I am not bash expert. I need to write a script to copy latest (by date) file from one folder to another as following

from

/test/a/date1.bak
/test/a/date2.bak
/test/a/date3.bak 
/test/b/date1.bak
/test/b/date2.bak
/test/b/date3.bak

to 

/test/a/sec/date1.bak
/test/b/sec/date1.bak

On the second step I need to delete oldest file by date in the destination directory

from

/test/a/sec/date1.bak
/test/a/sec/date2.bak
/test/b/sec/date1.bak
/test/b/sec/date2.bak

to 

/test/a/sec/date1.bak
/test/b/sec/date1.bak
