Hi.

I am trying to make a script that starts another script upon the recieve of a email.
For ex. When i send a mail with a string killuser abc, to a typicall adress (of the unix machine) it must execute a script that kills the user abc..

can anyone help ?

thanks

Warning -- this kind of operation can be extremely dangerous. In principle it provides a way for just about anybody to perform these kinds of operations on your machine.

If you still choose to do it, the script that will handle this should contain safeguards to (try to) avoid malicious or inadvertant problems.

Write the script myscriptname.pl so that it reads from stdin and operates based on what it reads. Then, in the file /etc/aliases, add a line like this:

userid: "| myscriptname.pl"

Any message sent to userid@hostname will be read by the script and handled appropriately.
