Basic Linux Setup

Run Ubuntu.

Update Ubuntu

After installing Ubuntu, open the terminal and run the following commands:

sudo apt-get update
sudo apt-get upgrade

Time Sync with Windows 10

After installing Ubuntu in dual boot with Windows 10 , the time is usually messed up in both the systems. The link below provides the details.

Or type the following command in your Ubuntu 16.04 Terminal

timedatectl set-local-rtc 1 --adjust-system-clock

And then set the time on Linux and Windows manually.

NOTE: For lower Ubuntu versions, edit the /etc/default/rcS file.

Install basic tools

Vim:

Vim is a highly configurable text editor. Run the following command in the terminal to install it:

sudo apt-get install vim

Useful for TUI (Terminal User Interface) based debugging.

Git:

Git is a free and open source distributed version control system. To install it:

sudo apt-get install git

Once you've installed Git on your system, you need to configure some of its components before you can use it, such as the username, email address, and the default text editor. This configuration will be a one-time process, and your configured settings should last as long as you don't remove Git from your system.

Create an Identity for Git

To begin with, you first need to set up a default identity (username and email address) for every commit you make on your system. There are two ways to do this. You can either set a global identity so that all the commits you push go through the same identity or set a per-repository identity to use separate identities for different projects.

To set a global identity, open the terminal and run the below commands:

git config --global user.name "your_name"
git config --global user.email "your_email_address"

Configure SSH for Git on Linux

Furthermore, although not necessary, you can also set up SSH for Git on your computer to allow password-less logins. That way, you don't have to enter your password every time you want to commit changes to a repository.

To do this, open a terminal window and run the following command to create a new SSH key with your email:

ssh-keygen -t rsa -b 4096 -C "your_email_address"

When you're prompted to "Enter a file in which to save the key", you can press Enter to accept the default file location. Please note that if you created SSH keys previously, ssh-keygen may ask you to rewrite another key, in which case we recommend creating a custom-named SSH key. To do so, type the default file location and replace id_ssh_keyname with your custom key name.

 Enter a file in which to save the key (/Users/YOU/.ssh/id_ALGORITHM: [Press enter]

The system will now ask you to set a passphrase to add an additional layer of security to SSH on your machine. Type a strong passphrase that you can remember and hit Enter.

Finally, you need to add the SSH key to the ssh-agent, which holds your system's private keys. For this, run the following code in the terminal:

ssh-add ~/.ssh/id

Once you've configured your identity, you can configure Git further to suit your workflow.
