Oh My Bash and .bashrc file

Next, to make easier work with the bash system let us install the oh-my-bash tool:

$ bash -c "$(curl -fsSL https://raw.githubusercontent.com/ohmybash/oh-my-bash/master/tools/install.sh)"

• make an alias
• export export PATH="/home/username/anaconda/bin:$PATH" or PATH="/home/username/anaconda/bin:$PATH"
• `ln -s``

Install Vim Plugin manager

First we need to install the Vim plugin manager to easily add and remove packages into vim editor. Thus, let us add the plugin.vim:

curl -fLo ~/.vim/autoload/plug.vim --create-dirs \
    https://raw.githubusercontent.com/junegunn/vim-plug/master/plug.vim

Usage

Add a vim-plug section to your ~/.vimrc file:

1. Begin the section with call plug#begin([PLUGIN_DIR])
2. List the plugins with Plug commands
3. call plug#end() to update &runtimepath and initialize plugin system
   • Automatically executes filetype plugin indent on and syntax enable. You can revert the settings after the call. e.g. filetype indent off, syntax off, etc.

Example

call plug#begin()
" The default plugin directory will be as follows:
"   - Vim (Linux/macOS): '~/.vim/plugged'
"   - Vim (Windows): '~/vimfiles/plugged'
"   - Neovim (Linux/macOS/Windows): stdpath('data') . '/plugged'
" You can specify a custom plugin directory by passing it as the argument
"   - e.g. `call plug#begin('~/.vim/plugged')`
"   - Avoid using standard Vim directory names like 'plugin'

" Make sure you use single quotes

" Any valid git URL is allowed
Plug 'https://github.com/junegunn/vim-github-dashboard.git'


" On-demand loading
Plug 'scrooloose/nerdtree', { 'on':  'NERDTreeToggle' }

" Initialize plugin system
call plug#end()

For a better understanding on how to use the Vim Plugin manager visit the git webpage.

The .vimrc file

Next you will see the contents of the vimrc file in this repository:

let g:airline_symbols.colnr = ' ㏇:'

after copy and paste, or added the require code call the plug installer by entering on command mode in Vim (pressing Esc key), then, call :PlugInstall to update and install the new Plugins.
