Stupid of me to miss that. Most sed implementations want backslashes on the parentheses.

Code:
sed -e 's/\([0-9][0-9]\)-\([A-Za-z]+\)-\([0-9][0-9][0-9][0-9]\)/\3\2\1/' file

And if they're really stupid they don't even understand the +

Code:
sed -e 's/\([0-9][0-9]\)-\([A-Za-z][A-Za-z]*\)-\([0-9][0-9][0-9][0-9]\)/\3\2\1/' file

But that just rearranges the order of the fields, it doesn't magically convert month names to numbers. There was another thread on that recently.

The printf format error would seem to indicate you do not have ksh93 version h or better, is that correct? Read what fpmurphy wrote.

The general problem of a myriad different date formats is still not really tackled. I don't know if it could be -- how do you know if 03/12 is December 3rd or March 12th? (In computer-generated dates, dashes are usually an indication of European, aka sane order, whereas slashes tend to be used in American dates; but it depends on the application which generated these. Or are they human-generated? And of course, if they are written by Americans, you can make certain assumptions.)
