It would be more efficient (and it seems from the conversation on
this note that some don't know all the features of history) that
instead of using tail, to say how many history lines you want.  For
example:
         history | tail -1

is the same as:

         history 1

To save typing, try:

alias history 'h'
h 1

Similarly, instead of

         history | sed ... | tail -\!*

use
         history \!* | sed ...

(It will also execute slightly faster).
