I don't have a Linux box at work, but I think this is what you are after:

sed -e '/^$/d' filename > newfilename

or

sed -n -e '/^..*$/p' filename > newfilename

Or this might work, but it seems less likely...

sed -e 's/^$//' filename > newfilename

The /g is not required with sed, since sed applies commands to every
line anyway.

In vim, prefix your command with a line range:

:a,b/^$/d

where a,b are the start and end line numbers respectively.  You can
use 1,$ for the whole file.

(Grant's e-mail gives an even more efficient solution in this case).
