Fzf Fuzzy Finder

# fzf - Fuzzy Finder

Interactive command-line fuzzy finder with powerful integration capabilities.

## Basic Usage

### Simple filtering ```bash # Pipe list to fzf ls | fzf

# Select file find . -type f | fzf

# Multi-select (Tab to select, Shift+Tab to deselect) ls | fzf -m

# Preview files while selecting ls | fzf --preview 'cat {}'

# With bat for syntax highlighting ls | fzf --preview 'bat --color=always {}' ```

### Shell integration ```bash # After installing, add to ~/.bashrc or ~/.zshrc: # source /path/to/fzf/shell/completion.bash # source /path/to/fzf/shell/key-bindings.bash

# Key bindings: # Ctrl+R - Command history # Ctrl+T - File search # Alt+C - Directory navigation

# Use in command line vim **<TAB> # File completion cd **<TAB> # Directory completion kill -9 **<TAB> # Process completion ```

## Common Patterns

### File selection ```bash # Open file in vim vim $(fzf)

# Edit with preview vim $(fzf --preview 'bat --color=always --line-range :500 {}')

# Select and copy fzf | xargs -I {} cp {} /destination/

# Delete selected files fzf -m | xargs rm ```

### Directory navigation ```bash # CD to selected directory cd $(find . -type d | fzf)

# Alias for quick nav alias cdf='cd $(find . -type d | fzf)'

# Or use Alt+C keybinding ```

### Git integration ```bash # Checkout branch git branch | fzf | xargs git checkout

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

# Add files interactively git status -s | fzf -m | awk '{print $2}' | xargs git add

# Fuzzy git log browser alias gll='git log --oneline | fzf --preview "git show {1}"' ```

### Process management ```bash # Kill process ps aux | fzf | awk '{print $2}' | xargs kill

# Kill multiple processes ps aux | fzf -m | awk '{print $2}' | xargs kill -9 ```

## Advanced Features

### Preview window ```bash # Preview on the right fzf --preview 'cat {}'

# Preview position and size fzf --preview 'cat {}' --preview-window=right:50%

# Preview with bat fzf --preview 'bat --color=always --style=numbers --line-range=:500 {}'

# Toggle preview with Ctrl+/ fzf --preview 'cat {}' --bind 'ctrl-/:toggle-preview'

# Preview directory contents find . -type d | fzf --preview 'ls -la {}' ```

### Custom key bindings ```bash # Execute action on selection fzf --bind 'enter:execute(vim {})'

# Multiple bindings fzf --bind 'ctrl-e:execute(vim {})' \ --bind 'ctrl-o:execute(open {})'

# Reload on key press fzf --bind 'ctrl-r:reload(find . -type f)'

# Accept non-matching input fzf --print0 --bind 'enter:print-query' ```

### Filtering options ```bash # Case-insensitive (default) fzf -i

# Case-sensitive fzf +i

# Exact match fzf -e

# Inverse match (exclude) fzf --query='!pattern'

# OR operator fzf --query='py$ | js$' # .py or .js files

# AND operator fzf --query='test .py' # Contains both 'test' and '.py' ```

## Integration Examples

### With ripgrep ```bash # Search content and open in vim rg --line-number . | fzf | awk -F: '{print "+"$2, $1}' | xargs vim

# Search and preview matches rg --line-number . | fzf --delimiter : \ --preview 'bat --color=always {1} --highlight-line {2}' \ --preview-window +{2}-/2 ```

### With fd ```bash # Find and preview files fd --type f | fzf --preview 'bat --color=always {}'

# Find files modified today fd --changed-within 1d | fzf --preview 'bat {}' ```

### With docker ```bash # Select and enter container docker ps | fzf | awk '{print $1}' | xargs -I {} docker exec -it {} bash

# Remove selected images docker images | fzf -m | awk '{print $3}' | xargs docker rmi

# View logs docker ps | fzf | awk '{print $1}' | xargs docker logs -f ```

### With kubectl ```bash # Select pod kubectl get pods | fzf | awk '{print $1}' | xargs kubectl describe pod

# Get logs kubectl get pods | fzf | awk '{print $1}' | xargs kubectl logs -f

# Delete pods kubectl get pods | fzf -m | awk '{print $1}' | xargs kubectl delete pod ```

## Useful Aliases

Add to your shell config:

```bash # Fuzzy file search and open in vim alias fv='vim $(fzf --preview "bat --color=always --style=numbers {}")'

# Fuzzy directory change alias fcd='cd $(find . -type d | fzf)'

# Fuzzy git checkout alias gco='git branch | fzf | xargs git checkout'

# Fuzzy process kill alias fkill='ps aux | fzf | awk "{print \$2}" | xargs kill -9'

# Fuzzy history search (Ctrl+R is built-in) alias fh='history | fzf | awk "{print \$2}" | xargs -I {} sh -c "{}"'

# Find and edit alias fe='fd --type f | fzf --preview "bat --color=always --style=numbers {}" | xargs -r $EDITOR' ```

## Configuration

### Environment variables ```bash # Default options export FZF_DEFAULT_OPTS=' --height 40% --layout=reverse --border --inline-info --preview "bat --style=numbers --color=always --line-range :500 {}" '

# Use fd instead of find export FZF_DEFAULT_COMMAND='fd --type f --hidden --follow --exclude .git'

# For Ctrl+T export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"

# For Alt+C export FZF_ALT_C_COMMAND='fd --type d --hidden --follow --exclude .git' ```

### Color scheme ```bash export FZF_DEFAULT_OPTS=' --color=bg+:#313244,bg:#1e1e2e,spinner:#f5e0dc,hl:#f38ba8 --color=fg:#cdd6f4,header:#f38ba8,info:#cba6f7,pointer:#f5e0dc --color=marker:#f5e0dc,fg+:#cdd6f4,prompt:#cba6f7,hl+:#f38ba8 ' ```

## Advanced Workflows

### Project file browser ```bash # Smart file browser with preview fzf \ --preview 'bat --color=always --style=numbers --line-range=:500 {}' \ --preview-window='right:60%:wrap' \ --bind 'enter:execute(vim {})' \ --bind 'ctrl-y:execute-silent(echo {} | pbcopy)+abort' \ --header 'Enter: edit | Ctrl+Y: copy path' ```

### Multi-purpose search ```bash # Search in files and navigate to line rg --line-number --no-heading . | \ fzf --delimiter=: \ --preview 'bat --color=always --style=numbers --highlight-line {2} {1}' \ --preview-window='+{2}-/2' \ --bind 'enter:execute(vim {1} +{2})' ```

### Docker container manager ```bash #!/bin/bash # docker-fzf.sh container=$(docker ps --format "table {{.Names}}\t{{.Status}}\t{{.Image}}" | fzf --header-lines=1 | awk '{print $1}') if [ -n "$container" ]; then docker exec -it "$container" bash fi ```

## Tips

- Use `--preview` for visual context - Combine with `bat`, `rg`, `fd` for powerful workflows - Press `?` in fzf to see keybindings - Use `Tab` for multi-select - `Ctrl+/` to toggle preview (if bound) - `Ctrl+K` / `Ctrl+J` to navigate - Start query with `'` for exact match - Start with `!` to exclude - Use `|` for OR, space for AND - Set `FZF_DEFAULT_OPTS` for persistent config

## Performance

```bash # For large file lists, use fd or rg export FZF_DEFAULT_COMMAND='fd --type f'

# Limit depth for faster results export FZF_DEFAULT_COMMAND='fd --type f --max-depth 5'

# Use parallel preview fzf --preview 'bat {}' --preview-window 'hidden' ```
