UNIX move file name with sysdate

Question

I want to make a script in Unix in which I have to move a file daily to a specific path. In order to avoid overlapping of the file, I want the file name along with the date.

e.g. mv filename /home/bin.
How can I add the date to the file name?

Answer 1

mv "filename.ext" "/home/bin/filename-$(date +%Y%m%d).ext"

Answer 2

mv filename.ext{,.$(date +%Y%m%d)}
