help writting an automated mail script?

pachakutek · 07-17-2006, 05:09 PM

Hi there,
Newbie here...I need to write a script that gathers info from system (run certain commands) and then delivers this info via an automated email. Does anybody know where I can find some kind of template for this? or even better.. can someone give me some detailed advice?.
Thanks.

I've got some Perl code that does that sort of stuff, but need more specific details of what sort of sys info you want to gather.

just use batch, at or cron

e.g:
echo script_name | at 10pm

Thanks for your input. Well the I need to gather info about the daily check-ins to our subversion server, and report them automatically every day. I'm looking for some script (or template) already written and just put in the commands I needed to run. Thanks any input will be greatly appreciated.

The following might be a starting point to do what you want:

Code:

#!/bin/bash
(
/usr/bin/date
/usr/bin/uptime

echo
echo "Current users:"
/usr/bin/who

echo
echo "Scan of localhost:"
/usr/local/bin/nmap -sT -sV -P0 localhost

echo
echo "Current connections:"
/bin/netstat --inet -ape
) 2>&1 > /var/www/html/reports/status.log

(
echo "To: Steve <mail@somewhere.com.au>"
echo "From: System Status <noreply@somewhere.com.au>"
echo "Subject: System status"
echo
echo "Ready for download at <http://www.somesite.com.au/reports/status.log>."
) 2>&1 | /usr/sbin/sendmail -t

It's easy enough to either wrap the output in html and make it a web page, or to redirect the output to mail so that the email contains the command output. If you do wrap the output in html, you should also change the output of the commands so that tag characters like "<" & ">" are converted to "<" & ">". You can use sed for this, e.g.:

Code:

/usr/bin/ps auxfww | /bin/sed -e s/</\&lt;/g -e s/>/\&gt;/g

As I said, just a starting point - hope it helps...

Thank you. It definitely somewhere to start. I'll post progress later on. Thanks again.

It's quite easy,

basically:

Code:

cat file | mailx -s subject user@box
