This is how you reorder every pair of two lines, thus going  from
1,2,3,4,... to 2,1,4,3,...:  [0]

     sed -n 'h;n;G;p'

Here Perl impressed me much:  [1]

     perl -pe '$_=<>.$_'

How elegant!


Btw: This is valid sed:
     sed 'super sed fun for you'

Maybe we should start writing poems in sed as well, not  only  in
Perl.
