while ( "$1" != "" )
set ext=`expr "$1" : ".*\(\..*\)"`
set newname=$prefix`stat -f "%Sm" -t "%F_%H:%M:%S"`
echo moving $1 to $newname$ext
mv $1 $newname$.ext
I'm not sure "stat" works in 4.x
If two [or more] files are created at exactly the same time,
the one with the last name --in lexicographic order--
will overwrite the others.
Hope it helps.
