我需要比較兩個文本文件並希望將結果存儲在新文件中

Question

我需要比較兩個文本文件並希望將結果存儲在新文件中。這段代碼沒有幫助。

findstr /vixg:oldstatus.txt newstatus.txt > diff.txt 

它只是給newstatus.txt的輸出。它沒有顯示出差異。

Answer 1

也許這?:

@echo off 
for /f %%a in (oldstatus.txt) do (
findstr /i /v /c:"%%a" newstatus.txt >>diff.txt 
) 
pause 

的幫助與findstr命令：http://ss64.com/nt/findstr.htm
還看到：http://ss64.com/nt/fc.htm
和：http://ss64.com/nt/comp.htm

Answer 2

可以使用fc命令顯示兩個文件之間的差異。 /c選項會執行不區分大小寫的比較，如findstr的/i選項。

fc oldstatus.txt newstatus.txt >diff.txt 

從fc /?輸出：

Compares two files or sets of files and displays the differences between them 


FC [/A] [/C] [/L] [/LBn] [/N] [/OFF[LINE]] [/T] [/U] [/W] [/nnnn] 
    [drive1:][path1]filename1 [drive2:][path2]filename2 
FC /B [drive1:][path1]filename1 [drive2:][path2]filename2 

/A   Displays only first and last lines for each set of differences. 
/B   Performs a binary comparison. 
/C   Disregards the case of letters. 
/L   Compares files as ASCII text. 
/LBn  Sets the maximum consecutive mismatches to the specified 
      number of lines. 
/N   Displays the line numbers on an ASCII comparison. 
/OFF[LINE] Do not skip files with offline attribute set. 
/T   Does not expand tabs to spaces. 
/U   Compare files as UNICODE text files. 
/W   Compresses white space (tabs and spaces) for comparison. 
/nnnn  Specifies the number of consecutive lines that must match 
      after a mismatch. 
[drive1:][path1]filename1 
      Specifies the first file or set of files to compare. 
[drive2:][path2]filename2 
      Specifies the second file or set of files to compare.
