I write the attached notification email in UNIX shell script on Solaris10 server. The email that I receive only shows the subject correctly but the Body of the email is blank. What am I doing incorrectly?
#!/bin/sh
    tmp=/tmp/mail-body-`date +%F`;
    touch $tmp && chmod 600 $tmp;
    TO='me@myco.com';
    CC='me@myco.com';
    FROM='me2@myco.com';
    SUBJECT='ETL JOB2';
    MIMEVersion='1.0';
    CONTENTType='text/html; charset=us-ascii';
    BODY='ETL successfully completed';

    echo Sending the mail.
    echo -e "To: $TO" > $tmp;
    echo -e "Cc: $CC" >> $tmp;
    echo -e "From: $FROM" >> $tmp;
    echo -e "Content-Type: $CONTENTType">>$tmp;
    echo -e "MIME-Version: $MIMEVersion">>$tmp;
    echo -e "Subject: $SUBJECT">>$tmp;
    echo -e "Body: $BODY">>$tmp;

    /usr/sbin/sendmail -t < $tmp;

    rm -rf $tmp;

Try to insert a blank line before the body.

"Body:" tag is not required.

If you add "Body:" in the message, that string will also be included in the message. What is required is a blank line after the "Subject:" and before the actual message body.

Looks like you're overcomplicating things.  You don't need to set a mime type, or content type.  As subratabiswas said, just put a blank line between the subject and body.  

    echo "To: $TO" > $tmp;
    echo "Cc: $CC" >> $tmp;
    echo "From: $FROM" >> $tmp;
    echo "Subject: $SUBJECT">>$tmp;
    echo >>$tmp
    echo  "$BODY">>$tmp;

Many thanks for all the help.
    echo -e "Subject: $SUBJECT">>$tmp;

    echo -e "Body: $BODY">>$tmp;


Just adding the extra blank line between the above two lines worked.
But actually I have been trying to put the content of one text file into the $BODY variable.
I tried

    /bin/cat /usr/home/w12345/templog.txt >> $BODY
    echo -e "Body: $BODY">>$tmp;

But cannot make it work. What is the correct syntax here? Thanks.

You are trying to assign the contents of the whole file into the vriable and then trying the echo that variable into the mail file. Instead, do the straight and easy way; just cat the content of the file into the mail file

echo "To: $TO" > $tmp;
echo "Cc: $CC" >> $tmp;
echo "From: $FROM" >> $tmp;
echo "Subject: $SUBJECT">>$tmp;
echo >>$tmp
/bin/cat   /usr/home/w12345/templog.txt   >>   $tmp

Thank you..

Yes the
/bin/cat   /usr/home/w12345/templog.txt   >>   $tmp

works somewhat..

Problem is that the email content cannot recognize the newline characters in the templog.txt file. So the contents of /usr/home/w12345/templog.txt  come as single line in the email.

If I echo >>$tmp it shows the contents correctly.

So I need to make some changes in the email header ??
CONTENTType='text/html; charset=us-ascii';  ??

The email I receive is in HTML format (gmail).

If you decide to send HTML and maintain the typed format, you may use <PRE> tag around the message body; HTML by itself processes whitespaces in its own way.

You may consider removing content type from the email header altogether. It does not make sense to indicate message type = 'HTML' and not having a real HTML body.
