试图计算文件中的行数

Question

我需要计算文件（%LOGDIR%%NORMALMEMORY%）中的行数。

for / f循环对行进行计数，但是我不知道为什么它没有正确存储在%MAPCOUNT%变量中。

日志文件提供了此信息：

set /a MAPCOUNT=3

Commande ECHO activ�e.

Used map count is

Number of available maps is

Map state changed to NORMAL

---

FOR /f %%a in (%LOGDIR%%MAPMEMORY%) do (
    if "%%a" == "NORMAL" (
        echo MAP state is NORMAL
        for /f %%b in ('find /v /c "" ^< %LOGDIR%%NORMALMEMORY%') do set /a MAPCOUNT=%%b
        echo %MAPCOUNT%
        echo Used map count is %MAPCOUNT%

        echo Number of available maps is %DIRCOUNT%



        echo Map state changed to PENURIE
        echo PENURIE > %LOGDIR%%MAPMEMORY%
    )

我希望将行数存储在％MAPCOUNT％变量中。
