很多人問，明明有git gui 和 github可以直接圖形化操作的嗎？全部指令幹啥？？？

呃(⊙o⊙)…呃(⊙o⊙)… ===> 裝逼~

O(∩_∩)O~，開玩笑的，其實就是為了通用和熟悉git，linux裡面照樣這樣用，多熟悉點基礎指令很有用的，

安裝系列：

軟體下載：http://git-scm.com/download/

環境搭建：（比較簡單，看圖）

下面是命令模式，需要一點點linux基礎（Linux基礎學習），沒有也沒事，看詳解

1.我們看看git的配置都有哪些：

git config
————————————————————————————————————————
usage: git config [<options>]

Config file location
--global use global config file
--system use system config file
--local use repository config file
-f, --file <file> use given config file
--blob <blob-id> read config from given blob object

Action
--get get value: name [value-regex]
--get-all get all values: key [value-regex]
--get-regexp get values for regexp: name-regex [value-regex]
--get-urlmatch get value specific for the URL: section[.var] URL
--replace-all replace all matching variables: name value [value_rege x]
--add add a new variable: name value
--unset remove a variable: name [value-regex]
--unset-all remove all matches: name [value-regex]
--rename-section rename section: old-name new-name
--remove-section remove a section: name
-l, --list list all
-e, --edit open an editor
--get-color find the color configured: slot [default]
--get-colorbool find the color setting: slot [stdout-is-tty]

Type
--bool value is "true" or "false"
--int value is decimal number
--bool-or-int value is --bool or --int
--path value is a path (file or directory name)

Other
-z, --null terminate values with NUL byte
--name-only show variable names only
--includes respect include directives on lookup

————————————————————————————————————————
2.設定名字：

git config --global user.name "你的名字"

3.設定郵箱：
git config --global user.email "你的郵箱"

————————————————————————————————————————
4.輸出更顯目的設定
git config --global color.ui auto

5.如果忘記自己的配置，就用這個命令來檢視一下

cat ~/.gitconfig

或者用git命令：git config --list

————————————————————————————————————————
[user]
name = 你的名字
email = 你的郵箱
[color]
ui = auto
————————————————————————————————————————
6.設定SSH Key

ssh-keygen -t rsa -C "你的郵箱"
Generating public/private rsa key pair.
Enter file in which to save the key (/c/Users/DNT_PC/.ssh/id_rsa): 回車一下
/c/Users/DNT_PC/.ssh/id_rsa already exists.
Overwrite (y/n)? 回車一下
————————————————————————————————————————
7.記不得key用這個指令：

$ cat ~/.ssh/id_rsa.pub
————————————————————————————————————————
ssh-rsa AAAAB3NzaC1yc2EAAAADAQABAAABAQD3joLDvLaBHnP4aMJwcjo6gjcipBoOnCzETPkQBu+LdBit8L3CSltQ6AhgOL8xcUHxR+ZojdNhd0XXvOfIfuPJVBH57dqptvAeqDkQHiBE5lX2/7pjPVPHSeTiQd0ijYtc1HxtqMo4U++sR6M7QYXPFnHBogUmZdxItVWr***********************4H2h19aIUImZU2KLndgP1AYGFh1FsprWO0oa6ebsIsPGtgrtHqBfHd9e2yF0/1fIFhidXgGvgmt4K9nO0WJ24vW****************
————————————————————————————————————————
8.在github裡面新增金鑰（公共）

————————————————————————————————————————
9.用手中的私人金鑰和github驗證

ssh -T [email protected]
————————————————————————————————————————
The authenticity of host 'github.com (192.30.252.128)' can't be established.
RSA key fingerprint is SHA256:nThbg6k*************************viKw6E5********.
Are you sure you want to continue connecting (yes/no)? 輸入yes
Warning: Permanently added 'github.com,192.30.252.128' (RSA) to the list of known hosts.
Hi 你的姓名! You've successfully authenticated, but GitHub does not provide shell access.
————————————————————————————————————————
10.在github裡面建立一個公開倉庫（私有的收費）並初始化倉庫（最下面的複選框，最下面的兩個下拉列表後面說）

————————————————————————————————————————
11.複製一份github ssh庫的地址，一會兒有用

————————————————————————————————————————
12.克隆一份到本地

git clone [email protected]:dunitian/test.git（剛才的地址）

————————————————————————————————————————
Cloning into 'test'...
Warning: Permanently added the RSA host key for IP address '192.30.252.131' to the list of known hosts.
remote: Counting objects: 3, done.
remote: Total 3 (delta 0), reused 0 (delta 0), pack-reused 0
Receiving objects: 100% (3/3), done.
Checking connectivity... done.
————————————————————————————————————————
13.寫點東西測試一下

cd test（專案名，注意大小寫）

[email protected]_PC-PC MINGW32 ~/test (master)
ls （檢視當前目錄有哪些東西）
README.md

[email protected]_PC-PC MINGW32 ~/test (master)
vi dnt.txt （如果有dnt.txt的檔案就開啟，沒有就建立一個dnt.txt的檔案）

輸入你想寫的東西，i 進入編輯模式 ，按esc 輸入 :wq 並回車 是儲存
————————————————————————————————————————
14.檢視git的狀態 （沒提交，所以是untracked files狀態）

git status
————————————————————————————————————————
On branch master
Your branch is up-to-date with 'origin/master'.
Untracked files:
(use "git add <file>..." to include in what will be committed)

dnt.txt

nothing added to commit but untracked files present (use "git add" to track)
————————————————————————————————————————
15.把檔案提交到倉庫

git add dnt.txt （新增到暫存區）

git commit -m "add first file to my git" (提交;引號裡面是註釋)
————————————————————————————————————————
[master 4e69105] add first file to my git
warning: LF will be replaced by CRLF in dnt.txt.
The file will have its original line endings in your working directory.
1 file changed, 1 insertion(+)
create mode 100644 dnt.txt
————————————————————————————————————————
16.到github看看，發現這個時候是木有新增我們的檔案的(不要怕)

————————————————————————————————————————
17.檢視提交日記 （嚇死寶寶了，趕緊看看log）

git log
————————————————————————————————————————
commit 4e6910512df341e6d71d83607df8f44a6bd5a5b6
Author: dunitian <[email protected]>
Date: Wed Dec 9 22:26:44 2015 +0800

add first file to my git

commit 6f4fa43de0619c34345fb65d1b32ed887d4efd04
Author: dunitian <[email protected]>
Date: Wed Dec 9 21:30:07 2015 +0800

Initial commit
————————————————————————————————————————
18.原來是要push一下，更新github（如果發現command not found之類的問題再輸入一遍就ok了）

git push
————————————————————————————————————————
warning: push.default is unset; its implicit value has changed in
Git 2.0 from 'matching' to 'simple'. To squelch this message
and maintain the traditional behavior, use:

git config --global push.default matching

To squelch this message and adopt the new behavior now, use:

git config --global push.default simple

When push.default is set to 'matching', git will push local branches
to the remote branches that already exist with the same name.

Since Git 2.0, Git defaults to the more conservative 'simple'
behavior, which only pushes the current branch to the corresponding
remote branch that 'git pull' uses to update the current branch.

See 'git help config' and search for 'push.default' for further information.
(the 'simple' mode was introduced in Git 1.7.11. Use the similar mode
'current' instead of 'simple' if you sometimes use older versions of Git)

Counting objects: 3, done.
Compressing objects: 100% (2/2), done.
Writing objects: 100% (3/3), 294 bytes | 0 bytes/s, done.
