batch file multiple actions under a if condition
提问by 5YrsLaterDBA
Is there a way to put multiple actions under a if condition? Like this:
有没有办法在 if 条件下放置多个动作？像这样：
if not exist MyFolderName (
ECHO create a folder
mkdir MyFolderName
)

You can use &to join commands and execute them on the same line.
您可以使用&来连接命令并在同一行上执行它们。
So your syntax should look like:
所以你的语法应该是这样的：
if not exist MyFolderName ECHO "Create a folder" & mkdir MyFolderName
UPDATE
更新
Or you can use labels to jump to a section containing the commands you want to execute, for example:
或者您可以使用标签跳转到包含您要执行的命令的部分，例如：
if not exist MyFolderName GOTO DOFILESTUFF
:AFTER
...
EXIT
:DOFILESTUFF
ECHO "Create a folder"
mkdir MyFolderName
GOTO AFTER

'&' operator works perfectly as mjgpy3 explained. Also, We can add more then 2 statement using &. I have checked with 3 ststement and it works.
'&' 运算符与 mjgpy3 解释的一样完美。此外，我们可以使用 & 添加多于 2 个语句。我已经检查了 3 ststement 并且它有效。

Yes, there is!
就在这里！
Check the link below, but remember: you must write the code exactly as the example is shown (all the spaces and parentheses).
检查下面的链接，但请记住：您必须完全按照示例所示编写代码（所有空格和括号）。
Can I have an IF block in DOS batch file?
You can nest other if statements inside if statements, as long as you follow the example. And it works without elsetoo.
只要遵循示例，您就可以在 if 语句中嵌套其他 if 语句。它也可以工作else。
