Theming ZSH

I have used

• Tutorial to come up with these commands.
• Start with installing zsh and cloning oh-my-zsh repo.

sudo apt update
sudo apt install zsh -y
sh -c "$(curl -fsSL https://raw.github.com/ohmyzsh/ohmyzsh/master/tools/install.sh)"

Theme Installation

• My personal favourite theme is Powerlevel10k you can choose yours, by going on oh-my-zsh home page.
• You can use the below command

git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/themes/powerlevel10k

• To activate the theme you need to edit your ~/.zshrc file in your personal folder and replace ZSH_THEME=”robbyrussel” with ZSH_THEME=”powerlevel10k/powerlevel10k”.
• You might also like ZSH_THEME="eastwood" if you like simplicity

Plugin Installation

• Lets install zsh-autosuggestion by cloning it inside the plugins folder of .oh.my.zsh.

git clone https://github.com/zsh-users/zsh-autosuggestions ${ZSH_CUSTOM:-~/.oh-my-zsh/custom}/plugins/zsh-autosuggestions

• To enable the auto-suggestion plugin or any other plugins in “zsh”, edit your “~/.zshrc” file in your personal folder.
• Simply change the default line plugins=(git) to plugins=(git zsh-autosuggestions).

Virtual Box SSH setup

• Additionally setting up to ssh into the Virtual Box created system is pretty hectic.
• You can create a port forwarding option in the network settings of your virtual box and edit your host machine’s ssh config as provided in below file.

Host localhost
  HostName localhost
  Port 2222
  User <username>
  PreferredAuthentications publickey
  IdentityFile "/Users/<location of id_rsa>/id_rsa"

• To generate the rsa private and public keys ssh-keygen -t rsa -b 4096
• Add the id_rsa.pub to authorized_keys in the remote .ssh folder. If its not there rename the id_rsa.pub of local system to the authorized_keys also change the permission to 600.
