批处理-搜索变量是否包含空格 [英] Batch - Search if a variable contains spaces

问题描述

我有一个变量，需要检查它是否包含空格，如果存在则退出. 我有以下代码:

I have a variable that I need to check if it contains spaces, and exit if it does. I have this code:

if not [%VAR%]==[%VAR: =%] exit 1

..但不适用于空格.我可以将其用于其他字符.例如，查找"/"可以使用相同的代码:

.. but it does not work for spaces. I can use it for other characters though. For example looking for "/" works with same code:

if not [%VAR%]==[%VAR:/=%] exit 1

有办法吗?

谢谢

推荐答案

此操作应根据您的需要:双引号始终是空格和其他一些字符的解决方案.

This should do as you need: double quotes are always the solution for spaces, and also with some other characters.

if not "%VAR%"=="%VAR: =%" exit 1
