出file1 $ 1 $ 2 $ 3 $ 4 $ 5 $ file2 $ 2 $ 5。並將file1 $ 5的差異 - 文件2 $ 5

輸入文件1.txt的

2,mona,KR,SIND,12:41:46.36 
3,JO,TM,SIND,18:31:56.36 
4,andrew,sind,13:43:23.12 
5,drew,sind,17:53:53.42 

輸入文件2.txt

5,raju,UP,NIND,11:51:56.46 
6,NAG,KR,SIND,12:41:46.36 
7,JO,TM,SIND,18:31:56.36

輸出：

Answer 1

隨着awk你會怎麼做：

$ awk 'NR==FNR{a[$1]=$0;next}$1 in a{print a[$1],$2,$5}' FS=, OFS=, f1 f2

4,andrew,sind,13:43:23.12,andrew, 
3,JO,TM,SIND,18:31:56.36,sandrew, 
2,mona,KR,SIND,12:41:46.36,xcandrew, 
1,raja,AP,NIND,14:51:56.46,cv,5:31:56.36 

如果你想然後通過管道排序，以sort輸出：

$ awk 'NR==FNR{a[$1]=$0;next}$1 in a{print a[$1],$2,$5}' FS=, OFS=, f1 f2 | sort 
1,raja,AP,NIND,14:51:56.46,cv,5:31:56.36 
2,mona,KR,SIND,12:41:46.36,xcandrew, 
3,JO,TM,SIND,18:31:56.36,sandrew, 
4,andrew,sind,13:43:23.12,andrew, 
5,drew,sind,17:53:53.42,raju,11:51:56.46 

使用替代join：

$ join -j1 -t, -o 1.1,1.2,1.3,1.4,1.5,2.2,2.5 <(sort f1) <(sort f2) 
1,raja,AP,NIND,14:51:56.46,cv,5:31:56.36 
2,mona,KR,SIND,12:41:46.36,xcandrew, 
3,JO,TM,SIND,18:31:56.36,sandrew, 
4,andrew,sind,13:43:23.12,,andrew, 
5,drew,sind,17:53:53.42,,raju,11:51:56.46
