How to display HOSTNAME in sendmail?

Shell Programming and Scripting

I have two issues with my script one of which i would like to discuss here.

Its my compulsion to use sendmail .

My sample script

#!/bin/bash

{
        print 'From: Prod@`hostname`.mycomp.com'
        print 'To: me@mycomp.com'
        print 'MIME-Version: 1.0'
        print 'Content-Type: text/html'
        print 'Subject: Usage Report'
        print ''
        print '<html>'
        print '<body>'
        print '<p>Today Usage Report for Server</p>'

        print '</body>'
        print '</html>'
} | /usr/sbin/sendmail -t

Wehn i run the above with debug mode i see that the hostname is not substituted in the From of the email.

i also tried the below in vain

print 'From: Prod@$hostname.mycomp.com'

uname -a
SunOS myhost 5.11 11.3 sun4u sparc SUNW,SPARC-Enterprise

Can you please suggest something that works with both bash and ksh shells ?

You need to use double quotes instead of single quotes. Also, print is not bash syntax but ksh syntax.
