批处理：当所述版本使用点和不同数量的数字时，通过 GEQ 比较版本号
Batch: Comparing version numbers via GEQ when said version uses dots and varying number of digits
我一直在使用以下 CMD 代码来检查 Edge 版本，但是从 99 到 100 的转变似乎对代码造成了影响。
FOR /F "Tokens=2*" %%G IN ('REG QUERY "HKLM\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{56EB18F8-B008-4CBD-B6D2-8C97FE7E9062}" /V "pv" ^| FINDSTR "REG_SZ"') DO (IF %%H GEQ 100.0.1185.29 (ECHO Microsoft Edge is version %%H and does not require an update. & GOTO SomethingElse) ELSE (ECHO Microsoft Edge is version %%H and requires an update. & GOTO MSEdgeInstall))
现在认为，例如99.9.1150.30高于100.0.1185.29。现在，如果我要删除这些点，它会意识到 999115030 实际上小于 1000118529。有一些关于点和额外数字的存在导致 cmd 中的计算失败。
有什么聪明的方法可以解决这个问题，还是我必须在从现在开始进行比较之前从注册表查询中删除这些点？
取决于你想要version-matching走多远。
如果只想匹配主版本，那么
FOR /F "Tokens=3*delims=. " %%H IN ('REG QUERY "HKLM\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{56EB18F8-B008-4CBD-B6D2-8C97FE7E9062}" /V "pv" ^| FINDSTR "REG_SZ"') DO (IF %%H GEQ 100 (ECHO Microsoft Edge is version %%H.%%I and does not require an update. & GOTO SomethingElse) ELSE (ECHO Microsoft Edge is version %%H.%%I and requires an update. & GOTO MSEdgeInstall))
不然就更复杂了。您的代码将检测到的版本与所需版本匹配为 string，因为这两个字符串不是纯数字的。即使删除点，您也需要单独比较每个组件，因为版本 100.1 会小于 99.10 (1001 < 9910).
请注意，我已将元变量从 %%G 更改为 %%H
我建议
FOR /F "Tokens=3" %%H IN ('REG QUERY "HKLM\SOFTWARE\WOW6432Node\Microsoft\EdgeUpdate\Clients\{56EB18F8-B008-4CBD-B6D2-8C97FE7E9062}" /V "pv" ^| FINDSTR "REG_SZ"') DO (call :vercmp %%H 100.0.1185.29 & if defined vergt (ECHO Microsoft Edge is version %%H and does not require an update. & GOTO SomethingElse) ELSE (ECHO Microsoft Edge is version %%H and requires an update. & GOTO MSEdgeInstall))

@ECHO OFF

虽然 Magoo 的代码在某处对我来说出错了，或者我不够聪明，无法理解它，但它确实给了我一个很好的建议，让我可以单独比较每个数字，所以感谢你的 Magoo。我会投票给你，但我的排名显然太低了。
