7 day retention of archive files in unix

Question

I was supposed to remove the archive files that are at least 7days older or the files will be retain to the directory for about 7 days only. How can I execute it using shell script?

Thanks.

Answer 1

Using find

find /path/to/dir -mtime +7 -type f -exec rm {} \;

Answer 2

I think everyday (use cron) you'll check which files are older than 7 days
