文件的差异，从第N行 [英] Difference of files from Nth line

问题描述

我想获得的两个文本文件的差异。然而，第一行可以随时改变。出于这个原因，我是从一个python执行此：

I am trying to get the difference of two text files. However, the first line can always change. For this reason I was executing this from a python:

tail -n +2 file1
tail -n +2 file2

然后我比较的结果从输出相匹配。

Then to compare I match the results from the outputs.

不过，我想用 AWK 或 SED 如果可能的话。

However, I would like to use awk or sed if possible.

我发现迄今：

awk 'NR == FNR { A[$0]=3; next } !A[$0]' file2 file1

但这从第一行相比较。

but this compares from the first line.

我怎样才能从第二个差异比较行？

How can I diff from the second line?

推荐答案

您可以使用差异与进程替换：

diff <(tail -n +2 file1) <(tail -n +2 file2)
