I want completion like in emacs that if there is only a sole completion to the command you are typing, than you don't need to type it all.

For example:

package ins

is enough instead of typing the whole:

package install

Is there a package or script that does that?

I am looking for a solution that doesn't require hitting the tab key but rather hitting the enter straight away and having a script do the auto completion before running the command.


I believe fish shell would be in order here. To install:

  1. Download from here

  2. Then use this tutorial to assist you learning.


bash does that by default if the bash-completion package is installed, just type e.g.

> apt i

press Tab ↹ and you'll get

> apt install

If there are multiple matches, pressing Tab ↹ another time will display a list of them., e.g.

> ap

Tab ↹

nothing happens

Tab ↹

apparmor_status               appres                        apt-config                    aptitude                      apt-sortpkgs

  • Thank you for you fast response, I am aware of this but am looking for auto completion without the need of pressing the tab key.

  • I am looking for a solution in which I for instance can type "package ins" and hit enter rather than hitting the tab key. I know it only takes a second to hit the tab key but I am curious if such solution exists.

If your problem is you want Bash Completion, please refer to the post Terminal autocomplete doesn't work properly, else if you need Enter become as like Tab ↹ and also execute that command immediately, then you need to add the command below in your ~/.bashrc and then source ~/.bashrc it.

bind 'RET:"\C-i\C-j"'

The RET is shortened for RETURN; You could use "\C-M" instead as well which is stands for Ctrl+M.


You need to install bash-completion. If already installed, you need to source it:

source /etc/bash_completion

You can add it in your .bashrc file. You can add custom completions in /etc/bash_completion.d/
