Hi thre,
ls -Rlat > /home/csuser/myfile

Mean of the following switches are :---

-R includes the contents of subdirectories.
-l Shows you huge amounts of information (permissions, owners, size, and when last modified.)
-a Shows you all files, even files that are hidden (these files begin with a dot.)
-t Shows you the files in modification time.

And now output of this command will print to a file named "myfile" at location /home/csuser
