dotfiles

Minimal dotfiles for Ubuntu VMs with zsh, tmux, and Oh-My-Zsh configuration.

Features

• zsh as default shell with:
  • Oh-My-Zsh framework
  • Syntax highlighting
  • Auto-suggestions
  • Command correction
• tmux with:
  • Ctrl+a as prefix key
  • Mouse support
  • Vi mode
  • Easy config reload (prefix + r)
• Auto-switch from bash to zsh (appended to existing .bashrc)
• Automatic backup of existing dotfiles

Installation

git clone <your-repo-url> ~/dotfiles
cd ~/dotfiles
chmod +x install.sh
./install.sh

What it does

1. Backs up existing dotfiles to ~/.dotfiles_backup_<timestamp>
2. Installs zsh, tmux, and required plugins
3. Installs Oh-My-Zsh framework
4. Creates symlinks for configuration files
5. Modifies .bashrc to auto-switch to zsh on login

Files

• install.sh - Installation script
• zshrc - Zsh configuration
• tmux.conf - Tmux configuration

How it handles .bashrc

The installer preserves your existing .bashrc and appends a small snippet that:

• Automatically switches to zsh when you log in
• Only switches if zsh is installed and available
• Won't add duplicate entries if you run the installer multiple times

No need to change your default shell with chsh - the auto-switch handles everything!

Post-installation

After installation, either:

• Log out and log back in, or
• Run exec zsh to start using zsh immediately
