Smart email bot?

[KClaisse]

I need a program that will run certain scripts/programs depending on contents of the email.

Example:

I send an email to statusbot@mydomain.com with the body saying space. The email bot then runs this bash script:

#!/bin/bash

#Percent of space used
pct_used=$(df -h | grep hda1 | grep  -o [0-9][0-9]'%'| tr -d '%')

#Gigabytes free
gb_free=$(df -h | grep hda1 | egrep -o '([0-9].?[0-9]?G)( {2})[0-9][0-9]?[0-9]?%' | sed -n 's/[0-9][0-9]%//p' | tr -d G | tr -d " ")


echo "Disk '/dev/hda1' is $pct_used% full with "$gb_free"GB's of unused space." > _spacemail.txt
mail -s "Hard Drive Space Alert" statusbot@mydomain.com  mycell@cellprovider.com < _spacemail.txt
rm -f _spacemail.txt

So I need the bot to interpret the contents of the email, and run the needed script. This system is going to be used by my cellphone, allowing me to keep track of my server while away from an internet source. I would rather the email bot be able to run a script, then reply with the output, which would allow me to use a cellphone other than my own, but the above scheme would be much easier to implement. So if anyone can think of how to auto-reply with a scripts output, that would work too.

Is this possible?

Anyone? I've been searching on my own and I still can't find anything.

Hi,
Threre is a web site at bots.htm: (¯`·.¸(¯`·.¸ Searching Bots ¸.·´¯)¸.·´¯) - which shows you the code for bots to read pages and extract information, which you can use. Perhaps you can modify one to suit your needs. Many of them use Perl which is ideal for then running a script.

Now that I think about it I'm sure I can write a simple bash script that would serve my purposes, all I need to know is how to get the contents of them email. I've tried using /bin/mail but I can't figure out how to operate it form a script.

I have been looking into MUTT - text based e-mail reader editor etc.
MUTT supports regular expressions pattern matching, and many other things. It interfaces with Mozilla as well. Here is a link:

Well here's what I did:

created a new user named statusbot
created a file name .forward in statusbot's hom dir with this in it:

/home/statusbot/mailmon/mail.txt,"|/home/statusbot/mailmon/mailmon.sh"

mailmon.sh contains this:

#!/bin/bash
dPATH=/home/statusbot/mailmon
for line in `cat $dPATH/mail.txt`
do
        from=$(cat $dPATH/mail.txt | grep From: | grep -v Message-ID | grep -v Return-Path:| egrep "[a-zA-Z0-9_.-]+@([a-zA-Z0-9-]+\.){1,}([a-z]){2,4}" -o|grep -v statusbot)
        case $line in

                uptime|Uptime )
                UP=$(uptime | egrep "([0-9][0-9]:?){3}.up.[0-9]{1,4}.days?" -o)
                echo $UP > $dPATH/out.txt
                ;;

                speed|Speed )
                curl http://router:rangers@192.168.2.1:8000/speed.cgi -s -o $dPATH/rawpage.tmp
                up=$(cat $dPATH/rawpage.tmp |grep \<h3\> | sed -n 's/<h3>//p' | sed -n 's/<\/h3>//p' | grep Up)
                down=$(cat $dPATH/rawpage.tmp |grep \<h3\> | sed -n 's/<h3>//p' | sed -n 's/<\/h3>//p' | grep Down)
                rm $dPATH/rawpage.tmp -f
                echo -e "$down\n$up" > $dPATH/out.txt
                ;;

                "hi" ) echo "Why hello to you too" > $dPATH/out.txt
                ;;

                esac
done
mail statusbot@kylesplace.org $from < $dPATH/out.txt
rm -f $dPATH/out.txt
rm -f $dPATH/mail.txt
echo done
exit 0

Than I can just keeps adding cases to suit my needs. Works perfect for me.
