Batch file 批处理文件命令-Findstr、拆分和文件名变量

我是批处理命令的新手，一直在尝试将手动操作自动化。我有一个每天下载的日志文件，然后我使用Findstr（输出到另一个文件）搜索其中的某些项目，然后将找到的内容拆分为较小的文件

我在生成文件名和文件名变量以及在代码中使用这些变量时遇到了麻烦。拆分器代码是给我的，所以我只是想把Findstr合并到其中。有什么建议或者我做错了什么

例如：

它将通过

10-06-16_file.log

查找活动ID为

1234

的任何行，并将它们输出到

fnd_10-06-16_file.log

如果

fnd_10-06-16_file.log

文件大小大于177000kb，则将该文件拆分为名为

2SplitFile1_Pepsi.log

，

2SplitFile2_Pepsi.log

，

2SplitFile3_Pepsi.log

的较小文件

首先，将%%a in（%fnd\u impressionfile%）的

设置fnd\u impressionfile\u sz=%%~zfnd\u impressionfile

更改为

，设置fnd\u impressionfile\u sz=%%~za

然后，再次检查maxbytesize。您的描述是kb，但批处理意味着字节。fnd_impressionfile_sz包含字节值

我看到的另一件事是，如果fnd_impressionfile_sz>maxbytesize，则在

中使用重定向操作符>。您应该将其更改为
GTR
或
GEQ
。请参阅
