send email issue in unix
Hi,

I am trying to send the contents of a file as email in unix.I am using the below code to do this.But when i get the email i see that SUBJECT and TO is blank. Can you please let me know why it is blank? Also the FROM address comes as admin@myhost. Is there any way i can set FROM to user defined value?
Code:
    SUBJECT="Automated Security Alert"  
    TO="xyz@abc.com"  
    MESSAGE="/export/home/admin/bin/getStatus2.txt"  
    /usr/bin/mail -s "$SUBJECT" "$TO" < $MESSAGE

thanks
vignesh

This question is Operating System specific.

Please tell us what Operating System and version you have and what Shell you are using.

I am using bash shell and SunOS

There are umpteen versions of SunOS (none of which come with "bash" as standard), but my guess is that you should be using "mailx" not "mail".

Code:
SUBJECT="Automated Security Alert"  
    TO="xyz@abc.com"  
    MESSAGE="/export/home/admin/bin/getStatus2.txt"  
/usr/bin/mailx -s "$SUBJECT" "$TO" < $MESSAGE

Thanks mailx worked! Can you please let me know whether if there is any way i can set FROM to a user defined value?

It should be the "-r" switch on the "mailx" command line, but see "man mailx" on your system. Beware that this sort of mail spoofing can result in virus scanners eating the mail.
