find newer files

Anindya Ganguly posed the following problem "After simulations, how
to move modified files to a different folder?"


$ touch {1..3}.txt     #create files
$ sl; sl	       #procrastinate

$ touch {a..c}.txt     #create new files

Now identify the latest file. It can be done automatically
but also by hand. Say this file is "3.txt"

$ find * -newer 3.txt     #list all files "newer" than 3.txt
a.txt
b.txt
c.txt

Now we wish to move this to another directory.
So let us first create this directory

$ mkdir ../newfiles

$ mv $(find * -newer 3.txt) ../newfiles
