UNIX for Dummies Questions & Answers

Hello,
I am trying to use sendmail with spesific usage

I am trying to tail a file and send it from an address to my personal mail

I am doing so with this command:
tail -c 60000 test | sendmail -f sender@domain.com my@mail.com

This is working great.
I am trying to add this command a subject. so I will be able to add a title to the emails in order to filter them in my mailing applications

Is it possible? I havent found anything about it using the forums
and the simple echo "Subject: bla bla" does not work on this context..

Thanks for the help!

you would probably be better not to use sendmail directly, but to use a more user friendly mail utility like mailx e.g.:

Code:

#  tail /var/adm/messages  | /usr/bin/mailx -r "sender@domain.com" -s "bla bla"  my@mail.com

HTH

I got an error that -r option is invaild, thats one of the reasons im using sendmail
Any suggestion?

p.s
using mailx-8.1.1-44.2.2 on CentOS 5.5

Code:

 
# tail -c 60000 test | sed 1i"Subject: bla bla" | sendmail -f sender@domain.com my@mail.com

Thank you very much, this is working perfectly.
