线与批处理的比较

Question

我想将.txt的第一列与每行after.txt行的第一列进行比较(第一个，第二个，第二个，依此类推(。现在输出，我仅获得最后一个值E992A84B8C8A1FEF3B94242403D5D84B两次。我的问题是如何比较所有行并获取结果消息？

 FOR /F "tokens=1 delims= " %%G IN (before.txt) DO set variable1=%%G
    FOR /F "tokens=1 delims= " %%I IN (after.txt) DO set variable2=%%I 
    echo !variable1!
    echo !variable2!
 if /I !variable1!==!variable2! (
     echo !variable1! !variable2! md5sum check is ok
     )

aschipl的批次调整了您的要求：

:: Q:Test2018427SO_50067394.cmd
@echo off
setlocal EnableExtensions EnableDelayedExpansion
set "FILE1=after.txt"
set "FILE2=before.txt"
:: set "RET=Comparison.txt" & rem // (none to output to console)
if not defined RET set "RET=con"
for /F %%C in ('^< "%FILE1%" find /C /V ""') do set "NUM1=%%C"
4< "%FILE1%" 3< "%FILE2%" > "%RET%" (
     for /L %%I in (1,1,%NUM1%) do (
         set "LINE1="
         0<&4 set /P "LINE1="
         set "LINE2="
         0<&3 set /P "LINE2="
         if not ErrorLevel 1 If "!LINE1:~0,32!"=="!LINE2:~0,32!" echo(!LINE1:~0,32! !LINE2:~0,32! md5sum check is ok

Answer 2

在此答案中描述了并行读取几个文件的常用方法，包括通过 for /F命令读取第一个文件和通过重定向的set /P命令(s(读取第一个文件(s(。例如：

@echo off
setlocal EnableDelayedExpansion
rem First file is read with FOR /F command
rem Second file is read via redirected stdin
< after.txt (for /F %%G in (before.txt) do (
   rem Read next line from after.txt
   set /P "variable2="
   rem Compare first token of both files
   for /F %%I in ("!variable2!") do (
      if /I %%G==%%I (
         echo %%G %%I md5sum check is ok
      )
   )
))

请注意，默认的for /F行为是由Space划定的第一个令牌，因此"tokens=1 delims= "选项不是必需的...

但是，如果文件很小，则可以使用更简单的方法：

@echo off
for /F "tokens=1,2 delims=: " %%F in ('findstr /N "^" before.txt') do (
   for /F "tokens=1,2 delims=: " %%H in ('findstr /N "^" after.txt') do (
      if %%F equ %%H if /I %%G == %%I (
         echo %%G  %%I md5sum check is ok
      )
   )
)

在此方法中，findstr /N "^"命令用于枚举两个文件中的所有行，因此if %%F equ %%H命令都用于在两个文件中同步(选择相同(行。此方法不是有效的，因此如果文件不小，则需要更长的时间...

Answer 4

您可以set 2计数器。当计数器相等时，您可以测试2列。这样，您还会得到错误的行号！

@echo off
setlocal enabledelayedexpansion
set $counter1=1
for /f "delims= " %%a in (before.txt) do (
   set $counter2=1
   for /f "delims= " %%b in (after.txt) do (
        if !$counter1!==!$counter2! (
            if "%%a"=="%%b" (echo line !$counter1! cheksum OK
            ) else (echo line !$counter1! cheksum KO)
        )
        set /a $counter2+=1
   )
   set /a $counter1+=1
   )

输出：

line 1 cheksum OK
line 2 cheksum OK
line 3 cheksum OK
line 4 cheksum OK
line 5 cheksum OK
line 6 cheksum OK
line 7 cheksum OK
line 8 cheksum OK
line 9 cheksum KO
line 10 cheksum OK
line 11 cheksum OK
