Kyle Evans 5b80de237b cron: add log suppression and mail suppression for successful runs ... This commit adds two new extensions to crontab, ported from OpenBSD: - -n: suppress mail on succesful run - -q: suppress logging of command execution The -q option appears decades old, but -n is relatively new. The original proposal by Job Snijder can be found here [1], and gives very convincing reasons for inclusion in base. This patch is a nearly identical port of OpenBSD cron for -q and -n features. It is written to follow existing conventions and style of the existing codebase. Example usage: # should only send email, but won't show up in log * * * * * -q date # should not send email * * * * * -n date # should not send email or log * * * * * -n -q date # should send email because of ping failure * * * * * -n -q ping -c 1 5.5.5.5 [1]: https://marc.info/?l=openbsd-tech&m=152874866117948&w=2 PR: 237538 Submitted by: Naveen Nathan <freebsd_t.lastninja.net> Reviewed by: bcr (manpages) MFC after: 1 week Differential Revision: https://reviews.freebsd.org/D20046		2019-09-25 02:37:40 +00:00
