The family's favorite fuzzy finder.
|
|
Basically, it takes a list then create an interface out of it.
|
|
Not only it is easy to use and very flexible but also very configurable with the options to let you choose the keybindings and the previewer among other things.
|
|
|
|
|
|
|
|
|
|
* Options
|
|
|
|
- =-m, --multi= - enables multiple selection; by default, the keybinding to select is =Tab=
|
|
- =-p, --prompt= - display the prompt message
|
|
- =--disabled= - disable the search making fzf essentially a selection interface
|
|
- =--cycle= - enables cyclic scrolling in the selection (it's annoying when it does not have those)
|
|
|
|
If no input was passed, it will recursively list all of the files in the current directory.
|
|
Pretty useful for a quick opening interface.

* Examples

|
|
|
My favorite section where I get to show off some scripts featuring the star of the show.
|
|
And also this is where everyone is going to go first.
|
|
|
|
|
|
** Basic command-line file selection
|
|
|
|
#+begin_src bash
|
|
fzf | xargs xdg-open
|
|
#+end_src
|
|
|
|
|
|
** Quick manual page selection
|
|
|
|
#+begin_src shell
|
|
apropos . \
|
|
| fzf --multi --prompt "Choose manual(s) to open > " \
|
|
| awk '{ print $1 "." gensub(/[()]/, "", "g", $2) }' \
|
|
| xargs man
|
|
#+end_src
|
|
|
|
|
|
** Goto directory with fzf and Bash
|
|
|
|
With my favorite =find= replacement, [[https://github.com/sharkdp/fd][=fd=]].
|
|
It's a Bash function since [[https://stackoverflow.com/a/255415][you can't propagate directory changes with a script]].
|
|
Just have to put it somewhere in your configuration.
|
|
|
|
#+begin_src bash
|
|
function fzf-cd() {
|
|
local dir=${1:-$(pwd)}
|
|
local dest=$(fd --type directory --hidden --base-directory "$dir" --follow | fzf --prompt "Where to go? > ")
|
|
[[ $dest ]] && cd "$(realpath --logical "$dir")/$dest"
|
|
}
|
|
#+end_src
|
|
|
|
Even better when you bind it with a keybinding (e.g., ~bind '"\C-f":'fzf-cd\n"'~).
