带有简单 FC 命令的批处理文件永远运行

Question

为什么我的简单批处理文件运行总是一遍又一遍地打印出 .bat 文件中的行

我的fc.bat文件内容

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

我的桌面目录/

fc.bat
file1.txt
file2.txt!

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

输出是

...
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"
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"

看起来您的批处理文件处于无限循环中，一遍又一遍地调用自身。

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

即调用fc.bat，即运行调用相同的命令。默认情况下，批处理文件打印出它们运行的代码行，这就是您看到该输出的原因。
