It's not really clear what you intend to do exactly. But here is a couple
of pointer:

1) If you don't use -n 1 then you will read a whole line. So you will need
to type exactly one tab and press enter.
2) since you use -i "$cmd" you need to make sure you delete whatever is put
by default
3) since you use -e, pressing tab will not insert a "TAB" character,
instead it will try to complete, to be able to input a tab
you will need to press "control-v" then a TAB

Having said that, are you trying to implement completion?
