What does the
-p flag do in
-p flag will create nested directories, but only if they don't exist already.
For example, suppose you have a directory
/foo that you have write permissions for.
mkdir -p /foo/bar/baz # creates bar and baz within bar under existing /foo
It is also an idempotent operation, because if you run the same command over again, you will not get an error, but nothing will be created.
-p flag allows a parent folder to be created along with the nested folder.
it would return the following error :
mkdir: cannot create directory ‘directory/nested_directory’: No such file or directory
But if you use
-p such as:
mkdir -p directory/nested_directory
It will create both directory and it's nested nested_directory folders successfully.
