修改檔案後，如何提交到git伺服器？

(1)首先需要add，比如.config是被修改的檔案，則

 git add .config

(2)然後執行git commit -m "modify .config for some reason"

(3)然後git push 到git伺服器

(4)更新：git pull

(5)檢視log：git log

如下是全部過程：

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)
