Question

对我来说，每天搜索一次.csv文件夹中的所有C:\csvtest个文件的最佳方法是什么？

我只对标记名以.REG102结尾的行感兴趣，如果它是<=3000，如果是，则将其输出到同一位置的文本文件中。

e.g。 matchedfilename msg (IDG00105--IDG00105) 2017_10_30_13_30_33.csv 其中matchedfilename是找到成功条目的文件的名称。

.csv文件内容：

[Data]  
Tagname,TimeStamp,Value,DataQuality  
IDG00105--IDG00105.REG96,2017-10-30 13:30:33.000,6774,Good

Answer 1

最简单的方法是使用powershell：

powershell "import-csv data.csv| where {$_.Value -le 3000  -and $_.Value -gt 0}"

纯批次：

@echo off
setlocal enableDelayedExpansion
for /f "usebackq skip=1 tokens=1-4 delims=," %%a in ("data.csv") do (
    set /a value=%%c
    if !value! LEQ 3000 if !value! GTR 0 (
       (echo(%%a,%%b,%%c,%%d)
    )
)

Answer 2

如果我已正确理解您的任务，可能会使用以下内容：

@Echo Off
SetLocal EnableDelayedExpansion

Set "sD=C:\csvtest"
Set "fM=*.csv"
Set "sM=.REG102,"
Set "mV=3000"
Set "oF=output.txt"

If /I Not "%CD%"=="%sD%" CD/D "%sD%" 2>Nul||Exit/B
If Not Exist "%fM%" Exit/B
::If Exist "%oF%" Del "%oF%"

For /F "Tokens=1*Delims=:" %%A In ('FindStr/L "%sM%" "%fM%"'
) Do For /F "Tokens=1-3Delims=," %%C In ("%%~B"
) Do If "%%E" LEq "%mV%" (Set "nV=%%~nC"&Set "tV=%%~nD"
    Set "tV=!tV:-=_!"&Set "tV=!tV::=_!"
    >>"%oF%" Echo %%~nA msg (!nV:*:=!^) !tV: =_!%%~xA)

您可以根据需要更改第4-8行的源目录，文件掩码，搜索掩码，最大值和输出文件。如果您希望每次脚本运行时都将新鲜内容写入输出文件，请从行12中删除前两个字符。
