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. :)

  • Please edit your post to include the output of compopt cp. Also, try set -x, then do cp file* ~/file<tab>. The output might be informative.

    Have you tried creating another user account to see if it also has the same problem?

    Perhaps you should test gobbing out in a shell that doesn't load your profile or rc files. Eg: env -i bash --noprofile --norc. If everything works after that, then you can use process of elimination to determine what lines of your bash configuration files are to blame. Otherwise, you have something weird going on.

    Do you still have this issue?

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!
