Ubuntu – No tab completion with asterisk *

auto-completionbash

I am not able to tab complete from the command line in gnome-terminal when I have an asterisk in the command line. Default shell is bash, using gnome-terminal. For example,

This works to copy a single file into a dir using tab-completion on the ~/files/ directory:

cp ~/file1 ~/files/

However this does not work using tab completion on the directory when I want to copy multiple files into a dir (I have to manually type out or paste ~/files/):

cp ~/file* ~/files/

(Assuming there exist the files file1, file2, file3 & file4)

And this does tab complete the directory (and works as I would expect regex to work, copying all of those files into ~/files/):

cp ~/file?* ~/files/

So I do have a workaround. But I know I have had this working before without having to use the ? and I'm not exactly sure how or when I lost it. As a heavy command line user I've been living with it, but it's been relatively annoying lately.

END EDIT1-


I have not changed my /etc/inputrc or added an ~/.inputrc.

The package bash-completion is installed.

I have uncommented in my .bashrc the section that enables tab-completion quite a long time ago (it works well in all other instances and this problem I now have WAS working before).

It does not work in any of the terminals I have installed in my system (Ubuntu 14.04). And in case someone is thinking this, no it's not a valid solution to re-install Ubuntu. 🙂

Best Answer

The solution was to comment out a function I had added to my ~/.bashrc. The function was used to do some funky tab-completion regarding alias's. (Found it on the interwebs, I won't get into it here)

I used justsomeguy's suggestion to do env -i bash --noprofile --norc. And completions worked normally.

I then did env -i bash --norc -- completions still normal.

Then did env -i bash and the completions were failing again. So I concluded that the problem was in my ~/.bashrc and troubleshot from there.

Thanks for the help!
