Setup Instructions


Backup your existing configuration:

cp ~/.zshrc ~/.zshrc.backup

Create the new configuration:

# Copy the configuration above to your ~/.zshrc file
vim ~/.zshrc
# Paste the configuration and save

Install FZF key bindings:

$(brew --prefix)/opt/fzf/install

Apply the configuration:

source ~/.zshrc
Optional: Install Powerlevel10k Theme

For an even better visual experience:
# Install Powerlevel10k
git clone --depth=1 https://github.com/romkatv/powerlevel10k.git ${ZSH_CUSTOM:-$HOME/.oh-my-zsh/custom}/themes/powerlevel10k

# Update ZSH_THEME in ~/.zshrc
sed -i '' 's/ZSH_THEME="robbyrussell"/ZSH_THEME="powerlevel10k\/powerlevel10k"/' ~/.zshrc

# Reload zsh
source ~/.zshrc

# Follow the configuration wizard that appears
p10k configure

Smart aliases: Shorter commands for common operations
The Fuck: Type fuck after a failed command to get corrections

Enhanced Commands


ls → eza: Better file listing with icons
cat → bat: Syntax highlighting for file viewing
grep → ripgrep: Faster searching through files

Useful Functions


mkd <dir>: Create and enter directory
extract <file>: Extract any archive type
backup <file>: Quick timestamped backup
search <term>: Search files with preview
killport <port>: Kill process using specific port
weather [location]: Get weather report

Navigation Shortcuts


.., ..., ....: Go up directories
-: Go to previous directory
Auto-cd: Type directory name to cd into it

Customization Tips


Add custom aliases: Add them to the aliases section or create ~/.zshrc.local
Change theme: Modify ZSH_THEME variable
Add plugins: Add to the plugins array
Modify prompt: Use Powerlevel10k for extensive customization

Troubleshooting


Slow startup: Comment out unused plugins
Font issues: Install and set Nerd Font in terminal preferences
Command not found: Ensure Homebrew paths are correct
Permission issues: Check file permissions with ls -la ~/.zshrc

This configuration provides a modern, feature-rich terminal experience that will significantly boost your productivity!
