過程 181.1. Git

  1. install

    sudo apt-get install git-core
    			
  2. config

    			
    $ git-config --global user.name neo
    $ git-config --global user.email openunix@163.com
    			
    			
  3. Initializ

    $ mkdir repository
    $ cd repository/
    
    /repository$ git-init-db
    Initialized empty Git repository in .git/
    			

    to check .gitconfig file

    $ cat ~/.gitconfig
    [user]
            name = chen
            email = openunix@163.com
    			

181.1. Repositories 倉庫管理

181.1.1. initial setup

Tell git who you are:

$ git config user.name "FirstName LastName"
$ git config user.email "user@example.com"

If you have many git repositories under your current user, you can set this for all of them


$ git config --global user.name "FirstName LastName"
$ git config --global user.email "user@example.com"

If you want pretty colors, you can setup the following for branch, status, and diff commands:

$ git config --global color.branch "auto"
$ git config --global color.status "auto"
$ git config --global color.diff "auto"

Or, to turn all color options on (with git 1.5.5+), use:

$ git config --global color.ui "auto"
To enable aut-detection for number of threads to use (good for multi-CPU or multi-core computers) for packing repositories, use:


$ git config --global pack.threads "0"
To disable the rename detection limit (which is set "pretty low" according to Linus, "just to not cause problems for people who have less memory in their machines than kernel developers tend to have"), use:

$ git config --global   diff.renamelimit "0"
		

181.1.2. checkout

將 nqp-cc/src/QASTCompilerMAST.nqp 檔案 重置到 211ab0b19f25b8c81685a97540f4b1491eb17504 版本

git checkout 211ab0b19f25b8c81685a97540f4b1491eb17504 -- nqp-cc/src/QASTCompilerMAST.nqp
		

181.1.3. Creating and Commiting

$ cd (project-directory)
$ git init
$ (add some files)
$ git add .
$ git commit -m 'Initial commit'
		

181.1.4. Manager remote

remote add

		
git remote add origin git@localhost:example.git
		
		

remote show

		
git remote show
origin
		
		

remote rm

		
git remote rm origin
		
		

添加多個遠程倉庫

git remote add origin git@localhost:example.git
git remote add another https://gitcafe.com/netkiller/netkiller.gitcafe.com.git
git push origin master
git push another master
		

181.1.5. Status

#
no changes added to commit (use "git add" and/or "git commit -a")
		
		

181.1.6. Diff

		
neo@neo-OptiPlex-380:~/tmp/example$ git diff
diff --git a/test1 b/test1
index e69de29..ce01362 100644
--- a/test1
