<syntaxhighlight inline>fzf</syntaxhighlight> is a fuzzy-finder on the terminal. I use it for all sorts of stuff.

Selecting a git branch:

<syntaxhighlight lang=zsh>
gco() {
  branch="$(git branch | grep -v '^\+' | fzf | tr -d '[:space:]' | sed 's/^\*//')"
  if [[ -z "$branch" ]]; then
    echo "No branch selected"
    return 1
  fi
	git checkout "$branch"
}
</syntaxhighlight>

You can also select multiple rows if you like

<syntaxhighlight lang=zsh>
gbd() {
  branches=$(git branch | fzf --multi | sed 's/^\*//' | sed 's/\s*//')
  git branch -D ${branches}
}
</syntaxhighlight>

And if you want a preview, you can get one too:

<syntaxhighlight lang=bash>
ls | fzf --preview 'ls -l {} | wc -l'
</syntaxhighlight>

I admit I do use it with <syntaxhighlight inline>kubectl config use-context</syntaxhighlight> but side-effects will occur.
