blocks|key|1840010|text|在*nix上，您可以使用comm。问题的答案是：|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|1840011|comm+-1+-2+file1.sorted+file2.sorted+

On *nix, you can use <a href="http://www.ss64.com/bash/comm.html" rel="noreferrer">comm</a>. The answer to the question is:

<pre><code>comm -1 -2 file1.sorted file2.sorted 
# where file1 and file2 are sorted and piped into *.sorted
</code></pre>

Here's the full usage of <code>comm</code>:

<pre><code>comm [-1] [-2] [-3 ] file1 file2
-1 Suppress the output column of lines unique to file1.
-2 Suppress the output column of lines unique to file2.
-3 Suppress the output column of lines duplicated in file1 and file2. 
</code></pre>

Also note that it is important to sort the files before using comm, as mentioned in the man pages.

blocks|key|1840109|text|之前有人在这里问过：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1840110|您也可以尝试使用Perl+(credit+goes+here)：|offset|length|1840111|perl+-ne+'print+if+($seen{$_}+.=+@ARGV)+=~+/10$/'++file1+file2|code-block|syntax|javascript|1840112|entityMap|0|LINK|mutability|MUTABLE|url|http://www.cyberciti.biz/faq/command-to-display-lines-common-in-files/^0|0|L|9|0|0|0^^$0|@$1|2|3|4|5|6|7|S|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|T|8|@]|9|@$D|U|E|V|1|W]]|A|$]]|$1|F|3|G|5|H|7|X|8|@]|9|@]|A|$I|J]]|$1|K|3|-4|5|6|7|Y|8|@]|9|@]|A|$]]]|L|$M|$5|N|O|P|A|$Q|R]]]]

It was asked here before: <a href="https://stackoverflow.com/questions/373810/unix-command-to-find-lines-common-in-two-files">Unix command to find lines common in two files</a>
You could also try with Perl (credit <a href="http://www.cyberciti.biz/faq/command-to-display-lines-common-in-files/" rel="nofollow noreferrer">goes here</a>):
<pre><code>perl -ne 'print if ($seen{$_} .= @ARGV) =~ /10$/' file1 file2
</code></pre>

blocks|key|1840233|text|我刚从答案中学习了命令，但是我想添加一些额外的东西:如果文件没有排序，并且您不想接触原始文件，那么可以通过管道输出命令。这将使原始文件保持不变。它在Bash中可以工作，但我不能说其他shell。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1840234|comm+-1+-2+<(sort+file1)+<(sort+file2)|code-block|syntax|javascript|1840235|这可以扩展为比较命令输出，而不是文件：|1840236|comm+-1+-2+<(ls+/dir1+%7C+sort)+<(ls+/dir2+%7C+sort)|1840237|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

I just learned the <a href="https://linux.die.net/man/1/comm" rel="nofollow noreferrer">comm</a> command from the answers, but I wanted to add something extra: if the files are not sorted, and you don't want to touch the original files, you can pipe the output of the <a href="https://linux.die.net/man/1/sort" rel="nofollow noreferrer">sort</a> command. This leaves the original files intact. It works in Bash, but I can't say about other shells.
<pre><code>comm -1 -2 &lt;(sort file1) &lt;(sort file2)
</code></pre>
This can be extended to compare command output, instead of files:
<pre><code>comm -1 -2 &lt;(ls /dir1 | sort) &lt;(ls /dir2 | sort)
</code></pre>

Just for information, I made a little tool for Windows doing the same thing as &quot;grep -F -x -f file1 file2&quot; (As I haven't found anything equivalent to this command on Windows)
Here it is:
<a href="http://www.nerdzcore.com/?page=commonlines" rel="nofollow noreferrer">http://www.nerdzcore.com/?page=commonlines</a>
Usage is &quot;CommonLines inputFile1 inputFile2 outputFile&quot;
Source code is also available (GPL).

blocks|key|1840462|text|最简单的方法是：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1840463|awk+'NR==FNR{a[$1]%2B%2B;next}+a[$1]+'+file1+file2|code-block|syntax|javascript|1840464|不需要对文件进行排序。|1840465|entityMap^0|0|0|0^^$0|@$1|2|3|4|5|6|7|K|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|L|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|M|8|@]|9|@]|A|$]]|$1|I|3|-4|5|6|7|N|8|@]|9|@]|A|$]]]|J|$]]

The easiest way to do it is:
<pre><code>awk 'NR==FNR{a[$1]++;next} a[$1] ' file1 file2
</code></pre>
Files are not necessary to be sorted.

I have a series of text files for which I'd like to know the lines in common rather than the lines which are different between them. Command line Unix or Windows is fine.
File foo:
<pre><code>linux-vdso.so.1 =&gt; (0x00007fffccffe000)
libvlc.so.2 =&gt; /usr/lib/libvlc.so.2 (0x00007f0dc4b0b000)
libvlccore.so.0 =&gt; /usr/lib/libvlccore.so.0 (0x00007f0dc483f000)
libc.so.6 =&gt; /lib/libc.so.6 (0x00007f0dc44cd000)
</code></pre>
File bar:
<pre><code>libkdeui.so.5 =&gt; /usr/lib/libkdeui.so.5 (0x00007f716ae22000)
libkio.so.5 =&gt; /usr/lib/libkio.so.5 (0x00007f716a96d000)
linux-vdso.so.1 =&gt; (0x00007fffccffe000)
</code></pre>
So, given these two files above, the output of the desired utility would be akin to <code>file1:line_number, file2:line_number == matching text</code> (just a suggestion; I really don't care what the syntax is):
<pre><code>foo:1, bar:3 == linux-vdso.so.1 =&gt; (0x00007fffccffe000)
</code></pre>

How can I show lines in common (reverse diff)?

Windows

Unix

Perl

我有一系列的文本文件，我想知道它们的共同之处，而不是它们之间的不同之处。命令行Unix或Windows都可以。文件foolinux-vdso.so.1 =>  (0x00007fffccffe000)libvlc.so.2 => /usr/lib/libvlc.so.2 (0x00007f0dc4b0b000)libv...
