I don't know why you want an alias for this, but let's
look at what it does:

That means whenever you type 'xtra' the following 
sequence of commands will be executed:

(1) dd if=/dev/zero bs=1024k count=8 of=/swap

All that does is put zeros (8192k of them) into a file 
called swap (in the / directory)

(2) mkswap /swap 8192

That formats the file as a swap file (8mb).

(3) sync

That makes sure the file is fully updated.

(4) swapon /swap

That activates swap (using that file).

When you execute 'free', what are the values for
swap total, swap used and swap free?  What do you
get when you execute 'dir /swap'?
