Install Oh my bash

Oh My Bash is a delightful community-driven framework for managing your bash configuration, and an auto-update tool so that makes it easy to keep up with the latest updates from the community.

At the end of this blog post, your command line should look similar to the image below:

:inline

In the image:

Blue: indicates a non git based directory/subdirectory
Green: indicates a git based directory in sync with the remote
Orange: indicates a git based directory with changes to be applied

Bash Configuration

Configure Zsh/Bash shell with user based themes to make the command line visually appealing.

Install system fonts

Fonts can be downloaded from here - follow example below to install them on host (install.sh)
NODE_TYPE // text
```
wget https://github.com/Lokaltog/powerline/raw/develop/font/PowerlineSymbols.otf https://github.com/Lokaltog/powerline/raw/develop/font/10-powerline-symbols.conf
sudo mv PowerlineSymbols.otf /usr/share/fonts/
sudo fc-cache -vf
sudo mv 10-powerline-symbols.conf /etc/fonts/conf.d/
```
Note: This configuration can be applied to local terminal setting and also the cloudtop SSH connection.

Package Configuration

Update your machine
NODE_TYPE // text
```
sudo apt -y update && sudo apt -y upgrade
```
Install the powerline fonts
NODE_TYPE // text
```
sudo apt-get install fonts-powerline
```

Install Oh-My-Bash

Install oh-my-bash
NODE_TYPE // bash
```
bash -c "$(curl -fsSL https://raw.githubusercontent.com/ohmybash/oh-my-bash/master/tools/install.sh)"
```
The command line will update to look like below:
Add agnoster theme
NODE_TYPE // text
```
git clone https://github.com/agnoster/agnoster-zsh-theme.git ~/.oh-my-bash/custom/themes/agnoster
```
Make the following amendments in your "~/.bashrc" configuration file and amend the theme to use Agnoster
NODE_TYPE // bash
```
#echo $RANDOM_THEME
#OSH_THEME="font"
OSH_THEME="agnoster"
```
NOTE: If the RANDOM_THEME is set, it will load a random theme each time oh-my-zsh is loaded.
Reload the environment
NODE_TYPE // bash
```
source ~/.bashrc
```
Your command line should now look like below:

NOTE: The command line will now recognize git folders and distinguish between these and normal folders
