文件不一定具有相同的行数（行）。现在，我想比较这两个文件，并找出它们之间是否有任何共同的第三列和每个文件中第1列的相应数字：
Example Output(randomly doing):
FileA FileB Data
290704 283811 000000000001111111111111110100001110000000000000101000011000000000100001100101110010000000000000000000000000000000000000000001
我已经使用follwoing命令生成了这些文件：
sort result.txt | uniq -c | sort -nr > File1.txt
现在我不确定如何找到共性。 unix“comm”对我不起作用。我想我可能需要使用“awk”或Python。但欢迎任何建议。
PS：这不是硬问题

在awk中。这是一个awk经典，足以学习语言的理由，是通向更好shell的途径：
onTouch()说明：
Square编辑：如果您有多个文件且可能有多次点击：
首先，更多测试数据（三个文件中的每个文件中有一个唯一记录，两个文件中有一个中继记录，三个文件中有一个）：
$ awk 'NR==FNR{a[$3]=$1;next}$3 in a{print $1, a[$3], $3}' f1 f2
1487 224885 000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000000
然后代码（这不是经典，不。这只是一个致敬）：
NR==FNR{ # process first file (the smaller)
a[$3]=$1 # hash to a using $3 as key
next # skip to next record
}
$3 in a{ # when a match is found processing the second file
print $1, a[$3], $3 # output in desired order
}
' f1 f2 # smaller file first as it is hashed to memory
请注意，所有yor数据都将存储到内存中，因此需要足够的内存。

我会使用sqlite数据库来解决这个问题，它非常容易学习，一旦你掌握了基础知识，它将解决你将面临的其他方法遇到的许多问题
下载sqlite浏览器即可参加Coursera或Udacity的在线课程
对于您的问题，它可以像
一样简单CREATE TABLE newtable AS SELECT column1.file1
FROM column3.file1
JOIN column3.file2
ON column3.file1=column3.file2
