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
http://source.kohlerville.com/2009/02/untrack-files-in-git/
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

git log --graph --oneline --all

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

Creating a tar file:

tar -cvwf file.tar myfile.txt

In the above example, the system would create a tar named file.tar in the directory you currently are in. Wildcards could also be used in this command, for example: tar -cvwf file.tar *.txt would archive all txt files in the current directory.

tar -cvwf home.tar home/

tar -cvf lampp.tar /opt/lampp/

In the above example command the system would create a tar file named home.tar containing the home directory and place that file in the current directory.

unarchive
tar xvf htdocs.tar

gitlab code review

http://www.bloggure.info/work/gitlabhq.html

Once a project created, you can manage it via the rich web interface GitLab offers.
There is :

an integrated issue tracker (without workflow, as simple as the one in github, an issue is open or closed),
a “merge request” section, you can view it as pull requests in github, it allows a developper to notify a reviewer its feature is ready to be merged into another branch (allowing code review),

gitlab

https://github.com/gitlabhq/gitlabhq/blob/stable/doc/installation.md

First 3 steps can be easily skipped with simply install script:

# Install curl and sudo
apt-get install curl sudo

# 3 steps in 1 command :)
curl https://raw.github.com/gitlabhq/gitlab-recipes/master/install/debian_ubuntu.sh | sh

Now you can go to Step 4
Or if you are installing on Amazon Web Services using Ubuntu 12.04 you can do all steps (1 to 6) at once with:

curl https://raw.github.com/gitlabhq/gitlab-recipes/master/install/debian_ubuntu_aws.sh | sh

for more detailed instructions read the HOWTO section of the script

1. Install packages

Keep in mind that sudo is not installed for debian by default. You should install it with as root: apt-get update && apt-get upgrade && apt-get install sudo

sudo apt-get update
sudo apt-get upgrade

sudo apt-get install -y wget curl gcc checkinstall libxml2-dev libxslt-dev sqlite3 libsqlite3-dev libcurl4-openssl-dev libreadline6-dev libc6-dev libssl-dev libmysql++-dev make build-essential zlib1g-dev libicu-dev redis-server openssh-server git-core python-dev python-pip libyaml-dev postfix

# If you want to use MySQL:
sudo apt-get install -y mysql-server mysql-client libmysqlclient-dev

2. Install ruby

wget http://ftp.ruby-lang.org/pub/ruby/1.9/ruby-1.9.3-p194.tar.gz
tar xfvz ruby-1.9.3-p194.tar.gz
cd ruby-1.9.3-p194
./configure
make
sudo make install

3. Install gitolite

Create user for git:

sudo adduser \
  --system \
  --shell /bin/sh \
  --gecos 'git version control' \
  --group \
  --disabled-password \
  --home /home/git \
  git

Create user for gitlab:

# ubuntu/debian
sudo adduser --disabled-login --gecos 'gitlab system' gitlab

Add your user to git group:

sudo usermod -a -G git gitlab

Generate key:

sudo -H -u gitlab ssh-keygen -q -N '' -t rsa -f /home/gitlab/.ssh/id_rsa

Get gitolite source code:

cd /home/git
sudo -H -u git git clone git://github.com/gitlabhq/gitolite /home/git/gitolite

Setup:

sudo -u git sh -c 'echo -e "PATH=\$PATH:/home/git/bin\nexport PATH" >> /home/git/.profile'
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; /home/git/gitolite/src/gl-system-install"
sudo cp /home/gitlab/.ssh/id_rsa.pub /home/git/gitlab.pub
sudo chmod 0444 /home/git/gitlab.pub

sudo -u git -H sed -i 's/0077/0007/g' /home/git/share/gitolite/conf/example.gitolite.rc
sudo -u git -H sh -c "PATH=/home/git/bin:$PATH; gl-setup -q /home/git/gitlab.pub"

Permissions:

sudo chmod -R g+rwX /home/git/repositories/
sudo chown -R git:git /home/git/repositories/

CHECK: Logout & login again to apply git group to your user

# clone admin repo to add localhost to known_hosts
# & be sure your user has access to gitolite
sudo -u gitlab -H git clone git@localhost:gitolite-admin.git /tmp/gitolite-admin

# if succeed  you can remove it
sudo rm -rf /tmp/gitolite-admin

IMPORTANT! If you cant clone gitolite-admin repository - DONT PROCEED INSTALLATION

4. Install gitlab and configuration. Check status configuration.

sudo gem install charlock_holmes --version '0.6.8'
sudo pip install pygments
sudo gem install bundler
cd /home/gitlab
sudo -H -u gitlab git clone -b stable git://github.com/gitlabhq/gitlabhq.git gitlab
cd gitlab

sudo -u gitlab mkdir tmp

# Rename config files
sudo -u gitlab cp config/gitlab.yml.example config/gitlab.yml

Select db you want to use

# SQLite
sudo -u gitlab cp config/database.yml.sqlite config/database.yml

# Or
# Mysql
# Install MySQL as directed in Step #1

# Login to MySQL
$ mysql -u root -p

# Create the gitlabhq production database
mysql> CREATE DATABASE IF NOT EXISTS `gitlabhq_production` DEFAULT CHARACTER SET `utf8` COLLATE `utf8_unicode_ci`;

# Create the MySQL User change $password to a real password
mysql> CREATE USER 'gitlab'@'localhost' IDENTIFIED BY '$password';

# Grant proper permissions to the MySQL User
mysql> GRANT SELECT, INSERT, UPDATE, DELETE, CREATE, DROP, INDEX, ALTER ON `gitlabhq_production`.* TO 'gitlab'@'localhost';

# Exit MySQL Server and copy the example config, make sure to update username/password in config/database.yml
sudo -u gitlab cp config/database.yml.example config/database.yml

Install gems

sudo -u gitlab -H bundle install --without development test --deployment

Setup DB

sudo -u gitlab bundle exec rake gitlab:app:setup RAILS_ENV=production

Setup gitlab hooks

sudo cp ./lib/hooks/post-receive /home/git/share/gitolite/hooks/common/post-receive
sudo chown git:git /home/git/share/gitolite/hooks/common/post-receive

Checking status:

sudo -u gitlab bundle exec rake gitlab:app:status RAILS_ENV=production


# OUTPUT EXAMPLE
Starting diagnostic
config/database.yml............exists
config/gitlab.yml............exists
/home/git/repositories/............exists
/home/git/repositories/ is writable?............YES
remote: Counting objects: 603, done.

Can clone gitolite-admin?............YES
UMASK for .gitolite.rc is 0007? ............YES
/home/git/share/gitolite/hooks/common/post-receive exists? ............YES

If you got all YES - congrats! You can go to next step.

5. Server up

Application can be started with next command:

# For test purposes
sudo -u gitlab bundle exec rails s -e production

# As daemon
sudo -u gitlab bundle exec rails s -e production -d

You can login via web using admin generated with setup:

admin@local.host
5iveL!fe

6. Run resque process (for processing queue).

# Manually
sudo -u gitlab bundle exec rake environment resque:work QUEUE=* RAILS_ENV=production BACKGROUND=yes

# Gitlab start script
sudo -u gitlab ./resque.sh
# if you run this as root /home/gitlab/gitlab/tmp/pids/resque_worker.pid will be owned by root
# causing the resque worker not to start via init script on next boot/service restart

*Ok - we have a working application now. * *But keep going - there are some thing that should be done *

Nginx && Unicorn

Install Nginx

sudo apt-get install nginx

Unicorn

cd /home/gitlab/gitlab
sudo -u gitlab cp config/unicorn.rb.orig config/unicorn.rb
sudo -u gitlab bundle exec unicorn_rails -c config/unicorn.rb -E production -D

Add GitLab to nginx sites & change with your host specific settings

sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/nginx/gitlab -P /etc/nginx/sites-available/
sudo ln -s /etc/nginx/sites-available/gitlab /etc/nginx/sites-enabled/gitlab

# Change **YOUR_SERVER_IP** and **YOUR_SERVER_FQDN**
# to the IP address and fully-qualified domain name
# of the host serving GitLab.
sudo vim /etc/nginx/sites-enabled/gitlab

Restart nginx:

/etc/init.d/nginx restart

Create init script in /etc/init.d/gitlab:

sudo wget https://raw.github.com/gitlabhq/gitlab-recipes/master/init.d/gitlab -P /etc/init.d/

Adding permission:

sudo chmod +x /etc/init.d/gitlab

Gitlab autostart:

sudo update-rc.d gitlab defaults

Now you can start/restart/stop gitlab like:

sudo /etc/init.d/gitlab restart

gitlab ssh key git@localhost's password

https://github.com/gitlabhq/gitlabhq/issues/293#issuecomment-5125487

When you add your users ssh keys to gitlab admin web interface make sure you take the pub key with no carriage return.
