New to unix and learning the talk and walk of it. I am writing a script in .ksh and have a requirement of sending a mail with a message. Currently using this command in my script:
mailx -s"File not found" abc@def.com
This command helps me having a subject and the recipient name. My question is how can I write a message along with it. Cause every time i run the script it pauses and asks me to enter the message and then executes, I want to pre-include the message so the script would not pause in between.
echo 'Message body goes here' | mail -s 'subject line goes here' email@provider.com
Try this on the command line or inside a script:
echo "This is the message." | mailx -s "Subject" abc@def.com
You can use pre-defined messages from files:
cat message.txt | mailx -s "Subject" abc@def.com
Alternatively to mailx (mentioned in the other answers) you can also use sendmail:
cat <<EOF | sendmail -t
To: recipients-mailaddress
From: your-mailaddress
Subject: the-subject
mailtext
blabla
.
EOF
Perhaps you need to add the full path to sendmail if it's not in your path. E.g. /usr/sbin/sendmail or /usr/lib/sendmail.
Update:

as mailx takes the body as input on stdin you can pipe the body to it:
echo "Hello World" | mailx -s"File not found" abc@def.com
Or use a here document
mailx -s"File not found" abc@def.com << END_TEXT
Hello World
END_TEXT
If you also want to add attachment to the you want to send. Here you go:
echo 'Type Message body' | mailx -s 'Type subject' -a path/filename.txt email@provider.com
EXAMPLE:
echo 'PFA report' | mailx -s 'Today's Report' -a `path`/report1306.txt xyz@gmail.com
Define the mailcontent beforehand and do it like this:
mailx -s"File not found" abc@def.com < mailcontent
