What I am not sure is why this is printed on the title of the email. Where is what is printed on the email title controlled from? Is it editable? It's cron's default. If it sends a mail, by default it does this: The subject is the program field in the crontab The body is the output from the program. You can't normally change that. What you do is edit your called script to intelligently mail you the information you do want, and send all output to devnull to suppress cron's default mailer settings -- alan dot mckinnon at gmail dot com

[gentoo-user] Receiving mail from crontab
Hi All, I am getting a bit confused from the messages that I receive in my gmail account sent from my crontab. First, is related to the title which is: Cron r...@mylaptop test -x /usr/sbin/run-crons /usr/sbin/run-crons I am not sure what this test -x part represents? The second question is related to the output of chkrootkit, which is run by the cron.weekly and emails stuff that don't make much sense to me: == $Ld$ Ll$(Lt$0HÄ8ÃAWAVAUIýATUSHH°èHAÇHÝHL$ØMäITMt$(HÒtdfDIt$ Hötm½(Ht8fLïèHþÿÿITHÃHÆLïèHßèHîHÅ(It$ HuÊIMôIÆ(HÒu¢DÿèH1À[]A\A]A^A_ÃLæLïèþÿÿëÊLïH5H421ÒèoþÿÿDÿèëÃDS1öH°H;èHß[éCopyright (C) the VideoLAN VLC media player developersLicensed under the terms of the GNU General Public License, version 2 or later.Freebox TV listing (French ISP free.fr services)http/shout- winamp://www.shoutcast.com/sbin/newxml.phtmlhttp/shout- winamp://www.shoutcast.com/sbin/newtvlister.phtml?alltv=1http://mafreebox.freebox.fr/freeboxtv/playlist.m3uhttp://www.canalplus.fr/index.php?pid=1784shoutshoutcast- limitShoutcastShoutcast radio listingsservices_discoveryshoutcastShoutcastTVShoutcast TV listingsshoutcasttvfrenchtvFrench TVFreeboxfreeboxStarting FreeboxStarting FrenchTVStarting ShoutTVStarting ShoutRadiono-playlist- autostartItemAddedShoutcast RadioShoutcast TVFreebox TVvlc://nopCanal +Les Guignolshttp-forward-cookieszRL«ACF0lsJG ,A¤,A¼,AÔ)aìog0...@4dûbbb E(A0A8D@| GCC: (Gentoo 4.3.4 p1.0, pie-10.1.5) 4.3.4.symtab.strtab.shstrtab.rela.text.data.bss.rodata.str1.8.rodata.str1.1.rela.data.rel.ro.local.rela.eh_frame.comment.note.GNU- stack @1...@2s == Now I happened to notice that the above legible references to vlc are from the services discovery list that the vlc player shows under Media/Services.

I am not sure I understand why chkrootkit is emailing these to me and if I need to do something about it. cron captures the output from any program it runs. If there is any output at all, it will mail it to you. In this case, something launched by run-crons is spewing something to STDOUT and you are getting it in your inbox. As to what it means, well it looks like garbage. So you will have to run the chkrootkit program yourself and debug how it is going wrong and fix it. This, of course, has nothing whatsoever to do with cron itself. The output looks like standard banner garbage that apps often write to the terminal when launched.
