If I try to run mkdir build to create a build directory, if the directory already exists, this error is thrown: A subdirectory or file build already exists.. I need to delete and overwrite this directory. What is the command for that?

You can delete the build directory with
rd /s /q build
or
if exist build rd /s /q build

For best results, run this command twice. It will sometimes fail if, e.g., Windows Search happens to be indexing that directory at just the wrong time. – Harry Johnston May 14 '19 at 05:28

I wanted to create directory only if it does not exist
If it exists, nothing to do
Below worked great in the bat file:
if not exist someDir1 mkdir someDir1

I don't think it is possible to use the mkdir command to do that natively (though if you were will to do a bit more scripting, it would be possible).
A simple alternative is the following command in powershell:
New-Item path -type directory -force
Where path is something like C:\users\name\build
For more on New-Item see: http://technet.microsoft.com/en-us/library/ee176914.aspx

I can't execute powershell as I'm calling this from a rake script. – Shawn Mclean Aug 19 '12 at 21:29

You can try the rd command to remove the directory. You have to ensure the directory is empty first though.

1Please read the question again carefully. Your answer does **not** answer the original question. OP is using Windows **not** Unix. – DavidPostill Aug 27 '16 at 07:16
