2. `git branch`

git branch - 查看本地分支
git branch -r - 查看远程分支
git branch -a - 查看本地仓库和远程分支 (a 是 all 的简写)

strong@foreverstrong:~/darknet_work$ cd dbscan_clustering_algorithm/
strong@foreverstrong:~/darknet_work/dbscan_clustering_algorithm$ git status
On branch master
Your branch is up-to-date with 'origin/master'.

3. `git branch dbscan_dev` - `git checkout dbscan_dev`

git branch dbscan_dev - 新建本地分支 dbscan_dev
git checkout dbscan_dev - 切换到本地分支 dbscan_dev

git checkout -b dev
一条命令等同于以下两条命令
git branch dev
git checkout dev

5.1 fatal: The current branch dbscan_dev has no upstream branch.

strong@foreverstrong:~/darknet_work/dbscan_clustering_algorithm$ git push
warning: push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:git config --global push.default matchingTo squelch this message and adopt the new behavior now, use:git config --global push.default simpleWhen push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)fatal: The current branch dbscan_dev has no upstream branch.
To push the current branch and set the remote as upstream, usegit push --set-upstream origin dbscan_devstrong@foreverstrong:~/darknet_work/dbscan_clustering_algorithm$
