Tab completion doesn't work for commands
The installed packages prompt is working fine, eg,
gedtab completes to
gedit, but package autocomplete on apt-get is not showing list of matching packages, like,
sudo apt-get install gedtab won't try to fit
ged* packages as it normally should. Similarly,
quicklytab pops files and folders in the current directory instead of prompting "commands , create, etc".
Any way of correcting this? And yes, I'm on Ubuntu 12.04.
