1. 使用git fork一个远程A的代码仓库的副本到自己的远程仓库
在gitlab或者github上面有fork操作按钮
2. 拉取自己的远程仓库到自己的本地
$ git clone https://github.com/xxx/yyy.git
Cloning into 'dingding'...
remote: Counting objects: 52, done.
remote: Compressing objects: 100% (47/47), done.
remote: Total 52 (delta 4), reused 52 (delta 4), pack-reused 0
Receiving objects: 100% (52/52), 1.20 MiB | 40.00 KiB/s, done.
Resolving deltas: 100% (4/4), done.
我第一次clone代码使用的地址是https所以每次push代码都需要输入用户名和密码验证身份 如下：
$ git push origin master
Username for 'https://github.com': xxx@163.com
Counting objects: 5, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (4/4), done.

Total 5 (delta 1), reused 0 (delta 0)
remote: Resolving deltas: 100% (1/1), completed with 1 local object.
To https://github.com/xxx/yyy.git
9623903..ca025de master -> master
为了方便 现在把拉取远程代码的仓库地址换成ssh的
$ git remote set-url git@github.com:xxx/yyy.git // 命令错误
usage: git remote set-url [--push] <name> <newurl> [<oldurl>]
or: git remote set-url --add <name> <newurl>
or: git remote set-url --delete <name> <url>
--push manipulate push URLs
--add add URL
--delete delete URLs
$ git remote set-url --push origin git@github.com:xxx/yyy.git
3. 修改后提交到自己的远程仓库
添加本地修改到暂存区
$ git add --all
warning: LF will be replaced by CRLF in .idea/yyy.iml.
The file will have its original line endings in your working directory.
warning: LF will be replaced by CRLF in .idea/modules.xml.
The file will have its original line endings in your working directory.
warning: LF will be replaced by CRLF in .idea/workspace.xml.
The file will have its original line endings in your working directory.
提交本地修改到本地分支
$ git commit -m "conflict fixed"
[master 26c2de4] conflict fixed
4 files changed, 283 insertions(+), 1 deletion(-)
create mode 100644 .idea/datura_lj.iml
create mode 100644 .idea/modules.xml
create mode 100644 .idea/workspace.xml
查看代码状态
$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
(use "git push" to publish your local commits)
nothing to commit, working tree clean
没有问题后，把本地代码更新到远程仓库
$ git push origin master
Counting objects: 16, done.
Delta compression using up to 4 threads.
Compressing objects: 100% (16/16), done.
Writing objects: 100% (16/16), 4.58 KiB | 0 bytes/s, done.

remote: Resolving deltas: 100% (5/5), completed with 1 local object.
To github.com:xxx/yyy.git
ca025de..5ae59c1 master -> master
拉取A的远程代码
// 先查看下远程代码仓库
$ git remote show origin
* remote origin
Fetch URL: https://github.com/xxx/yyy.git
Push URL: https://github.com/xxx/yyy.git
HEAD branch: master
Remote branch:
master tracked
Local branch configured for 'git pull':
master merges with remote master
Local ref configured for 'git push':
master pushes to master (up to date)
// 添加上游代码仓库
$ git remote add upstream https://github.com/aaa/yyy.git
// 或者使用git remote -v查看远程代码仓库，现在已经添加成功
$ git remote -v
origin https://github.com/xxx/yyy.git (fetch)
origin https://github.com/xxx/yyy.git (push)
upstream https://github.com/Datura900607/datura_lj.git (fetch)
upstream https://github.com/Datura900607/datura_lj.git (push)
// 拉取上游代码仓库的代码
$ git pull upstream master
From https://github.com/aaa/yyy
* branch master -> FETCH_HEAD
Auto-merging readme.txt
CONFLICT (content): Merge conflict in readme.txt
Automatic merge failed; fix conflicts and then commit the result.
xxx@xxx MINGW64 /e/yyy(master|MERGING)
查看代码状态
$ git status
On branch master
Your branch is ahead of 'origin/master' by 1 commit.
(use "git push" to publish your local commits)
You have unmerged paths.
(fix conflicts and run "git commit")
(use "git merge --abort" to abort the merge)
Unmerged paths:
(use "git add <file>..." to mark resolution)
both modified: readme.txt
Changes not staged for commit:
(use "git add <file>..." to update what will be committed)
(use "git checkout -- <file>..." to discard changes in working directory)
modified: .idea/workspace.xml
no changes added to commit (use "git add" and/or "git commit -a")
保存修改的本地代码到缓存区，commit本地代码要写备注
$ git add --all
warning: LF will be replaced by CRLF in .idea/workspace.xml.
The file will have its original line endings in your working directory.
$ git commit -m "fixed form fork"
[master 5ae59c1] fixed form fork
把本地最新代码同步到自己的远程仓库
4. 发送pull request将自己修改的代码合并到A的远程代码仓库
在gitlab或者github上发起pull request 或者new merge request 等待A仓库的管理员进行merge
5. B从A fork一个远程A的代码仓库的副本到B的远程仓库，修改代码后push到B的远程仓库
6. 当我需要同步B的最新代码，拉取B的远程代码到自己的本地
git 命令窗清屏
$ clear
添加B的远程代码仓库，并重命名bbb
$ git remote add bbb https://github.com/bbb/yyy.git
xxx@xxx MINGW64 /e/yyy(master)
// 查看已经 添加成功
$ git remote -v
origin https://github.com/xxx/yyy.git (fetch)
origin git@github.com:xxx/yyy.git (push)
upstream https://github.com/aaa/yyy.git (fetch)
upstream https://github.com/aaa/yyy.git (push)
bbb https://github.com/bbb/yyy.git (fetch)
bbb https://github.com/bbb/yyy.git (push)
从B的远程拉取最新代码 git fetch , git merge
$ git fetch bbb master
remote: Counting objects: 6, done.
remote: Compressing objects: 100% (4/4), done.

7. 关于重置ssh-key
重置ssh-key
$ ssh-keygen -t rsa -C "your github email@163.com"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/xxx/.ssh/id_rsa):
/c/Users/xxx/.ssh/id_rsa already exists.
Overwrite (y/n)? y
Enter passphrase (empty for no passphrase):
Enter same passphrase again:
Your identification has been saved in /c/Users/xxx/.ssh/id_rsa.
Your public key has been saved in /c/Users/xxx/.ssh/id_rsa.pub.
The key fingerprint is:
SHA256:Qg09NpPxBdtL3/n8t4za/ssqgf0mhpPSGePUxIy4ZCs special_yjl@163.com
The key's randomart image is:
