我有这个脚本：
for /f "delims=" %%a in (data_A.txt) DO (
set "flag="
for /f "delims=" %%b in (data_B.txt) do (
if "%%a"=="%%b" CALL :flagit
)
if not defined flag >>notmatch.txt echo %%a
)
:flagit
set flag=1
goto :eof
我正在比较两个文本文件之间的每一行，以确定不匹配的条目。这些文件包含校验和哈希值和相对路径信息。
它可以工作，但是速度很慢。一个具有100,000个条目的文件要花费两个半小时，而且我必须做两次，因为我必须比较两种方式来捕获A上可能不在B上但可能不在A上的任何条目。数据也不一定按任何特定的排序顺序。
我正在寻找：
我很习惯处理前两个文件（文件不在A / B上），因为一旦获得“不匹配”的条目，它们应该很少，并且比较两者上是否存在相对路径（我希望）。但是最后一个是实时的。
数据示例：

for循环的工作方式是扫描另一个文件，直到找到不匹配的文件，然后将其输出到日志文件，然后转到下一个文件。似乎应该有一种方法，一旦文件已匹配或不匹配，便从搜索中将其删除。
编辑-好的，我有点弄错了PowerShell。比较对象工作良好，但只需要弄清楚如何仅显示A和B上都存在的不同文件，并记录以将仅在A上和仅在B上的文件分开即可...
要在PowerShell中执行相同的操作，可以使用此答案中提到的@JoseZ方法，并且只需进行最少的编辑，即可获得保存在NoMatch.txt文件中的每个文件中不同的字符串：
Set-Location -Path "D:\Your\Folder"; Clear-Content -path ".\NoMatch.txt"; $filebefore=".\data_A.txt"; $file_after=".\data_B.txt"
### Compare-Object way
$array = Compare-Object $(Get-Content $filebefore) $(Get-Content $file_after)
$array | where {$_.SideIndicator -eq "<="} | Format-Table -Property InputObject -AutoSize -HideTableHeaders
### -NotIn operator way
$(Get-Content $filebefore) | Where-Object {$_ -notIn $(Get-Content $file_after)} | Out-File ".\NoMatch.txt" -Append
$(Get-Content $file_after) | Where-Object {$_ -notIn $(Get-Content $filebefore)} | Out-File ".\NoMatch.txt" -Append
>Get-Content ".\NoMatch.txt"

对于较短的字符串，您可以尝试使用 Findstr /vixg:data_A.txt data_B.txt
/I Specifies that the search is not to be case-sensitive.
/X Prints lines that match exactly.
/V Prints only lines that do not contain a match.
/G:file Gets search strings from the specified file(/ stands for console).观察：为了Findstr使此比较/查找相同/不同的字符串，总长度限制为最大250个字符：
(String_A).Length + (String_B).Length <= 250 characters
-这就是为什么我在以下示例中将您的字符串减少到最多125个字符的原因：
仅在文件data_A.txt中的最后一行和第一个字符上与文件data_B.txt不匹配，并且将保存在文件NoMatch.txt中
@echo off
