Automatic email sending with sendmail?

Stingreen · 04-11-2002, 07:16 PM

I want sendmail to send me the weekly logs every sunday at 1 o' clock. Is there any way to do this?
Well, if there is a command for this, I can setup the cronjobs to schedule weekly, but the problem is I don't know if there is a command for this or not..
Thank you,

You can setup a cronjob to execute the following command:

sendmail email@address.com < filename

That will cat the file into an email which will end up in the designated email box. There are a bunch of flags you can use too in order to specify a subject or get verbose output to capture in a log file separate from cron messages.

You can test it out from the command line first and tweak it as you need.

Hope that helps.

Thanks..
Can I expand my question a little bit?

Well, now, there is a script called "stats"
What I wanna do is, I want crontab to execute the stats like this,
# stats /var/log/maillog
and have the output mailed to myself.
Can I do this also?
thank you much.

Not knowing exactly how your stats script works, I'll take a stab....

If the stats script is generating a file (i.e. /var/log/maillog), then you can do a couple of things (off the top of my head):

1. Make the last step of the stats script be to execute the sendmail command with the < filename option.

2. Set up a cron job for a separate script that will check for the file and timestamp. If the conditions are met, then send the mail.

Unfortunately it doesn't create a log file, that's what I'm concerned about.
The script is called sendmail Log analyzer, it's been written in PERL and a great way to check your sendmail logs..
You can click here for more information.
Well, the problem is, I have to execute it everytime I want to check the stats. Because It works if only executed at that time, it doesn't log anything..
Do I still have a chance,
Thank you much

does the script write to standard out.

if it does, then your work is done. Just run it from root's cron and the output will be automaticall mailed to root.

if you don't want it mailed to root, I believe that you can set the person to email stdout/stderr to with an evironment var.

or something like this

mail you@whatever.com < `stats /var/log/maillog`

This command doesn't work and gives me the following,

bash: `sendmail_stats /var/log/maillog`: ambiguous redirect

Do you mean that every cronjob executed for the particular user is mailed to the user automaticly??

yes.

everything that goes to stdout and stderr will be mailed to the owner of the crontab.

I will look into the other issue of the ambiguous redirect

try this

stats /var/log/maillog | mail you@whatever.com
