Installing fzf on Linux

1. Via Package Manager

During installation, enable shell extensions (keybindings and autocompletion) for maximum utility. Restart your shell or source your profile (e.g., source ~/.bashrc).

Example: On an ava.hosting VPS, install fzf via GitHub to search through project files in /var/www/html effortlessly.

Core Use Cases of fzf

1. File Finder

Run:

fzf

This opens an interactive list of files and directories in your current folder, filterable in real-time.

2. Integrate with find

Search for files:

find . -type f | fzf

3. Use with rg (ripgrep)

For faster file searches:

rg --files | fzf

Example: Use rg --files | fzf on your ava.hosting server to locate a specific config file in a crowded /etc directory.

4. Search Command History

Find and reuse past commands:

history | fzf

5. Git Integration

View Git commit logs:

git log --oneline | fzf

Switch branches:

git checkout $(git branch | fzf)

Custom Keybindings & Shortcuts

If you enabled keybindings during installation, use:

  • Ctrl-T: Paste selected file paths at the cursor.
  • Ctrl-R: Search and execute command history.
  • Alt-C: Change directories interactively.

These shortcuts speed up navigation and command recall on your ava.hosting server.

Customizing fzf

Enhance fzf’s appearance and functionality by adding to your .bashrc or .zshrc:

export FZF_DEFAULT_OPTS="
  --height 40%
  --layout=reverse
  --border
  --preview 'bat --style=numbers --color=always --line-range :500 {}'
"

This creates a sleek interface with file previews using bat.

Powerful Integrations

Combine fzf with:

  • tmux: Open selections in new panes or windows.
  • fd/rg: Accelerate file discovery.
  • nnn/lf/ranger: Enhance terminal file managers.
