I need a binary comparison tool for Win/Linux
提问by Dan
First of all, I don't need a textual comparison so Beyond Compare doesn't do what I need.
首先，我不需要文本比较，所以 Beyond Compare 不会做我需要的。
I'm looking for a util that can report on the differences between two files, at the byte level. Bare minimum is the need to see the percentage change in the file, or a report on affected bytes/sectors.
我正在寻找一个可以在字节级别报告两个文件之间差异的实用程序。最低限度是需要查看文件中的百分比变化，或有关受影响字节/扇区的报告。
Is there anything available to save me the trouble of doing this myself?
有什么可以避免我自己做这件事的麻烦吗？

I guess it depends on what exactly is contained in the file, but here's a quick one:
我想这取决于文件中包含的内容，但这里有一个快速的：
hexdump file1 > file1.tmp
hexdump file2 > file2.tmp
diff file1.tmp file2.tmp
Since 16 bytes are typically reported on each line, this won't technically give you a count of the bytes changed, but will give you a rough idea where in the file changes have occurred.
由于每行通常报告 16 个字节，因此从技术上讲，这不会为您提供更改的字节数，但可以让您大致了解文件中发生更改的位置。

UltraCompareis the best for binary comparison. It has a smart comparator that is really useful.
UltraCompare是二进制比较的最佳选择。它有一个非常有用的智能比较器。

ECMerge recently introduced a binary differ, it can compare files of several giga bytes (the limit is somewhere above the terabyte). it works on linux, windows, mac os x and solaris. it gives you byte by byte or block per block statistics.
ECMerge 最近推出了一个二进制差异，它可以比较几个千兆字节的文件（限制在tera字节以上）。它适用于 linux、windows、mac os x 和 solaris。它为您提供逐字节或每块数据块的统计信息。
You can parameter synchronization window (if desired) and minimal match.
您可以参数同步窗口（如果需要）和最小匹配。

There's Araxis Mergeavailable for windows. Here's a pagethat describes their binary comparison feature.
有适用于 Windows的Araxis Merge。这是一个页面，描述了他们的二进制比较功能。
