Git 操作小结

Git alias

修改~/.gitconfig

[color]
        ui = true
[core]
        editor = vim
        excludesfile = ~/.gitignore
        deltaBaseCacheLimit = 1G
[alias]
        co = checkout
        ci = commit
        ca = commit --amend
        st = status
        fr = !git fetch && git rebase
        sp = !git stash && git pull && git stash pop
        br = branch
        dc = diff --cached
        sst = status -s
        hist = log --pretty=format:\"%h %ad | %s%d [%an]\" --graph --date=short
        chist = log --oneline --graph --decorate --branches
        review = push origin HEAD:refs/for/master
[push]
        default = simple

新建分支

wip Work in Progress

1	git co -b wip-xxx-xx

切换分支

查看有哪些分支

git branch -a

* master
  remotes/origin/HEAD -> origin/master
  remotes/origin/master
  remotes/origin/nnvm
  remotes/origin/piiswrong-patch-1
  remotes/origin/v0.9rc1

git checkout -b 本地分支名 origin/远程分支名（推荐使用）：原因：可以直接跳转到分支

1
2
3

git checkout -b v0.9rc1 origin/v0.9rc1
Branch v0.9rc1 set up to track remote branch v0.9rc1 from origin.
Switched to a new branch 'v0.9rc1'

＃已经切换到v0.9rc1分支了

Push代码

1 2	git ci -m "some word" git push -u origin wip-xxx-xx

推送本地新分支

先确保当前已在local_branch分支，然后push

1
2
3

git checkout local_branch

git push origin local_branch:remote_branch

合并多个commits

设置起点

以master 为起点
当然 origin/master 也可以改为对应起点的commit hash值
1
git rebase -i origin/master
从HEAD版本开始往过去数3个版本

1	git rebase -i HEAD~3

指名要合并的版本之前的版本号
1
git rebase -i 3a4226b
3a4226b 不会参与合并

选择要合并的提交

执行rebase之后，会弹出一个窗口

1
2
3

pick 3ca6ec3   '注释**********'
pick 1b40566   '注释*********'
pick 53f244a   '注释**********'

一共有三种状态

pick
保留commit状态，不合并该次提交
s | squash

use commit, but meld into previous commit
使用此次Commit，但会被合并到前一个Commit
f | fixup

like “squash”, but discard this commit’s log message
跟squash一样，唯一的不同时丢弃掉Commit message。
就是 git commit -m "Commit message" ，里边说的话丢弃掉。

改成这个样子

1
2
3

pick e7ba81d Commit-1
s 5756e15 Commit-2
s b1b8189 Commit-3

修改完成后 :wq 或者 shift + z + z 退出，进入下一个界面

# This is a combination of 3 commits.
# The first commit's message is:
Commit-1

# This is the 2nd commit message:

Commit-2

# This is the 3rd commit message:

Commit-3

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# Date:      Tue Jan 5 23:27:22 2016 +0800
#
# rebase in progress; onto 5d39ff2
# You are currently editing a commit while rebasing branch 'master' on '5d39ff2'.
#
# Changes to be committed:
#   modified:   a

这里是一个编写 Commit Message 的界面，带 # 的行会被忽略掉，其余的行就会作为新的Commit Message。将这个页面略作修改为：

Commit-1

# Please enter the commit message for your changes. Lines starting
# with '#' will be ignored, and an empty message aborts the commit.
#
# Date:      Tue Jan 5 23:27:22 2016 +0800
#
# rebase in progress; onto 5d39ff2
# You are currently editing a commit while rebasing branch 'master' on '5d39ff2'.
#
# Changes to be committed:
#   modified:   a

保存之后，查看log:

1 2	* 2d7b687 - (HEAD -> master) Commit-1 * 5d39ff2 - Commit-0

最后使用 git push -f 提交

命令行指令

Git 全局设置

1 2	git config --global user.name "mmmwhy" git config --global user.email "mmmwhy@qq.com"

创建新版本库

git clone https://iii.run/mmmwhy/ssql.git
cd seq-annotation
touch README.md
git add README.md
git commit -m "add README"
git push -u origin master

已存在的文件夹或 Git 仓库

cd existing_folder
git init
git remote add origin https://iii.run/mmmwhy/sql.git
git add .
git commit -m "first commit"
git push -u origin master

添加远程

git remote add 命令使用两个参数：

远程命令，如 origin
远程 URL，如 https://github.com/user/repo.git
例如：

$ git remote add iii https://github.com/iii/repo.git
# Set a new remote

$ git remote -v
# Verify new remote
> origin  https://github.com/user/repo.git (fetch)
> origin  https://github.com/user/repo.git (push)
> iii  https://github.com/iii/repo.git (fetch)
> iii  https://github.com/iii/repo.git (push)
