Email headers in shell script

anjaan · 07-07-2004, 12:52 PM

Hi all,

I am trying to write a script that will send email to me every few hours. But I need to customize subject and headers. How will I do this in a bash script.

If someone can tell me how to wait for few seconds and then run the next line in the script that will be useful too.

Thanks in advance

You do not tell what program you are using to mail, so I'll use mailx for the example.
Something like this works:

mailx -s "$subject" $maillist

Waiting (sleeping) for a certain amount of thime:

sleep <secs>, where secs is amount of seconds to sleep. If you sleep for long times at once, there wil be a deviation.

I am using Sendmail. Actually, I need something that will create an interactive telnet session

telnet 127.0.0.1 25
helo domain.com
etc
etc

Maybe a 'here document' construct could do what you want.

This site has some examples of how it works:

I'm not a telnet user (to insecure for my taste), so I'm not sure if the login in part can be done this way.
