fzf

fzf is a command line fuzzy finder. It can search through the entries in a list of files, command history, processes, hostnames, bookmarks, git commits, etc.

fzf provides 3 keyboard shortcuts:

Ctrl-t

Paste the selected files and directories onto the command-line.

By default, fzf uses find to search for files. This can be re-configured by setting FZF_CTRL_T_COMMAND in .bashrc/.zshrc:

# Set fd as the default source for fzf
export FZF_DEFAULT_COMMAND='fd -type f --follow --hidden --exclude .git'

# Apply the command to CTRL-T as well
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"

# Preview contents of files
export FZF_CTRL_T_OPTS="--preview '(highlight -O ansi -l {} 2> /dev/null || cat {} || tree -C {}) 2> /dev/null | head -200'"

# Set color scheme to Dracula
export FZF_DEFAULT_OPTS=$FZF_DEFAULT_OPTS'
--color=dark
--color=fg:-1,bg:-1,hl:#5fff87,fg+:-1,bg+:-1,hl+:#ffaf5f
--color=info:#af87ff,prompt:#5fff87,pointer:#ff87d7,marker:#ff87d7,spinner:#ff87d7
'

# Start the finder in a tmux split pane
export FZF_TMUX=1

Ctrl-r

Paste the selected command from history onto the command-line.

Pressing Ctrl-r again will show the commands in chronological order.

Alt-c

cd into the selected directory.

# Use fd here as well
export FZF_ALT_C_COMMAND="fd -t d"

# Preview files
export FZF_ALT_C_OPTS="--preview 'tree -C {} | head -200'"

Using the finder

  • Ctrl-k / Ctrl-j (or Ctrl-p / Ctrl-n): Move cursor up/down.
  • Enter: Select the item.
  • CTRL-C / CTRL-G / ESC: Exit.
  • On multi-select mode (-m), Tab and Shift-Tab: Mark multiple items.

fzf.vim

:Files # $FZF_DEFAULT_COMMAND
:GFiles # `git ls-files`
:GFiles? # `git status`
:Buffers # Open buffers

:Maps # Normal mode mappings
:Colors # Color schemes
:Rg # Search in files (ripgrep)

Key bindings

  • Ctrl-x: Open in a new split.
  • Ctrl-v: Open in a new vertical split.
