Quick question about the command find.

 I definitely want to erase  backups that are older than 15 days using cron.   Maybe I made a typo when  trying rm -rf in  ny test folder.

Thanks for your help

Without -r rm won't erase any directory, empty or not. rmdir will delete
directories iff they are empty.

And these errors were exactly...?

By default, find ANDs multiple tests. Therfore,
find $MyPath -type d -mtime +15
should print all directories below $MyPath which were not modified for
more than 15 days.

want to recursively delete those directories regardless whether or not
they contain files or directories with a more recent mtime. If not, rm
-r is obviously not what you want to use.
