curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

### And that's all !
# I saw many fighting with finding first commit SHA or similar fancy thing.
# Here we just rely on the GH API, asking commits at 1 per page and parsing the last page number in the header of the reply (whose body only holds the last commit !)
# So this is robust and bandwidth efficient. :)

# If one want the commit count of a specific SHA, just use :
curl -I -k "https://api.github.com/repos/:owner/:repo/commits?per_page=1&sha=:sha" | sed -n '/^[Ll]ink:/ s/.*"next".*page=\([0-9]*\).*"last".*/\1/p'

Надо добавить удаленную ветку, чтобы она синхронизировалась через pull/push.
Сначала надо создать удаленную ветку:
git push origin origin:refs/heads/new_branch_name

Стянуть ее
git pull origin

Посмотреть появилась ли в списке удаленных веток:
git branch -r
