我有一份载有这一格式的文件:

<somecharacters> 1 <somecharacters>
<somecharacters> 2 <somecharacters>
<somecharacters> 4 <somecharacters>
<somecharacters> 9 <somecharacters>

我需要删除最大的数字。 我尝试使用<条码>FINDSTR和FIND,但仅仅没有Windows指挥线方面的足够经验......

最佳回答

如果你档案中的所有内容都真的一致地照样编排,那么这项工作就应当做到(我使用了属性而不是内文本)。

@echo off
setlocal enableDelayedExpansion
set maxPort=0
for /f "tokens=6 delims=<./ " %%N in (test.txt) do (
  if %%N gtr !maxPort! set maxPort=%%N
)
echo maxPort=%maxPort%

但是,如果你有另外一条线,看上去应当忽略的不同之处,那么你就希望利用联邦移民管制局来过滤你不想穿透的界线。 联邦移民局的指挥权将包含在IN()条款内。 移民归化局对经常表达的支持有限,这些表达可能满足你们的需要。
