Problem / Steps to reproduce

I'm using a pretty normal ubuntu version

❯ lsb_release -a
No LSB modules are available.
Distributor ID:	Ubuntu
Description:	Ubuntu 20.04.2 LTS
Release:	20.04
Codename:	focal
❯ uname -a
Linux logos 5.4.0-77-generic #86-Ubuntu SMP Thu Jun 17 02:35:03 UTC 2021 x86_64 x86_64 x86_64 GNU/Linux

and bash as shell

❯ echo $SHELL
/bin/bash

Installed FZF via
sudo apt-get install fzf

❯ fzf --version
0.20.0

I have no experience in using fzf and checked the normal stuff. FZF is working fine by command. Really great and I like it.
I did add to the bashrc

export FZF_DEFAULT_COMMAND='rg --files --hidden --follow --no-ignore-vcs'
export FZF_CTRL_T_COMMAND="$FZF_DEFAULT_COMMAND"
export FZF_DEFAULT_OPTS='--height 40% --layout=reverse --border --preview "cat {}"'

But the autocompletion doesn't word like
cd **[tab] -> nothing happens
and the Key bindings (CTRL-T, CTRL-R, and ALT-C) neither.

So I checked out these threads, but couldn't find a solution to get it working.
#872
#227

In these threads are mentioned:

❯ complete | grep cd$
complete -o nospace -F _cd cd

And

❯ complete -o nospace -o plusdirs -F _fzf_dir_completion cd

~ 

got the following result
❯ cd **bash: completion: Funktion _fzf_dir_completion' nicht gefunden. (Funktion_fzf_dir_completion' nicht gefunden. -> Function `_fzf_dir_completion' not found.)

I was a little confused and thought that something else was interacting with FZF. But I got the same results, when I'm doing the same on my laptop (same Ubuntu, same installation of FZF; no bashrc edited) instead of my desktop.

Maybe its up to me and I can't figure it out, how to get it work. But normally it should work by default, I guess. Someone else here with the same/similar problem?

PS.: Maybe this issue (#2480) is related too (but different ubuntu -> 21.04)

My bad. I didn't read this page to the point where ...
https://github.com/junegunn/fzf#using-linux-package-managers

Key bindings (CTRL-T / CTRL-R / ALT-C) and fuzzy auto-completion may not be enabled by default.

Refer to the package documentation for more information. (e.g. apt-cache show fzf)

Doing so, it says:

❯ apt-cache show fzf
...to long didnt read...
...
 Refer /usr/share/doc/fzf/README.Debian for quick instructions on how to
 add keybindings for Bash, Zsh, Fish to call fzf.

Going there /usr/share/doc/fzf/README.Debian:

Bash
====

Append this line to ~/.bashrc to enable fzf keybindings for Bash:

   source /usr/share/doc/fzf/examples/key-bindings.bash

Append this line to ~/.bashrc to enable fuzzy auto-completion for Bash:

   source /usr/share/doc/fzf/examples/completion.bash

Adding these lines to the bashrc did solve the problem. Everything is working fine and how it should work (ALT C, cd **, etc.pp.).

For Fedora the solution is the similar /usr/share/doc/fzf/README.Fedora but subtly different:

To enable shell key bindings, source the applicable script from
/usr/share/fzf/shell from your shell initialization. For example, use
/usr/share/fzf/shell/key-bindings.bash in ~/.bashrc for user-wide bash.

The addition of the auto-completion and actual code you can copy and paste in the README.Debian file is really helpful. So this description works for Fedora:

Append this line to ~/.bashrc to enable fzf keybindings for Bash:

   source /usr/share/fzf/shell/key-bindings.bash

There doesn't appear to be any auto-completion for Fedora bash.

Also the Fedora dnf -C info fzf command misses the handy Refer to /usr/share/doc/fzf/README.Fedora ... in its output.

For me, it also doesn't work but I did the above steps (Ubuntu/Debian here):

• I have read through the manual page (man fzf)
• I have the latest version of fzf
• I have searched through the existing issues

Problem / Steps to reproduce

For gnome-terminal the completion and keybindings did not work after the installation. And now when using source /usr/share/doc/fzf/examples/completion.bash as it's written in the README.Debian in the command line, it works (cd **<tab>). But when adding the same line in .bashrc or using

if [ -f /usr/share/doc/fzf/examples/completion.bash ]; then
    . /usr/share/doc/fzf/examples/completion.bash
fi

in the same way .bash_aliases is integrated, it doesn't work.

In short, how can I add the source ... in the .bashrc to get it work without using source ... before every session?

Thank you very much for your help!

Solved with a hint of the irc-channel #bash by putting the implementation at the end of .bashrc and now it works perfectly.

Everything for me working great but i have a question
How i can make auto complete working without (Ctrl+R)?
For example if i write

sudo

It's should give me a auto complete with mute color to that command (if was last one that i used)

sudo apt update
