Hi, this post has been written to create a beautiful and useful custom operating system shell setup for developers, data scientists, or everyone who wants to have an unusual Linux,*nix, or macOS shell. This is a completely simple guide for the installation of shell setup for the best efficiency. Install zsh and ohmyzsh ## for Debian/Ubuntu
sudo apt-get install zsh

## for RHEL/Centos/Fedora
sudo yum install zsh
## for only Fedora 
sudo dnf install zsh


## for arch
sudo pacman install zsh
## for mac
brew install zsh The package manager installed the shell on the system. To install ohmyzsh’s latest version: #using curl
sh -c "$(curl -fsSL https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"
#or using wget
sh -c "$(wget https://raw.githubusercontent.com/ohmyzsh/ohmyzsh/master/tools/install.sh -O -)" installed under the directory as hidden. You can see the folder and config files. ohmyzsh will change zsh config file contents. ohmyzsh /home/user .oh-my-zsh .zshrc Change the Theme Open * config file with nano or vim and change themes: .zshrc nano ~/.zshrc
#or
vim ~./zshrc ZSH_THEME="fino-time" You can find different themes on the . pages Install Custom Plugins zsh-autosuggestion git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions zsh-syntax-highlighting git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting zsh-autocomplete git clone --depth 1 -- https://github.com/marlonrichert/zsh-autocomplete.git $ZSH_CUSTOM/plugins/zsh-autocomplete And add these to the plugins tuple in .zshrc plugins = ( git
            sudo
            zsh-autosuggestions 
            zsh-syntax-highlighting 
            zsh-autocomplete
            ) Install pyenv for Python Version Control Pyenv is a tool that can manage python environments and versions. It's a very useful tool for all types of developers. To install the tools: git clone https://github.com/pyenv/pyenv.git ~/.pyenv and to define environment variables: (for zsh) echo 'export PYENV_ROOT="$HOME/.pyenv"' >> ~/.zshrc
echo 'command -v pyenv >/dev/null || export PATH="$PYENV_ROOT/bin:$PATH"' >> ~/.zshrc
echo 'eval "$(pyenv init -)"' >> ~/.zshrc after that: exec "$SHELL" To create python virtual environments, virtualenv plugin installation is required. git clone https://github.com/pyenv/pyenv-virtualenv.git $(pyenv root)/plugins/pyenv-virtualenv Usage You can install many of the python, conda versions with these tools easily. You can check for more information. GitHub repositories ## install a python environment
pyenv install 3.8.5 
## create a virtual environment
pyenv virtualenv 3.8.5 myenv After creating a virtual environment, it's usable with this command: pyenv activate myenv
(myenv)$ Also published here
