title: FZF
---
[fzf](https://github.com/junegunn/fzf)
is a fuzzy selection tool written in [[go]]. An alternative in [[rust]] would be
[skim](https://github.com/lotabout/skim).
[[fzf]] can be used to automate a lot of things, for example it can replace the
`CTRL-R` shortcut in bash:
```bash
## Include in your .bashrc:
source PATH_TO_FZF_CLONE/shell/key-bindings.bash
```
And now, `CTRL-R` will fuzzy search the history.
`fzf` is a huge productivity boost for commandline work and even other tools
where it integrates.
Some more examples:
```bash
## fco - fuzzy checkout git branch
fco() {
local tags branches target
local fzf_cmd="fzf"
tags=$(git tag | awk '{print "\x1b[31;1mtag\x1b[m\t" $1}') \
|| return
branches=$(git branch --all | grep -v HEAD | \
sed "s/.* //" | sed "s#remotes/[^/]*/##" | \
sort -u | awk '{print "\x1b[34;1mbranch\x1b[m\t" $1}') \
|| return
[[ $TMUX ]] && [[ $(which fzf-tmux 2>/dev/null) ]] && \
fzf_cmd="fzf-tmux -l30 -- "
target=$( (echo "$tags"; echo "$branches") | \
$fzf_cmd --no-hscroll --ansi +m -d "\t" -n 2) \
|| return
git checkout $(echo "$target" | awk '{print $2}')
}
## Fuzzy foreground, if you use `CTRL-Z` a lot
fj() {
[ $(jobs | wc -l) -eq 0 ] && return
local j=$(jobs | awk '{ print $3, " - ", $2, " - ", $1; }' | fzf -1 -0)
echo $j
fg $(echo $j | sed -r 's/(.*)\[([0-9]*).*/\2/g')
}
## Fuzzy select the right tmux session, even within a tmux session
fmux() {
local session
session=$(tmux list-sessions -F "#{session_name}" | \
fzf --query="$1" --select-1 --exit-0)
if [[ -z "${TMUX}" ]]; then
tmux -2 attach -t "$session"
else
tmux -2 switch-client -t "$session"
fi
}
```
## fzf in vim
It can also be integrated in `vim` for fuzzy selecting. Things like
fuzzy-jump-to-line, for example:
```viml
" Using the fzf-preview plugin, this can even be enhanced with a preview window:
nmap <Leader>zf :FZF<CR>
nmap <Leader>zr :FZFRg<CR>
nmap <Leader>zh :FZFHistory<CR>
nmap <Leader>zl :FZFBLines<CR>
nmap <Leader>zt :FZFTags<CR>
nmap <Leader>zT :FZFBTags<CR>
nmap <Leader>zm :FZFMarks<CR>
nmap <Leader>zw :FZFWindows<CR>
```
