automatic tab completion does not work

[abhijit]

Tab completion is not working with most of the commands.

It works with "cd" and not with any another commands.

When I type "mkdir /t" and then press tab it completes into "mkdir /tmp " . Note the space at the end. It should complete to "mkdir /tmp/".

Similarly for files with a space in the name, it does not automatically add the "\ " but just adds the " " space character. So the commands do not work.

I have attached the output of dpkg -l, because i suspect it is broken due to some package.
