如何在批处理文件中的“If”中使用多个条件？(How can I use multiple conditions in “If” in batch file?)

如何在批处理文件中的“If”中使用多个条件？(How can I use multiple conditions in “If” in batch file?)

我可以在批处理文件中使用“或”/“和”来指定多个条件吗？

如果不是那么复杂，我至少可以使用如下的东西：

if value1 < value < value2

基本上我的目的是检查当前系统时间是否落在某个时间间隔（准确地说是2.05 AM和7.55 AM），如果是，则执行某些命令。

Can I specify multiple conditions with "or"/"and" in batch file if block?

If not that complex, can I at least use something like:

if value1 < value < value2

Basically my purpose is to check whether current system time falls in a certain interval(2.05 AM and 7.55 AM to be precise) and if it does, to execute certain commands.

添加到dbenham的答案，您可以使用if和goto语句的组合模拟两个逻辑运算符（AND，OR）。

测试条件1和codition2 ：

if <condition1> if <condition2> goto ResultTrue :ResultFalse REM do something for a false result goto Done :ResultTrue REM do something for a true result :Done

要测试condition1或codition2 ：

if <condition1> goto ResultTrue if <condition2> goto ResultTrue :ResultFalse REM do something for a false result goto Done :ResultTrue REM do something for a true result :Done

标签当然是任意的，只要它们是唯一的，你可以选择它们的名字。

Adding to dbenham's answer, you can emulate both logical operators (AND, OR) using a combination of if and goto statements.

To test condition1 AND codition2:

if <condition1> if <condition2> goto ResultTrue :ResultFalse REM do something for a false result goto Done :ResultTrue REM do something for a true result :Done

To test condition1 OR codition2:

if <condition1> goto ResultTrue if <condition2> goto ResultTrue :ResultFalse REM do something for a false result goto Done :ResultTrue REM do something for a true result :Done

The labels are of course arbitrary, and you can choose their names as long as they are unique.
