Why You Might Use fzf with fd—and Beyond

At first glance, fzf looks like a simple fuzzy finder for your terminal. You type part of a string, and it finds the best matches in a list. That alone is powerful—but not enough. To use fzf effectively, you need to feed it good data. That’s where tools like fd come in.

The Role of fd: Clean Input for Better Output

fd is a modern replacement for find. It's faster, more intuitive, and designed to work well with other command-line tools. While fzf handles fuzzy selection, fd generates the list of items you can select from. This separation of concerns is critical.

Compare:

fzf

This opens fzf with no input. It waits for something to search. You can type, but it does nothing useful.

Now:

fd . | fzf

fd recursively lists all files from the current directory. fzf then allows you to quickly pick the one you want. Together, they create an interactive file navigation system that’s faster and more flexible than a GUI.

Real World: Beyond File Navigation

The power of fzf extends far beyond picking files:

1. Git Workflow Enhancement

git checkout $(git branch | fzf)

Quickly switch branches without remembering exact names.

2. Command History Search

history | fzf

Find a previously used command without paging through history.

3. Process Management

ps aux | fzf | awk '{print $2}' | xargs kill

Fuzzy-select a process to kill without manually finding the PID.

4. SSH Host Selection

cat ~/.ssh/known_hosts | cut -d',' -f1 | fzf | xargs ssh

Choose a remote host to connect to from your known SSH entries.

5. Running Scripts

ls ~/scripts | fzf | xargs -I{} bash ~/scripts/{}

Select a script to execute from a collection.

6. Systemd Service Control

systemctl list-units --type=service --all | fzf | awk '{print $1}' | xargs systemctl restart

Interactively restart a systemd service.

Why Pairing Matters

fzf alone is an interface. What makes it useful is your data source. The better your source list, the more powerful your workflow. fd, git, ps, ls, systemctl, and even cat can be used as upstream providers to create dynamic, contextual interfaces with minimal overhead.

Use fzf as a control mechanism: a selector for lists you define. Then pipe the output into whatever action you want to take.

Summary

  • fzf is a universal interface for selecting from a list.
  • fd is a fast, modern file generator—perfect as input to fzf.
  • The pairing allows efficient, focused file management.
  • Outside of files, fzf improves speed, clarity, and precision in virtually every shell task involving lists.

If you ever find yourself repeating grep or cat into awk to get a list just to copy and paste something—consider using fzf instead.
