Creating a new hosted git repository:

In order to establish a hosted copy of a git repo:

mkdir <dir>
cd <dir>
git init --bare

Then, in an existing git repo (on the client machine):

git remote add origin <username>@<hostname>:/<dir>
git push origin master

Setting the HEAD reference in git:

git symbolic-ref HEAD refs/heads/{branch name}

This is used to change the default branch when you clone a bare git repository. (Must be run on the server)

Numbers:

10,000,000,000,000,000,000
|  |   |   |   |   |   |hundred
|  |   |   |   |   |thousand
|  |   |   |   |million
|  |   |   |billion
|  |   |trillion
|  |quadrillion
|quintillion

Add User to Group:

This command adds an existing user to an existing group:

usermod -a -G {group} {user}

Create a new User

adduser

is the more advanced option.

usermod -aG sudo <username>

adds the user to the sudoers file.
