How to mkdir only if a dir does not already exist

reference url:
http://stackoverflow.com/questions/793858/how-to-mkdir-only-if-a-dir-does-not-already-exist

Try mkdir -p:

mkdir -p foo

Note that this will also create any intermediate directories that don't exist; for instance,

mkdir -p foo/bar/baz

will create directories foo, foo/bar, and foo/bar/baz if they don't exist.

git rename branch
http://fredchiu.wordpress.com/2011/12/28/%E9%87%8D%E6%96%B0%E5%91%BD%E5%90%8D-rename-git-branch/
假設現在有兩個 branch， master 跟 old-branch ，目前在 master ，想要把 old-branch 的名字改成 new-branch 的話，請輸入：

git branch -m old-branch new-branch

如果現在已經在 old-branch ，想要直接把名字改成 new-branch 的話，就輸入：

git branch -m new-branch

git orphan

http://stackoverflow.com/questions/5086833/how-to-create-a-branch-without-adding-all-the-existing-files

git checkout --orphan branchname
git rm -rf .

After doing that you can create, add, and commit new files and the resulting branch will have no common history with any other branches in your project (unless you merge them at some point).

git untrack

The following command will stop tracking but keep the file there intact.
git rm --cached filename

不小心修改到檔案，但卻不知道改到哪些檔案，與最後的 commit 比較，顯示修改過的檔案清單，請輸入以下指令
git diff --stat

Cherry picking a range of commits
http://ariejan.net/2010/06/10/cherry-picking-specific-commits-from-another-branch
In some cases picking one single commit is not enough. You need, let's say three consecutive commits. cherry-pick is not the right tool for this. rebase is. From the previous example, you'd want commit 76cada and 62ecb3 in master.
The flow is to first create a new branch from feature at the last commit you want, in this case 62ecb3.

git checkout -b newbranch 62ecb3

Next up, you rebase the newbranch commit --onto master. The 76cada^ indicates that you want to start from that specific commit.

git rebase --onto master 76cada^

The result is that commits 76cada through 62ecb3 are applied to master.

強制更改 server 上的 branch 舊有的提交歷史，指定將 server 上特定 branch ( e.g. develop)的提交歷史紀錄，強制覆寫為本機 branch ( e.g. develop)的提交歷史紀錄
需具備該權限，才能正常執行操作
git push origin develop -f

恢復 Commit，重新提交 Commit

假如今天您修改了兩個檔案，並且新增到暫存區了，狀態如下：

# On branch master
# Changes to be committed:
#   (use "git reset HEAD <file>..." to unstage)
#
#       modified:   Makefile
#       modified:   user/easy_setup/easysetup.h
#

並且已經執行了 git commit -m “first commit”，發現訊息寫錯想要修改，可以透過 reset 方式來做，請先用 git log 方式查看訊息

git log --stat

commit c13eb41110a38ef7145bb8815560641697800659
Author: appleboy <appleboy.tw at gmail.com>
Date:   Fri Aug 20 20:02:55 2010 +0800

    first commit

 Makefile                    |   10 ++-
 user/easy_setup/easysetup.h |  157 ++++++++++++++++++++-----------------------
 2 files changed, 79 insertions(+), 88 deletions(-)

這要怎麼解決才可以改變此訊息呢？

git reset --soft HEAD^

這是一個大家常用的作法，假如您想要修改 commit 訊息，或者是尚未修改好檔案，下完此指令，您會發現 reset 會幫忙把舊的 head 複製到 .git/ORIG_HEAD，如果您沒有想要重新建立 commit 訊息，您可以下

git commit -a -c ORIG_HEAD

git 會跳出剛剛的 first commit 讓您來修改，或者是自己用 git commit -m “XXXXXXX” 這樣也可以喔。

取消最後一次 commit ，提交紀錄及檔案都還原成倒數第二次 commit 的狀態

強制恢復到上一版本

上面是介紹恢復 commit 訊息，之前修改過的檔案還會存在，底下會使用 reset hard 的方式恢復到上一版本，上一版本跟此版本之間所修改的檔案，將不會存檔，git reset 參數之一 –hard

git reset --hard HEAD~3

這指令意思是說，最後三個版本 (HEAD, HEAD^, and HEAD~2) 都不是您想要修改的，你也不想給其他人看見這三個版本資訊，如果您想要保存修改過的檔案，請勿下此指令
