UNIX for Dummies Questions & Answers

Hi,

How can i send a mail to a group in Linux? for example, I want to send a notification mail to 20 people and I want to create a group of these 20 people and want to send them the notification

pls help me in this.

You can setup a group mail alias. Try "man aliases" for details.

Thanks for quick reply. But, can you please explain how can I implement the aliases in the following script?
+++++++++++++++++++++++++++++++++++++
#!/bin/bash
ps aux|grep DPROPR > /dev/null
if [ $? -ne 0 ]; #if not running
then
mail -s "DPROPR is not running" email ids
fi
+++++++++++++++++++++++++++++++++++++

I want to send the mail to a group if the script doesn't find DPROPR process runnning.

On the "mail" statement instead of sending the email to "user1" "user2", etc, you can create an alias group1 which contains the list of users, and then simply send the email to "group1"

You mean, in /etc/aliases file I can add the line such as:

group1: abc@xyz.com, bcd@xyz.com,etc

and include the following command in the script:

sendmail "hello" group1

will this work?

Thanks in advance for your reply.

Yes - the group entry is correct. And there is then two common ways of sending the mail, either by using "mail":

Code:

mail -s "subject" group1 < email_file

Or by calling sendmail (slightly different because you have to create the envelope headers), for example:
The Answer Gang 65: sendmail

Thanks for reply..

I am having another issue, when I am trying to send a mail to my own email from the Linux machine (I am running this machine as a virtual machine using vmware), I am not receiving any mails.

but, when I am trying to send a mail through another linux machine, I am receiving the mails.

So, can you pls let me know, how can this issue be resolved?
