Shell Programming and Scripting

Hi,
How do I change the "From" email address from the header?
It shows
root@localhost.localdomain
as from and I want to change it to something meaningful.

Following will send mail with From as myname@abc.com, To as yourname@abc.com, Subject as My Subject to the id who@abc.com

$ cat mail.txt
From : myname@abc.com
To : yourname@abc.com
Subject : My Subject

Hi,

Test mail.

Regards

My Name.

$ sendmail who@abc.com < mail.txt

Hi,
Is it possible to do it in a single command without using the text file?

echo "test mail command" | mailx -s"testing" shantanu.oak@qmail.com

If I use the above statement, I get a mail with "from" as root@mycompany.com
But if I use the same command from another server, I get localdomain@localhost as "from" email address. Should I add a switch to my mailx command or is there any other setting (O/s level) that needs to be changed?

Hi Shantanuo,

Try like this ( Not tested)

echo "From : myname@abc.com \n test mail command " | mailx -s"testing" shantanu.oak@qmail.com

No. This is not working. The From: header is part of the message body.
Please suggest some other way to achieve this.

or you may try to man mailx to see any option for "from"... some mail/malix can do like
eg. mailx -r fromemailaddress ....

thanks!

None of the options mentioned above did work.
Any other tip will be appreciated.
