!! will execute the last command
!-1 will execute the 2nd command from last

Few other tricks:
-----------------

If you are not sure you can see what is the command rather than executing by

!!:p
!-2:p

and later just do !!

If you want to run the last command with little modification use substitution

!!:s/old/new

example:

>vim test
>!!:s/test/abcd/:p
vim abcd
