今天學習Git Command-Line Syntax [1] 。
Git command的 convention 為：
`git [switches] <command> [<args>]`
而每一個部分的基本解釋是：
- `git` 是 Git 命令的開頭
- `[switches]` 是可選的選項，可以改變命令的行為
- `<command>` 是想執行的Git命令
- `[<args>]` 是命令的參數
其中常用的git command [2] 有：
add Add file contents to the index
bisect Find by binary search the change that introduced a bug
branch List, create, or delete branches
checkout Checkout a branch or paths to the working tree
clone Clone a repository into a new directory
commit Record changes to the repository
diff Show changes between commits, commit and working tree, etc
fetch Download objects and refs from another repository
grep Print lines matching a pattern
init Create empty git repository or reinitialize an existing one
log Show commit logs
merge Join two or more development histories together
mv Move or rename a file, a directory, or a symlink
pull Fetch from and merge another repository or a local branch
push Update remote refs along with associated objects
rebase Forward-port local commits to the updated upstream head
reset Reset current HEAD to the specified state
rm Remove files from the working tree and from the index
show Show various types of objects
status Show the working tree status
tag Create, list, delete or verify a tag object signed with GPG
而在官方文檔[3]有更完整的解釋。
此外，官方文檔對指令的大分類蠻有意思：
(1) 配置與設定 Setup and Config
(2) 取得和建立項目 Getting and Creating Projects [4]
(3) 基本快照 Basic Snapshotting [5]
(4) 分支與合併 Branching and Merging [6]
(5) 共享與更新項目 Sharing and Updating Projects [7]
(6) 檢查與比較 Inspection and Comparison [8]
(7) 打補丁 Patching
(8) 偵錯 Debugging
(9) 電子郵件 Email
(10) 外部系統 External Systems
(11) 行政 Administration
(12) 伺服器管理 Server Admin
(13) 關道命令 Plumbing Commands
感覺Git 的世界博大精深！要持續去學習。
