从for循环

Question

我有各种文件的日期作为明智 cpms_2015_09_01.txt lms_2015_07_10.txt kmps_2015_10_07.txt lmps_2015_10_07.txt cpmgs_2015_10_07.txt 我想从“for循环中删除输出中删除特定文件“今天的日期名称的文件 我该如何做到这一点，我写了一个代码，我可以将所有文件的文件路径存储在XCOUNT_1 = D：\ check \ cpms_2015_09_01.txt等 中，但是今天不应该没有XCOUNT文件名像％_2015_10_07％ 我对下面指出的这段代码感到震惊 DO（如果不是“％year％％day％ ％月％的.txt “==”！FTRIM %% J 1”

我的代码是下面

SETLOCAL ENABLEDELAYEDEXPANSION SETLOCAL SET/A MAXJ = 1 SET/AJ = 1 回波％ DATE％

一套年=％日期：〜-4,4％

一套年=％年：=％

集月=％日期：7,2〜％ 集月=％月：=％

集天=％日期：〜4.2％ 集天=％天：=％

FOR/F “有usebackq令牌= *” %%我（DIR /S /B D:\check\*.txt）DO（IF NOT “％，比去年％％一天％％，当月％.TXT” == “！FTRIM %% J 1”（

SET XCOUNT_!J!=%%~i 
SET FNAME_!J!=%%~ni 
SET MAXJ=!J! 
SET /A J+=1 
SET FTRIM_!nxi!=%%~nxi:~-10,10% 

PAUSE ） ）

Answer 1

冷杉最重要的是，除非您告诉批处理一个命令停止并且下一个命令开始，否则不能将所有代码放在同一行上。其次，您拥有的代码只能在命令提示符下使用，而不能在批处理文件中使用，因为在批处理文件中使用for循环变量时需要两个%。第三，set /a仅用于数学;存储字符串值时使用常规set命令。

最后（也是最重要的），您需要延迟扩展来正确迭代您的for循环内的计数器变量。

此批处理脚本应该工作：

@echo off 
setlocal enabledelayedexpansion 

set J=1 
for /R "D:\TEST" %%I in (*.txt) do (
    set XCOUNT_!J!=%%I 
    set /a J+=1 
) 

如果要排除从输出特定的文件，在if声明包裹set代码。

@echo off 
setlocal enabledelayedexpansion 

set J=1 
for /R "D:\TEST" %%I in (*.txt) do (
    if not "%%~nxI"=="test.txt" (
     set XCOUNT_!J!=%%I 
     set /a J+=1 
    ) 
) 

Answer 2

C:\Users\pwatson\bin>type atest.bat 
@ECHO OFF 
SETLOCAL ENABLEDELAYEDEXPANSION 
SET /A J=1 
SET /A MAXJ=0 
FOR /F "usebackq tokens=*" %%i IN (`DIR /S /B C:\Python27-32\*.exe`) DO (
    SET XCOUNT_!J!=%%~i 
    SET MAXJ=!J! 
    SET /A J+=1 
) 
SET XCOUNT 

这将产生：

C:\Users\pwatson\bin>call atest.bat 
XCOUNT_1=C:\Python27-32\python.exe 
XCOUNT_10=C:\Python27-32\Lib\site-packages\pip\_vendor\distlib\t64.exe 
XCOUNT_11=C:\Python27-32\Lib\site-packages\pip\_vendor\distlib\w32.exe 
XCOUNT_12=C:\Python27-32\Lib\site-packages\pip\_vendor\distlib\w64.exe 
XCOUNT_13=C:\Python27-32\Lib\site-packages\setuptools\cli-32.exe 
XCOUNT_14=C:\Python27-32\Lib\site-packages\setuptools\cli-64.exe

XCOUNT_21=C:\Python27-32\Scripts\easy_install-2.7.exe 
XCOUNT_22=C:\Python27-32\Scripts\easy_install.exe 
XCOUNT_23=C:\Python27-32\Scripts\pip.exe 
XCOUNT_24=C:\Python27-32\Scripts\pip2.7.exe 
XCOUNT_25=C:\Python27-32\Scripts\pip2.exe 
XCOUNT_3=C:\Python27-32\w9xpopen.exe 
XCOUNT_4=C:\Python27-32\Lib\distutils\command\wininst-6.0.exe 
XCOUNT_5=C:\Python27-32\Lib\distutils\command\wininst-7.1.exe 
XCOUNT_6=C:\Python27-32\Lib\distutils\command\wininst-8.0.exe 
XCOUNT_7=C:\Python27-32\Lib\distutils\command\wininst-9.0-amd64.exe

获取这些回母体环境是另一个问题。我希望dbenham可能会作出回应。
