batch file multiple actions under a if condition

问题

Is there a way to put multiple actions under a if condition? Like this:

if not exist MyFolderName (
ECHO create a folder
mkdir MyFolderName
)

回答1:

You can use & to join commands and execute them on the same line.

So your syntax should look like:

if not exist MyFolderName ECHO "Create a folder" & mkdir MyFolderName

UPDATE

Or you can use labels to jump to a section containing the commands you want to execute, for example:

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.

Yes, there is!

Check the link below, but remember: you must write the code exactly as the example is shown (all the spaces and parentheses).

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 else too.
