Create Github repository from API

The following works:

curl -H "Authorization: token abcdefghijklmnopqrstuvwxyz1234567890abcd" 
  --data '{"name":"name-foo"}' https://api.github.com/user/repos

NAME='name-foo'
TOK='abcdefghijklmnopqrstuvwxyz1234567890abcd'
BASE='https://api.github.com/'
EXT='user/repos'
URL=$BASE$EXT
curl -H "Authorization: token $TOK" --data "{\"name\":\"$NAME\"}" $URL

One can use personal access tokens instead of OAuth.

The YOUR_TOKEN value in the "Authorization: token YOUR_TOKEN" section of the curl command can be obtained as follows.

1. Upper right corner, click User
2. Settings
3. Personal Access Tokens
4. For scopes, select Repos.
5. Create New Token.
