Re: [PLUG] Shell syntax vs crontab syntax

[Walt Mankowski via plug <plug@lists.phillylinux.org>]

Since the data comes to me as emails, it seems a lot easier to just
dump them into a maildir than come up with sort of database
solution. Also I'm not seeing how maildirs -- individual files I can
easily search with mutt -- is NOT a decent solution for dealing with a
large amount of data.

Honestly I mostly just scan the subjects to make sure things aren't
broken. I should probably just delete the older ones, but I've got
plenty of disk space. And again, this is much simpler in mutt (or even
just using rm) than it would be doing it in a database.
