unix-diff命令以单行/每行格式输出 [英] unix - diff command to output in single-line-per-difference format

问题描述

我的cygwin中diff的版本有许多高级选项，使我可以每行打印出一个差异。

The version of diff in my cygwin has a number of advanced options which allow me to print out one difference per line.

给出两个文件one.txt和两个.txt。

Given two files one.txt and two.txt.

one.txt：

one
two
three
four
five
six

two.txt

one
two2
three
four
five5
six

然后在cygwin中使用以下选项/参数运行diff：

And running diff in cygwin with the following options/parameters:

diff -y --suppress-common-lines one.txt two.txt

给出以下输出：

two   |two2
five  |five5

这是我追求的格式类型，每行打印一个差异。
在我的dev solaris框上，不支持 -y选项，因此我的输出看起来像这样：

This is the type of format I'm after whereby one difference is printed out per line. On my dev solaris box, the "-y" option is not supported, so I'm stuck with an output which looks like this:

2c2
< two
---
> two2
5c5
< five
---
> five5

有人知道我可以在此solaris盒上每行输出一个差异的方法吗？ ？也许使用sed / awk一个内衬来按摩来自这个更原始的diff输出的输出？ （请注意，我无法在此solaris盒子上安装最新的diff版本。）。

Does anyone know of a way I can get an output of one difference per line on this solaris box? Maybe using a sed/awk one liner to massage the output from this more primitive diff output? (Please note, I am not able to install a more up-to-date diff version on this solaris box).

谢谢！

推荐答案

使用GNU差异。

http://www.gnu.org/software/diffutils/

您可以构建和安装它进入您的本地目录，不是吗？如果您有主目录，编译器和make，则可以构建自己的GNU差异。

You can build and install it into your local directory, no? If you have a home directory and a compiler and a make, you can build your own GNU diff.

我没有Solaris，但我无法想象会比这更多：

I don't have Solaris, but I can't imagine it would be much more than this:

./configure --prefix=/home/bob
make
make install

不需要root特权。
