Common Use Cases
Use Case: Git Branch Checkout
# Interactive git branch selection
git checkout $(git branch -a | fzf | sed 's/^[ *]*//' | sed 's/remotes\/origin\///')
# Or create an alias
alias gcb='git checkout $(git branch | fzf | sed "s/^[ *]*//")'
Use Case: Kill Process
# Find and kill process interactively
kill -9 $(ps aux | fzf | awk '{print $2}')
# Or create a function
fkill() {
local pid
pid=$(ps aux | sed 1d | fzf -m | awk '{print $2}')
if [ "x$pid" != "x" ]; then
echo $pid | xargs kill -${1:-9}
fi
}
Use Case: SSH Host Selection
# Select from SSH config hosts
ssh $(grep "^Host" ~/.ssh/config | grep -v "[?*]" | cut -d " " -f2- | fzf)
# Or create an alias
alias fssh='ssh $(grep "^Host" ~/.ssh/config | grep -v "[?*]" | cut -d " " -f2- | fzf)'
Use Case: Directory Navigation with History
# Create a function to track and jump to directories
fcd() {
local dir
dir=$(find ${1:-.} -path '*/\.*' -prune -o -type d -print 2> /dev/null | fzf +m) && cd "$dir"
}
# Jump to frequently used directories (requires z or autojump)
fz() {
local dir
dir=$(z -l 2>&1 | fzf --height 40% --nth 2.. --reverse --inline-info +s --tac --query "${*}" | sed 's/^[0-9,.]* *//')
cd "$dir"
}
Use Case: Docker Container Management
# Select and attach to running container
docker exec -it $(docker ps | fzf | awk '{print $1}') /bin/bash
# Select and stop containers
docker stop $(docker ps -a | fzf -m | awk '{print $1}')
# Select and remove images
docker rmi $(docker images | fzf -m | awk '{print $3}')
Use Case: Environment Variable Viewer
# Browse and copy environment variables
env | fzf --preview 'echo {}' --preview-window=up:3:wrap \
--bind 'enter:execute(echo {} | cut -d= -f2 | pbcopy)+abort'
Use Case: Log File Analysis
# Search through log files with preview
find /var/log -type f 2>/dev/null | fzf \
--preview 'tail -100 {}' \
--bind 'enter:execute(less {})'
# Search log content
grep -r "ERROR" /var/log 2>/dev/null | fzf \
--delimiter=: \
--preview 'bat --color=always {1} --highlight-line {2}' \
--preview-window +{2}-/2
Best Practices
-
Use with fd or ripgrep: Replace
findwithfdfor faster file searching:export FZF_DEFAULT_COMMAND='fd --type f' -
Enable preview by default: Add preview windows to see file contents before selection, improving accuracy and reducing mistakes
-
Create shell aliases: Build custom aliases for frequent workflows (git operations, SSH connections, process management) to maximize productivity
-
Combine with other tools: Integrate fzf with
batfor syntax highlighting,treefor directory previews, anddeltafor git diffs -
Use multi-select wisely: Enable
--multimode when you need to operate on multiple items (deleting files, checking out multiple git files) -
Leverage key bindings: Customize
--bindoptions to create shortcuts for common actions (open in editor, copy to clipboard, execute commands) -
Optimize for large datasets: Use
--algo=v2and consider--syncmode for very large file lists to improve performance -
Set appropriate heights: Use
--height 40%or similar to avoid full-screen takeover, maintaining context of your current work -
Configure color schemes: Match fzf colors to your terminal theme for better visual integration and reduced eye strain
-
Use field delimiters: When parsing structured output (like
psordocker), use--delimiterand--nthto search specific columns
Troubleshooting
| Issue | Solution |
|---|---|
| Key bindings not working | Run the install script: ~/.fzf/install or source the shell integration file in your RC file |
| Slow performance with large file lists | Use fd or ripgrep instead of find: export FZF_DEFAULT_COMMAND='fd --type f' and consider --algo=v2 |
| Preview not showing file contents | Ensure preview command is correct and file is readable. Try --preview 'cat {}' or install bat for better previews |
| Colors not displaying correctly | Check terminal supports 256 colors. Use --color=16 for basic color support or adjust color scheme |
| Command not found after installation | Add fzf to PATH or restart shell. For Homebrew: ensure /usr/local/bin or /opt/homebrew/bin is in PATH |
| Unicode characters not rendering | Ensure terminal and locale support UTF-8: export LC_ALL=en_US.UTF-8 and use a Unicode-capable font |
| fzf consuming too much memory | Reduce input size or use --sync mode. Consider filtering input before piping to fzf |
| Preview window not updating | Use --preview-window=follow for auto-scrolling or toggle preview with Ctrl+/ to refresh |
| Cannot select items with mouse | Mouse support may be disabled. Remove --no-mouse option or click outside fzf and retry |
Completion not working with **<Tab> | Ensure shell integration is loaded. Check ~/.fzf.bash or ~/.fzf.zsh is sourced in your RC file |
Search Syntax
| Syntax | Description | Example |
|---|---|---|
term | Fuzzy match | fzf with input “abc” matches “a_b_c.txt” |
'term | Exact match (single quote prefix) | 'abc matches only “abc” exactly |
^term | Prefix exact match | ^abc matches “abc…” but not “zabc” |
term$ | Suffix exact match | abc$ matches “…abc” but not “abcz” |
!term | Inverse match (exclude) | !test excludes lines with “test” |
term1 term2 | AND match (both required) | foo bar matches lines with both terms |
| `term1 \ | term2` | OR match (either required) |
Useful Shell Functions
# Open file in editor with preview
fe() {
local files
files=$(fzf --query="$1" --multi --select-1 --exit-0 \
--preview 'bat --color=always --line-range :500 {}')
[[ -n "$files" ]] && ${EDITOR:-vim} "${files[@]}"
}
# Change to directory with preview
fcd() {
local dir
dir=$(fd --type d --hidden --follow --exclude .git | fzf \
--preview 'tree -C {} | head -100') && cd "$dir"
}
# Git commit browser
fgc() {
git log --oneline --color=always | fzf --ansi \
--preview 'git show --color=always {1}' \
--bind 'enter:execute(git show {1} | less -R)'
}
# Browse and install packages (Debian/Ubuntu)
fap() {
apt-cache search . | fzf --multi --preview 'apt-cache show {1}' | \
awk '{print $1}' | xargs -ro sudo apt install
}
