Shell script to remove oldest file

Hi,
I have two set of files in a directory called /tmp/backup. I want to write a script to remove the oldest of these two, so that there is space available for a newer similar backup file.

For example,
I have
/tmp/backup/dbbackup_dbname_121223112 (oldest)
/tmp/backup/dbbackup_dbname_321445563 (latest)

Now I want my script to remove the oldest
/tmp/backup/dbbackup_dbname_121223112

and if the same script is run next day it should remove
/tmp/backup/dbbackup_dbname_321445563

I am thinking about a command in script such as below

Code:
find rm -f `/tmp/backup/dbbackup_dbname -mtime +2`

(not sure about this, please advice)

Thanks.
