The condition for bash is if there is a “name” folder on the Yandex disk, then do not create a dad. How?

Question

Yandex.Disk

I make a backup of sites through a bash script and through it I throw backups on a Yandex disk. But before that, I need to create a folder with a specific name on the Yandex disk (via the same bash script), and if such a folder already exists, then there is nothing not to create.
I implemented this with two lines:
The first line - creates a folder with the name that I specified
The second line - throws my backup into this folder

curl -X MKCOL --user login:password https://webdav.yandex.ru/backup_sites/name_folder/
curl --user login:password -T /home/2/d008/htdocs/backup/project https://webdav.yandex.ru/backup_sites/name_folder

The problem is this: if the folder already exists, I get an error - "mkdir: resource already exists"
How can I make the folder be created only if it does not exist (and so that this is not considered an error)?

Answer 1

Why make it so difficult.
Once with your hands, make folders, let the script fill in what you need.
