How to Install Updated fzf on Debian: Command-Line Fuzzy Finder

fzf is a general-purpose command-line fuzzy finder written in Go by Junegunn Choi. It’s an interactive filter program for any kind of list - files, command history, processes, hostnames, bookmarks, git commits, and more. With over 72k GitHub stars, fzf has become an essential tool for command-line productivity and is widely regarded as one of the most useful terminal utilities ever created.

# Add the repository
echo "deb https://debian.griffo.io/apt $(lsb_release -sc 2>/dev/null) main" | sudo tee /etc/apt/sources.list.d/debian.griffo.io.list

Step 2: Update Package Lists

Update your package lists to include the new repository:

sudo apt update

Step 3: Install fzf

Now install the latest version of fzf:

sudo apt install fzf

Step 4: Set Up Shell Integration

Enable fzf’s powerful shell integration features:

# For bash users
echo 'eval "$(fzf --bash)"' >> ~/.bashrc

# For zsh users
echo 'source <(fzf --zsh)' >> ~/.zshrc

# For fish users
echo 'fzf --fish | source' >> ~/.config/fish/config.fish

# Reload your shell configuration
source ~/.bashrc  # or ~/.zshrc

Step 5: Verify Installation

Confirm that fzf is installed and working:

fzf --version

You should see output similar to:

0.65.1 (linux_amd64)

Getting Started with fzf

Now that fzf is installed, let’s explore its powerful features:

Basic Usage

Start with simple file finding:

# Basic file finder
fzf

# Find and edit files
vim $(fzf)

# Find files with preview
fzf --preview 'cat {}'

# Find files with syntax highlighting (requires bat)
fzf --preview 'bat --color=always {}'

Shell Integration Key Bindings

With shell integration enabled, you get these powerful key bindings:

Ctrl-T: Find files and directories - inserts selected items into command line
Ctrl-R: Search command history - fuzzy search through your bash/zsh history
Alt-C: Change directory - fuzzy find and cd into directories

Advanced Usage Examples

Leverage fzf’s power for complex tasks:

# Search and kill processes
ps aux | fzf | awk '{print $2}' | xargs kill

# Interactive git commit browser
git log --oneline | fzf | awk '{print $1}' | xargs git show

# Interactive ripgrep with live reload
rg --color=always --line-number . | fzf --ansi

# Multi-select mode for batch operations
find . -type f | fzf -m

# Search and open files in specific directories
find ~/Documents -type f | fzf --preview 'head -20 {}'

Tool Integrations

fzf works excellently with other modern command-line tools:

# Use with fd for respecting .gitignore
