cron.daily, howto control mailed reports
Hi people. In a server I setup recently I tougth of keeping the clock sinc'ed by running ntpdate daily. I wrote a script calling /etc/init.d/ntpdate restart and I placed it in /etc/cron.daily. Why do I receive daily reports (in my mail system) from this particular script being runned, but not from other also existant in /etc/cron.daily? Ps: I just notisted an report from another script that I'm running hourly.. but it seems to have only reported 1 time, when there was an output to stdout... can that be it? If there is something in stdout cron will report to the mail system, otherwise it will run silently? Thanks Joao Clemente -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.

set the MAILTO variable in the script eg #!/bin/bash MAILTO=[EMAIL PROTECTED] /etc/init.d/ntpdate restart afaik, that would work. Joao Clemente wrote: Hi people.

If you want it to run silently, you can put MAILTO= in /etc/crontab But otherwise cron jobs only mail if there's output to stdout, so if you want more out put, not less, you'd have to set each one individually (I think). -- -Benjamin Matthew A'Lee, currently trying to make sure Mutt doesn't let him accidentally reply to sender instead of reply to list...

Thanks Benjamin, running silently was what I was looking for. Robert: no problem, thanks for the answer anyway :-) Joao Clemente -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe. Trouble? Contact [EMAIL PROTECTED]

If any cron script outputs anything on stdout or stderr, the output is emailed to you (according to MAILTO). The standard cron scripts don't output anything unless something goes wrong (e.g. you type killall updatedb while it's running). Your ntp script will output stuff even when it goes right, hence the message. You should do something like: ntpdate -s pool.ntp.org the -s puts the messages in syslog instead of stdout, to quote the manpage, primarily for convenience of cron scripts (speaking of which, my ntpdate script obviously isn't working, my clock was wrong again!) -- To UNSUBSCRIBE, email to [EMAIL PROTECTED] with a subject of unsubscribe.
