You need to use the substitute command, match and mark stuff on the left with ( ) and recall it on the right with \1 \2 \3, etc. In this case sed -n 's/([0-9][0-9])-([0-9][0-9])-([0-9][0-9][0-9][0-9])/\3-\1-\2/' <inputfile. Untested.

Oops -- this editor lost the backslashes in front of ALL the left and right parentheses in the above. Kindly insert them while I figure out how to deal with this editor!
