比较两个文件所需的批处理文件

Question

这是我在Windows批处理文件中的要求，我尝试了以下操作

Example:
f1.txt
sam
varun
ramesh
babu

f2.txt
babu
sam

我需要的输出

varun
ramesh

该程序

@echo on
SETLOCAL EnableDelayedExpansion
for /F "tokens=* delims=." %%a in (f1.txt) do (
    call :myInnerLoop "%%a"
)

echo out of inner loop
)
goto :eof


:myInnerLoop
for /F "tokens=* delims=." %%b in (f2.txt) do (
    if "%~1"=="%%b" (
    echo inside inner loop
        goto :next
    ) else ( 
        echo %%a >> "E:\test\diff.txt"
    )
:next
goto :eof

但它不能正常工作对我有帮助。

即使我尝试了diff实用程序，也从http://gnuwin32.sourceforge.net/packages/diffutils.htm没有帮助。

Answer 1

您的代码几乎是正确的，但是您有一些（）错误。 试试这个：

@echo off
del d:\test\windows\comp\diff.txt
SETLOCAL EnableDelayedExpansion
for /F "tokens=* delims=." %%a in (f1.txt) do (
    echo %%a
    call :myInnerLoop "%%a"
)

echo out of inner loop
goto :eof

:myInnerLoop
for /F "tokens=* delims=." %%b in (f2.txt) do (
    echo "x: " %~1
    echo "y: " %%b
    if "%~1"=="%%b" (
        echo next
        goto :next
    )
)
echo "Log " %~1
echo %~1 >> "d:\test\windows\comp\diff.txt"

:next
goto :eof

您在寻找comp命令吗？

Compares the contents of two files or sets of files.

COMP [data1] [data2] [/D] [/A] [/L] [/N=number] [/C] [/OFF[LINE]]

  data1      Specifies location and name(s) of first file(s) to compare.
  data2      Specifies location and name(s) of second files to compare.
  /D         Displays differences in decimal format.
  /A         Displays differences in ASCII characters.
  /L         Displays line numbers for differences.
  /N=number  Compares only the first specified number of lines in each file.
  /C         Disregards case of ASCII letters when comparing files.
  /OFF[LINE] Do not skip files with offline attribute set.

To compare sets of files, use wildcards in data1 and data2 parameters.
