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. May 14, 2019 at 5:28
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

I can't execute powershell as I'm calling this from a rake script. Aug 19, 2012 at 21:29
You can try the rd
command to remove the directory. You have to ensure the directory is empty first though.
