Delete files 30 days old

Will this work to delete files 30 days old in $backupDir or is there a better way to do it?

find $backupDir -type f -mtime +30 -exec rm {} \;

If you have a lot of old files to remove, this may be noticeably faster:

find $backupDir -type f -mtime +30 -exec rm {} +

When you terminate the -exec primary with a semicolon, you invoke rm once for each pathname to be removed; with a plus sign, rm will be passed a group of pathnames to remove.
