Is it possible to create a new repository in Bitbucket by using command line Git? I have tried the following:
git clone --bare https://username@bitbucket.org
You can use the Bitbucket REST API and cURL. For example:
curl --user login:pass https://api.bitbucket.org/1.0/repositories/ \
--data name=REPO_NAME
to create new repository named REPO_NAME.
See Use the Bitbucket REST APIs for more information.
UPDATE
For Bitbucket V2 specifically, see POST a new repo
