Why are you using $_ instead of <ESC>_ ?

<ESC>_ will expand the last word in the previous command line and
you'll see it expanded before you hit return. This works in vi editing
mode.
It can be preceeded with a number n to use the n-th word from the BEGINNING
of the last command instead of the last word.

If you have the ksh book, look at the top of page 116.
