Shell Programming and Scripting

1. If I want to check directory INPUT which files are not update within
5 minutes then move them to DATA1 directory
$ echo a > A.20060321.txt;echo b > B.20060321.txt;echo c > C.20060321.txt;
echo d > D.20060321.txt
$touch control_time; sleep 300
$find . ! -newer control_time -name "*.txt" -print

How do I make a script so if it is not update in 5 min then move it to
directory DATA1 ?

2. If in DATA1 directory have 4 files A, B, C, D with the same date like 20060321
then move it to DATA3 directory ,


3. And if that date like 20060321 have 4 files then
also move all of the files before that date to DATA4.
Thanks.

Here is my code for this
find . ! -newer control_time -name "*.txt" -exec mv {} ./DATA1 \;


Anyone know about 2 and 3 ? Thannks !
