#c #discuss

Hi, This post has been written to create a beautiful and useful custom operating system shell setup for developers, data scientists or everyone who want to have unusual linux,*nix or macos shell. This is completely simple guide for installation of shell setup for 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
Enter fullscreen mode Exit fullscreen mode

The package manager installed the shell on the system.

to install ohmyzsh 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 -)"
Enter fullscreen mode Exit fullscreen mode

ohmyzsh installed under the /home/user directory as hidden. You can see the folder .oh-my-zsh and .zshrc config files. ohmyzsh will change zsh config file contents.

change the theme

Open .zshrc* config file with nano or vim and change themes:

nano ~/.zshrc #or vim ~./zshrc
Enter fullscreen mode Exit fullscreen mode 
ZSH_THEME="fino-time"
Enter fullscreen mode Exit fullscreen mode

You can find different themes from the pages

git clone https://github.com/zsh-users/zsh-autosuggestions.git $ZSH_CUSTOM/plugins/zsh-autosuggestions
Enter fullscreen mode Exit fullscreen mode

zsh-syntax-highlighting 

git clone https://github.com/zsh-users/zsh-syntax-highlighting.git $ZSH_CUSTOM/plugins/zsh-syntax-highlighting
