I was trying to read a file, add some user defined content to it and send out an email , I did find out a way to achieve this, but looking at the code, it looks a bit crude to me, can you guys point out a more efficient way of writing this?

Here is the my Input file id_list.txt
Code:
Bob
Marcus
Adam

And this is what I expect to be sent in the email
Code:
This is a test email 

This is an email to notify you that the following ID's are going to expire in 1 week 

Please change the password for "Bob" to avoid being locked out.

Please change the password for "Marcus" to avoid being locked out.

Please Change the Password for "Adam" to avoid being locked out.

And this is what I wrote
Code:
EMAIL_TEXT1="This is a test email"
EMAIL_TEXT2="This is an email to notify you that the following ID's are going to expire in 1 week"
echo 
{
echo $EMAIL_TEXT1 $EMAIL_TEXT2
{
while read userID;
 do 
 { echo -n " Please change the password for " && echo -n \"$userID\" && echo " to avoid being locked out.\n"; }
done < id_list.txt
} }> final_op.txt
mutt -s "Test Email" "karthik@xyz.com" < final_op.txt

Can someone point out a better way to write this? Also can you also explain, instead of writing the file to the final_op.txt , if i pipe it to the mutt command, the email comes up in a non formatted way, that is the text inside the while loop comes up in a single line. But if i seperate it out it comes as I have mentioned in the expected output .

Thanks,
Karthik
Try:
Code:
EMAIL_TEXT1='This is a test email'
EMAIL_TEXT2="This is an email to notify you that the following ID's are going to expire in 1 week" 
( printf "%s\n\n%s\n" "$EMAIL_TEXT1" "$EMAIL_TEXT2"
  while read userID
  do    printf "\nPlease change the password for \"%s\" to avoid being locked out.\n" "$userID"
  done < id_list.txt
) | mutt -s 'Test Email' 'karthik@xyz.com'

NAME
ftpmail - FIFO-based Perl script for sending email based on proftpd TransferLog SYNOPSIS
ftpmail [ --help ] [ --fifo fifo-path ] [ --from email-address ] [ --log xferlog-file ] [ --recipient email-address ] [ --subject email- subject ] [ --smtp-server server-address ] [ --attach-file ] [ --auth smtp-auth-info-file ] [ --ignore-users regex-pattern ] [ --watch- users regex-pattern ] DESCRIPTION
ftpmail is a Perl script designed to read ProFTPD's TransferLog log entries, watching for uploads, and to send an automatic email notifica- tion when uploads occur. To use ftpmail , you configure your proftpd daemon to write its TransferLog to a FIFO; the ftpmail program is a FIFO reading program which then processes those log messages. OPTIONS
--help Display a short usage description, including all available options. --attach-file If used, this will cause a copy of the uploaded file to be included, as an attachment, in the generated email. --auth smtp-auth-info-file Configures the path to a file containing SMTP authentication information. The configured file should look like this: user username password password --fifo fifo-path Indicates the path to the FIFO to which proftpd is writing its TransferLog. That is, this is the path that you used for the TransferLog directive in your proftpd.conf. This parameter is REQUIRED. --from email-address Specifies the email address to use in the From email header. This parameter is REQUIRED. --ignore-users regex-pattern Specifies a Perl regular expression. If the uploading user name matches this regular expression, then an email notification is NOT sent; otherwise, an email is sent. --log xferlog-path Since this script reads the TransferLog using FIFOs, the actual TransferLog file is not written by default. Use this option to write the normal TransferLog file, in addition to watching for uploads. --recipient email-address Specifies an email address to which to send an email notification of the upload. This option can be used multiple times to specify multiple recipients. AT LEAST ONE recipient is REQUIRED. --smtp-server server-address Specifies the SMTP server to which to send the email. This parameter is REQUIRED. --subject subject Specify a custom Subject email header for the email sent. The default Subject is: User '$user' uploaded file '$file' via FTP --watch-users regex-pattern Specifies a Perl regular expression. If the uploading user name matches this regular expression, then an email notification is sent; otherwise, no email is sent. FILES
