如何清除从命令行通过"set/p var1 ="设置的变量 [英] how to clear a variable which is set from command line by "set /p var1="

问题描述

在Windows批处理文件中，我接受来自set /p var1=的用户输入的变量，使用var1后，我不知道如何重置/清除其值.

In Windows batch files, I accept variable from user input by set /p var1=, after var1 is used, I don't know how to reset/clear its value.

如果我不重置/清除其值，则当用户再次遇到set /p var1=时，用户将直接输入.先前的输入值仍将存在.我不想要它，如何将其重置为新用户输入?

If I don't reset/clear its value, when user meets set /p var1= again, and user enter directly. the previous input value will be still there. I don't want it, How to reset it for new user input?

推荐答案

清除变量，无论如何设置:

To clear a variable, regardless how it was set:

set "var1="
