Git 基本操作
1.创建仓库
——创建工作目录（Working Directory）：git三种副本：工作目录（Working Direcotry），暂存区域（Stage，索引（Index）），仓库（History）
#/home/yang/Documents/repo01
. ├── datafiles │ └── data.txt ├── test01 ├── test02 └── test03
# Initialize the local Git repository（在根目录下生成.git文件夹） git init
2.查看文件状态
yang@mint-linux ~/Documents/repo01 $ git status # On branch master # # Initial commit # # Untracked files: # (use "git add <file>..." to include in what will be committed) # # datafiles/ # test01 # test02 # test03 nothing added to commit but untracked files present (use "git add" to track)
3.添加文件
——git add files 把当前文件放入暂存区域
yang@mint-linux ~/Documents/repo01 $ git add . yang@mint-linux ~/Documents/repo01 $ git status # On branch master # # Initial commit # # Changes to be committed: # (use "git rm --cached <file>..." to unstage) # # new file: datafiles/data.txt # new file: test01 # new file: test02 # new file: test03 #
3.提交文件
——git commit 给暂存区域生成快照并提交。
yang@mint-linux ~/Documents/repo01 $ git commit -m "Initial commit" [master (root-commit) 3f79459] Initial commit 4 files changed, 4 insertions(+) create mode 100644 datafiles/data.txt create mode 100644 test01 create mode 100644 test02 create mode 100644 test03 yang@mint-linux ~/Documents/repo01 $ git status # On branch master nothing to commit, working directory clean
4.查看文件内容变更
yang@mint-linux ~/Documents/repo01 $ echo "This is a change" > test01 yang@mint-linux ~/Documents/repo01 $ echo "and this is another change" > test02 yang@mint-linux ~/Documents/repo01 $ git diff diff --git a/test01 b/test01 index 749eb2d..d0a432b 100644 --- a/test01 +++ b/test01 @@ -1,4 +1 @@ -datafiles -test01 -test02 -test03 +This is a change diff --git a/test02 b/test02 index e69de29..552c22e 100644 --- a/test02 +++ b/test02 @@ -0,0 +1 @@ +and this is another change
yang@mint-linux ~/Documents/repo01 $ git commit -a -m "These are new changes"
5.查看工作目录提交记录
（回顾:git status--查看文件状态，git-diff--查看文件内容状态）
# Make some changes in the file echo "This is a new change" > test01 echo "and this is another new change" > test02
yang@mint-linux ~/Documents/repo01 $ git status
# On branch master
# 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: test01
# modified: test02
#
no changes added to commit (use "git add" and/or "git commit -a")
yang@mint-linux ~/Documents/repo01 $ git diff
diff --git a/test01 b/test01

6.删除文件
如果你删除了一个在版本控制之下的文件，那么使用git add .不会在索引中删除这个文件。需要通过带-a选项的git commit命令和-A选项的git add命令来完成
# Create a file and put it under version control touch nonsense.txt git add . && git commit -m "a new file has been created" # Remove the file rm nonsense.txt # Try standard way of committing -> will not work git add . && git commit -m "a new file has been created" # Now commit with the -a flag git commit -a -m "File nonsense.txt is now removed" # Alternatively you could add deleted files to the staging index via git add -A . git commit -m "File nonsense.txt is now removed"
7.更正提交的信息
git commit --amend -m "More changes - now correct"
