# Git - git merge 分支合併

## git merge 分支名
* **git merge 分支名** 用來合併分支
目前我們有 **feature1** 與主幹 **master** 兩個分支

若我們想要將 **feature1** 合併到 **master** 裡，我們需要先移動到 **master** 分支

    design1@DESKTOP-2SJKDSH MINGW64 ~/Desktop/Gene/project (feature1)
    $ git checkout master
    Switched to branch 'master'
    M       index.html

    design1@DESKTOP-2SJKDSH MINGW64 ~/Desktop/Gene/project (master)
    $ git branch 
      feature1
    * master

接著使用 **git merge feature1** 指令，將 **feature1** 合併到 **master**
(預設會使用 Fast-forward 方式合併)

    design1@DESKTOP-2SJKDSH MINGW64 ~/Desktop/Gene/project (master)
    $ git merge feature1
    Updating 68e8338..56575de
    Fast-forward
     css/all.css | 0
     1 file changed, 0 insertions(+), 0 deletions(-)
     create mode 100644 css/all.css

使用 **git log** 查看，可以看到 **feature1** 已經成功合併到 **master** 了

    $ git log
