I want to do a very simple thing. I have two files as follows:
我想做一件非常简单的事情。我有两个文件如下:
FILE 1:
A s1 p1
B s2 p2
C s3 p3
FILE2:
B s4 p4
A s1 p1
C s6 p6
I want to extract first and third column from both file and print diff of that file. One easy way is to create intermediate files with cut -f1,3 of both files and do diff. Thats what exactly i want my output is. But i don't want to create intermediate file. Any simple one liner to do that.
我想从该文件的文件和打印差异中提取第一列和第三列。一种简单的方法是使用cut -f1,3创建两个文件的中间文件并执行diff。多数民众赞成我想要的输出是什么。但我不想创建中间文件。任何简单的衬垫都可以做到这一点。
One more thing, both the files are NOT sorted, so unable to use join directly.
还有一件事,两个文件都没有排序,所以无法直接使用join。

Try this:
diff <(cut -f1,3 file1) <(cut -f1,3 file2)
References:
Compare two files line by line and generate the difference in another file
逐行比较两个文件并在另一个文件中生成差异

使用[流程替换]
diff -y <( awk '{print $1,$3}' file1) <( awk '{print $1,$3}' file2 )
should do it. Note -y option with diff is for side-by-side o/p.
应该这样做。注意-y选项与diff是并排的o / p。
