Remove Files older than 3 years

I need to remove any file in the directory that is older than 2 years old. It is very important that I keep the newest files and delete the old files.

I have searched and found this.

find /path/to/files* -mtime +365 -exec rm {} \;


Can I just multiply the number?

find /path/to/files* -mtime +1095 -exec rm {} \;


Is there a way to add a switch that will print the file name to the screen as it removes it? To make sure it is doing what I am expecting?

I have also found this:

find /rec -mtime +365 -print0 | xargs -0 rm -f


Is there a major difference between the two? Is one better than the other? What I have read says that xargs is faster. Would I be able to multiply the mtime number out to a 2nd or 3rd year?

And finally would would I be able to place the code as it is into a cron job that can run daily?

Thank you!

Yes. And to "echo" before you remove

find /path/to/files -mtime +1095 -print

Then the version with -exec rm {} \; to remove the files (when you are ready).
