<span>GIT在Linux上的安装和使用简介

解压后切换到其目录
$ tar xvfj git</span>-1.7.6.tar.<span>bz2
$ cd git</span>-1.7.6<span>
 
使用默认配置进行安装，如果想修改配置，可以使用 </span>./configure --<span>help 来获取帮助
 
$ </span>./<span>configure
$ make
$ make install
 
</span>2<span>、初始化配置
GIT默认安装在 </span>/usr/local/<span>bin ，安装之后可以验证一下是否安装好
 
$ whereis git
git</span>: /usr/local/bin/<span>git
$ git  </span>--<span>version
git version </span>1.7.6<span>
$ git  </span>--<span>help
 
首先需要指定用户名和电子邮件地址
 
$ git config  </span>--<span>global</span> user.<span>name &ldquo;GIT Admin&rdquo;
$ git config  </span>--<span>global</span> user.emal obugs.net@gmail.<span>com
 
再验证一下配置信息
  www</span>.2cto.<span>com  
$ git config  </span>--<span>list</span><span>
user</span>.name=<span>GIT Admin
user</span>.email=obugs.net@gmail.<span>com
core</span>.repositoryformatversion=0<span>
core</span>.filemode=<span>true</span><span>
core</span>.bare=<span>false</span><span>
core</span>.logallrefupdates=<span>true</span><span>
 
其实这些配置是存放在个人主目录下的 </span>.<span>gitconfig 文件中的
 
$ cat </span>~/.<span>gitconfig
[user]
name </span>=<span> GIT Admin
email </span>= obugs.net@gmail.<span>com
 
</span>3<span>、建立工程
本地存储的任何一个目录都可以建立GIT工程，如果已有工程位于 </span>/home/obugs/projects/<span>orangebugs 目录，就可以把这目录定义为GIT工程
$ cd </span>/home/obugs/projects/<span>orangebugs
$ git init
Initialized </span><span>empty</span> Git repository in /home/obugs/projects/orangebugs/.git/<span>
 
这样就建立了一个名为 </span>.<span>git 的文件夹，这就是GIT用来存储信息和跟踪改动的文件夹。
  www</span>.2cto.<span>com  
$ ls </span>-altr .<span>git
total </span>40<span>
drwxrwxr</span>-x 4 git git 4096 Aug 13 22:39<span> refs
drwxrwxr</span>-x 4 git git 4096 Aug 13 22:39<span> objects
drwxrwxr</span>-x 2 git git 4096 Aug 13 22:39<span> info
drwxrwxr</span>-x 2 git git 4096 Aug 13 22:39<span> hooks
</span>-rw-rw-r -- 1 git git 23 Aug 13 22:39<span> HEAD
</span>-rw-rw-r -- 1 git git 73 Aug 13 22:39<span> description
</span>-rw-rw-r -- 1 git git 92 Aug 13 22:39<span> config
drwxrwxr</span>-x 2 git git 4096 Aug 13 22:39<span> branches
drwxrwxr</span>-x 36 git git 4096 Aug 13 22:39 ..<span>
drwxrwxr</span>-x 7 git git 4096 Aug 13 22:39 .
 
4<span>、向工程添加和提交文件
这些动作和CVS、SVN等操作类似
 
$ git add </span>*.java *.<span>c
$ git commit </span>-<span>m &lsquo;Initial upload of the project&rsquo;
create mode </span>100755 Orangebugs.<span>java
create mode </span>100755 pwm/ui/DataManager.<span>java
create mode </span>100755 pwm/ui/PasswordFrame.<span>java
create mode </span>100755 pwm/tools/StrongEncryption.<span>java
create mode </span>100755 pwm/tools/PasswordStrength.<span>java
</span>..<span>
 
注意如果之前没有使用 git config 指定用户名和电子邮件地址，这里会报错
$ git commit </span>-m &lsquo;Initial upload of the project'<span>
 
*** Please tell me who you are.
  www.2cto.com  
Run
 
git config  --global user.email &ldquo;you@example.com&rdquo;
git config  --global user.name &ldquo;Your Name&rdquo;
 
to set your account&rsquo;s default identity.
Omit  --global to set the identity only in this repository.
 
fatal: empty ident not allowed
 
5、更改文件和提交改动
编辑文件、添加或者删除了一些字段
$ vi Orangebugs.java
 
查看和GIT仓库中的文件相比有了那些改动
 
$ git diff
diff  --git a/Orangebugs.java b/Orangebugs.java
index 6166ed1..fd82d32 100644
&mdash; a/Orangebugs.java
+++ b/Orangebugs.java
@@ -2,7 +2,7 @@
- public counter=10
+ public counter=55
 
如果要提交，需要先确保将文件添加到了临时区域(staging area)然后才能提交，提交时会自动打开系统的默认编辑器，用户添加一些注释后保存并退出编辑器的时候，这些注释就同时提交到仓库中去了
  www.2cto.com  
$ git add Orangebugs.java
$ git commit
[master 80f10a9] Added password strength meter functionality
1 files changed, 56 insertions(+), 7 deletions(-)
或者，简单一点的方法是使用 git commit -a 把上面两个命令合二为一。
6、查看状态和查看注释
如果本地的文件和远端GIT仓库上的文件相比没有任何改动，则
 
$ git status
# On branch master
nothing to commit (working directory clean)
 
如果本地做了改动但是没有提交，则
 
$ git status
# On branch master
# Changes not staged for commit:
# (use &ldquo;git add &hellip;&rdquo; to update what will be committed)
# (use &ldquo;git checkout &mdash; &hellip;&rdquo; to discard changes in working directory)
#
# modified: Orangebugs.java
#
no changes added to commit (use "git add" and/or "git commit -a")
 
另外，可以用下面的命令查看文件历史和以往的注释
 
$ git log Orangebugs.java
