I have a script for auto-completing my ssh-hosts. If I change my ~/.ssh/config the auto-completion is not updated automatically, though. This does not surprise me. In a new shell, the new entry is picked up and usable, of course.

How do I manually trigger a refresh of the completion in bash?

Try doing this :

exec bash

this will do the trick...

    neat, that replaces the current shell... In a way, that like opening a new shell, but still nice.

See reload bash completion functions file

. /etc/bash_completion.d/filename

(adapt /etc depending on where your bash_completion scripts are deployed, replace filename by the appropriate script)

    Usually . /etc/bash_completion is my solution. Mar 2, 2018 at 11:03

    @JoelBerger I could hazard a guess... the files mentioned here are themselves bash scripts, so by running them in this way, you're resetting the bash settings just as you would running any bash script. Running /etc/bash_completion is likely best if available, as it reruns all the completion scripts. Jun 16, 2021 at 10:18
