DOS脚本按内容删除相同的文件
我有一个目录,其中包含需要处理的数千个文本文件。其中一些文件是相同的,而其他文件是相同的,只是时间戳有几秒/毫秒的变化。我需要某种方法来自动删除相同的文件并只保留一个副本。
我在想这样的事情:
while there are files in the directory still
{
get file // e.g., file0001
while (file == file + 1) // e.g., file0001 == file0002 using 'fc' command
{
delete file + 1
}
move file to another directory
}
在 Microsoft Windows Server 2003 的 DOS 中,这样的事情可能吗?
I have a directory with several thousand text files that I need to process. Some of these files are identical while others are identical except the timestamp varies by a few seconds / milliseconds. I need some way to automate the deletion of identical files and only keep one copy.
I'm thinking of something like:
while there are files in the directory still
{
get file // e.g., file0001
while (file == file + 1) // e.g., file0001 == file0002 using 'fc' command
{
delete file + 1
}
move file to another directory
}
Is something like this even possible in Microsoft Windows Server 2003's DOS?

当然是。批量化一切皆有可能。 :D
这个批处理实际上并没有删除文件。它只是呼应了比较的结果。如果发现两个文件相同,则可以删除其中一个文件。
将代码另存为
CleanDuplicates.bat
并使用CleanDuplicates {Folder}
启动程序按原样提供,没有任何保证!我不想让你敲我的门,因为你的整个服务器都搞砸了。 ;-)
该代码实际上递归地调用自身。这也许可以用不同的方式来完成,但是嘿,它有效。它还会在新的 cmd 中重新启动,因为这使得清理变得更容易。我在 Windows Vista Business 中测试了该脚本,但它也应该可以在 Server 2003 上运行。嘿,它甚至还有帮助功能。 ;-)
它包含两个循环,每个循环返回每个文件,因此当您实现实际删除时,它可能会报告某些文件不存在,因为它们在较早的迭代中被删除。
Of course it is. Everything is possible in batch. :D
This batch doesn't actually delete files. It just echos the result of the comparison. You can delete either one of the files if you find two that are the same.
Save the code as
CleanDuplicates.bat
and start the program withCleanDuplicates {Folder}
Provided AS IS, without any guarantees! I don't want you knocking on my door because your entire server is messed up. ;-)
The code actually calls itself recursively. This could maybe be done in a different way but hey, it works. It also starts itself again in a new cmd, because that makes cleaning up easier. I tested the script in Windows Vista Business, but it should work on Server 2003 as well. Hey, it even has a help function. ;-)
It contains two loops that each return every file, so when you implement the actual deleting, it may report that some files don't exist, because they are deleted in an earlier iteration.
