批處理文件運行永遠

Question

爲什麼我的簡單的批處理文件運行在永遠打印出只有線的.BAT文件內超過

我fc.bat文件內容

FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt" 

我的臺式機DIR/

fc.bat 
file1.txt 
file2.txt! 

Here is a image of my cmd prompt after double clicking fc.bat

輸出是

C:\Users\a\Desktop>FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt" 
C:\Users\a\Desktop>FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt"

C:\Users\a\Desktop>FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt" 
C:\Users\a\Desktop>FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt"

C:\Users\a\Desktop>FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt" 
C:\Users\a\Desktop>FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt"

它看起來像你的批處理文件是一個無限循環，一遍又一遍的調用自身。

FC "%USERPROFILE%\Desktop\file1.txt" "%USERPROFILE%\Desktop\file2.txt" 

這就是調用運行相同命令的fc.bat。默認情況下，批處理文件會打印出他們運行的代碼行，這就是您看到該輸出的原因。
