Like a shell script

I have come up with this:

#!/bin/sh



# unless you remove this line, this script runs dry

echo=echo



for newfid in /drive?/fids/_*/*

do

        # try not to use external commands for speed

        oldfid=${newfid#drive?/fids/_}

        oldfid=${oldfid#0}

        oldfid=${oldfid#0}

        oldfid=${oldfid#0}

        oldfid=${oldfid#0}

        oldfid=${oldfid#0}

        oldfidhi=${oldfid%/*}

        oldfidlo=${oldfid#${oldfidhi}/}

        oldfid=${newfid%%/*}/fids/${oldfidhi}${oldfidlo}



        if test $newfid -nt $oldfid

        then

                # move the new-scheme fid if it is newer

                $echo mv -v $newfid $oldfid

        else

                # delete it otherwise

                $echo rm -vf $newfid

        fi

done

However, it does not take care of the effect that mp3tofid uses a different
algorithm to distribute fids across drives than (j)emplode/player. It should
work if you only have one drive, though.

Onother gotcha is that file date comparisons may not work if your player's
idea of the date is off. mp3tofid/rsync stores the file dates of the source
files, while the player uses the current date of the player.
