git常用命令

1.簡歷github倉庫https://github.com/fulq1234/a.git
2.建立本地倉庫。我在本地新建一個文件夾gitgit，打開文件夾，右鍵選擇git bash here

git init

3.在gitgit下面新建一個文件夾adddd,

git add .

4. git倉庫遷移，git remote更改源

• git remote                                    #不帶參數，列出已經存在的遠程分支
• git remote -v                                 #(-v是–verbose 的簡寫,取首字母)列出詳細信息，在每一個名字後面列出其遠程url
• git remote add [shortname] [url]              #添加遠程倉庫
• git remote rm [shorname]                #刪除git

$ git remote -v

$ git remote add origin https://github.com/fulq1234/a.git

$ git remote -v
origin  https://github.com/fulq1234/a.git (fetch)
origin  https://github.com/fulq1234/a.git (push)

$ git remote add origin2 https://github.com/fulq1234/a.git

$ git remote -v
origin  https://github.com/fulq1234/a.git (fetch)
origin  https://github.com/fulq1234/a.git (push)
origin2 https://github.com/fulq1234/a.git (fetch)
origin2 https://github.com/fulq1234/a.git (push)

$ git remote add origin2 https://github.com/fulq1234/a.git
fatal: remote origin2 already exists.

$ git remote rm origin2

$ git remote add origin2 https://github.com/fulq1234/a.git

$ git remote -v
origin  https://github.com/fulq1234/a.git (fetch)
origin  https://github.com/fulq1234/a.git (push)
origin2 https://github.com/fulq1234/a.git (fetch)
origin2 https://github.com/fulq1234/a.git (push)

5. 拉取遠程倉庫的代碼。
git pull origin master
6.提交本地代碼
git add .
git commit -m ""
git push origin master
7.怎麼解決衝突。如果遠程的一個文件改變了，本地的也改變了。那麼提交代碼會衝突

$ git add .

$ git commit -m "bbb"
[master 908e9a5] bbb
 1 file changed, 2 insertions(+), 1 deletion(-)

$ git push origin master
To https://github.com/fulq1234/a.git
 ! [rejected]        master -> master (fetch first)
error: failed to push some refs to 'https://github.com/fulq1234/a.git'
hint: Updates were rejected because the remote contains work that you do
hint: not have locally. This is usually caused by another repository pushing
hint: to the same ref. You may want to first integrate the remote changes
hint: (e.g., 'git pull ...') before pushing again.
hint: See the 'Note about fast-forwards' in 'git push --help' for details.

方法1：
更新成最新代碼
git pull origin master
再看衝突的那個文件，本地代碼和遠程倉庫的代碼都有。需要修改後提交。

方法2：git stash
$ git stash save "1"
Saved working directory and index state On master: 1

$ git stash list
stash@{0}: On master: 1

$ git stash show
 a.txt | 1 +
 1 file changed, 1 insertion(+)

$ git pull origin master
remote: Enumerating objects: 5, done.
remote: Counting objects: 100% (5/5), done.
remote: Compressing objects: 100% (3/3), done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Unpacking objects: 100% (3/3), done.
From https://github.com/fulq1234/a
 * branch            master     -> FETCH_HEAD
   f01172d..55fa00a  master     -> origin/master
Updating f01172d..55fa00a
Fast-forward
 a.txt | 1 +
 1 file changed, 1 insertion(+)

再看衝突的那個文件，本地代碼和遠程倉庫的代碼都有。需要修改後提交。

$ git stash pop
Auto-merging a.txt
CONFLICT (content): Merge conflict in a.txt

方法3：把衝突文件新建分支，把文件再合併，刪除新建的那個分支

8.多個版本切換
git log 查看歷史記錄
--hard當前版本，--hard^上一個版本。
git reset --hard HEAD

版本切換：
git reset --hard c17177259e63a6f964b27be0a0b1ee6ad4882abd

9.分支
git branch iss53    #建一個分支名字叫iss53
git checkout iss53    #版本切換到分支iss53上面
如果想把master合併到iss53上。
第一步，切換到master 。
git checkout master
第二步，合併iss53
git merge iss53
10.刪除分支
git branch -d hotfix        #刪除分支hotfix
