Indeed, agree, only I'm not sure if it's a bug or a feature :) because I think the original CLI autocomplete task was for CLI commands only - right, @kociolekscramjet ?
But I see would be useful to have files/dirs for pack. I'm not sure what is the time effort, maybe @kociolekscramjet can comment on it. He did a marvelous job on autocomplete but I remember it wasn't super easy to make it work.
One thing I would change in the future in CLI autocomplete script is moving it to a separate file and only including it in .bashrc., because it is making .bashrc messy. Plus, I think it installed the script twice when I accidentally ran the install command again:

Yes as you mentioned @alicja-gruzdz initial task mentioned autocompletion for command names only. But those are good suggestions! As the initial part is completed, and is working now, both changes - the filename completion and the failsafe cleaner way of injection into bashrc shouldn't be too time consuming.

The filename completion: I think it should be covered with modification in commands/completion.ts:25 where proper data is provided but we need to write the handler for the completion - a little research needed

The cleaner installation script: Changes should be done in here commands/completion.ts:47 for now it's just si completion bash script piped to users bashrc.
