What is the difference between "git branch" and "git checkout -b"?
提问by Adrien Joly
I used git checkout -bto create a new branch. I think that git branchdoes the same thing.
How do these two commands differ, if they differ at all?
我曾经git checkout -b创建一个新分支。我认为这git branch也是同样的事情。如果这两个命令完全不同，它们有何不同？
回答by Fatih Acet
git checkout -b BRANCH_NAMEcreates a new branch and checks out the new branch while git branch BRANCH_NAMEcreates a new branch but leaves you on the same branch.
git checkout -b BRANCH_NAME创建一个新分支并签出新分支，同时git branch BRANCH_NAME创建一个新分支但将您留在同一个分支上。
In other words git checkout -b BRANCH_NAMEdoes the following for you.
换句话说git checkout -b BRANCH_NAME，为您执行以下操作。
git branch BRANCH_NAME # create a new branch
git checkout BRANCH_NAME # then switch to the new branch
回答by manojlds
git branchcreates the branch but you remain in the current branch that you have checked out.
git branch创建分支，但您仍保留在已签出的当前分支中。
git checkout -bcreates a branch and checks it out.
git checkout -b创建一个分支并检查它。
It could be considered a short form of:
它可以被认为是以下的一种简短形式：
git branch name
git checkout name

git branch:Shows all your branchesgit branch newbranch:Creates a new branchgit checkout -b newbranch:Creates a new branch and switches to that branch immediately. This is the same asgit branch newbranchfollowed bygit checkout newbranch.
git branch:显示你所有的分支git branch newbranch:创建一个新分支git checkout -b newbranch：创建一个新分支并立即切换到该分支。这与git branch newbranch后面的 相同git checkout newbranch。

Full syntax:
完整语法：
git checkout -b [NEW_BRANCH] [FROM_BRANCH]
The [FROM_BRANCH] is optional. If there's no FROM_BRANCH, git will use the current branch.
[FROM_BRANCH] 是可选的。如果没有 FROM_BRANCH，git 将使用当前分支。

There is also another flag to mention, which is relative to these..
还有一个flag要提，就是相对于这些..
git checkout -B BRANCH_NAME
This is a very useful command that i've been using recently. This command checks out the branch you specify, and resetsthe branch based on the source branch.
这是我最近一直在使用的一个非常有用的命令。此命令检出您指定的分支，并根据源分支重置分支。
回答by Pshemy108
There are forms of both commands that are similar (looking at git-scm docs Version 2.11.1):
这两个命令的形式相似（查看 git-scm 文档版本 2.11.1）：
git branch <branchname> <start-point>
and
和
git checkout -b <new_branch> <start_point>
The latterexecuting the branch command first and then adding the checkout. In that form explicitly references to git-branch's doc:
在后者的第一执行分支命令，然后加入结帐。以这种形式明确引用 git-branch 的文档：
Specifying -b causes a new branch to be created as if git-branch[2] were called and then checked out
指定 -b 会导致创建一个新分支，就像调用了 git-branch[2] 然后检出一样

Essentially :
本质上 ：
A-git branch lets you create a branch plain and simple.
A-git branch 可以让你创建一个简单明了的分支。
B -git checkout -b allows you to create a branch and switch to it at the same time.
B -git checkout -b 允许您创建一个分支并同时切换到它。
When will you use which ? 1- git branch when you want to create a branch but stay on the current branch. 2- git checkout -b when you want to create and switch. If you look at it is intuitive to create a branch and switch to it. So the choice is yours :)
你什么时候用哪个？1- git branch 当你想创建一个分支但留在当前分支上时。2- git checkout -b 当你想创建和切换时。如果你看一下，创建一个分支并切换到它是很直观的。所以选择是你的:)
