根据 diff 输出打印 linux 文件中的特定行

发布于 2024-12-22 16:47:21 字数 1679 浏览 1 评论 0原文

我正在一个测试台上对一些硬件进行建模。每行都充当一个测试用例。我有以下内容：

文件输入 -->我的模型 --> 文件输出

我还有一个我的输出必须匹配的文件引用。

在开发过程中，输出和参考之间存在许多不匹配的情况。我需要知道不同的行号，然后将这些行从 File-In 复制到 File-In-bugs 因此，我可以使用有问题的线路运行 MyModel，以便更快地进行调试。

[编辑] 我的文件输入示例

（实际工作负载有数百万行）

输出

参考文件与正确的输出相同，但错误可能会导致更改一个或多个十六进制字符。在存在错误的行中，应将 File-In 复制到新文件 File-In-bugs。我希望这能让问题更加清楚。

到目前为止我所做的并不多。我认为linux管道很有用。

原文

I am working on a test bench to model some hardware. Each line acts as a test-case. I have the following:

File-In --> MyModel --> File-out

I also have a File-reference that my output must match.

When in development, many mismatches exist between the output and the reference. I need to know the line numbers that differ, then copy those lines from File-In to File-In-bugs
So I can run MyModel with the buggy lines for quicker debugging.

[Edit] Example for my files

INPUT (Actual workloads have millions of lines)

14088FF3FCFF3FCFF3FCFF3FCFF3FCFF 00000
18088FF3FCFF3FCFF3FCFF3FCFF3FCFF 00000

REFERENCE files are identical to the correct output, but bugs may lead to change one ore more hex characters. At lines with bugs, the File-In shall be copied to a new file, File-In-bugs. I hope this makes the problem more clear.

What I did so far is not much. I think linux pipes can be useful.

diff --old-line-format '%L' --new-line-format '' --unchanged-line-format ''  File-out File-Reference

将生成仅显示只能在 File-out 中找到的行的输出，但不会提供行号。如果您确实需要在输出中使用它：

    diff --old-line-format '%L' --new-line-format '' --unchanged-line-format ''  <(nl File-out) <(nl File-Reference)

应该可以。

更新：回答下面的评论：

diff --old-line-format '%L' \
     --new-line-format '' \
     --unchanged-line-format '' \
     <(nl File-out) <(nl File-ref) | \
awk '{print $1 "p"}' > BUGLINEPRINTER.sed && \
sed -n -f BUGLINEPRINTER.sed File-In > File-In-bugs

会做你想做的事。您可以通过许多其他方式做到这一点。

diff --old-line-format '%L' --new-line-format '' --unchanged-line-format ''  File-out File-Reference

Will produce an output of only showing the lines that can be found only in File-out, but it won't provide line numbers. If you really need that in your output:

    diff --old-line-format '%L' --new-line-format '' --unchanged-line-format ''  <(nl File-out) <(nl File-Reference)

should work.

Update: answering the comment below:

diff --old-line-format '%L' \
     --new-line-format '' \
     --unchanged-line-format '' \
     <(nl File-out) <(nl File-ref) | \
awk '{print $1 "p"}' > BUGLINEPRINTER.sed && \
sed -n -f BUGLINEPRINTER.sed File-In > File-In-bugs

Will do what you want. You can do it many other ways OTOH.
