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'

xdg-email

XDG-EMAIL(1)															      XDG-EMAIL(1)

NAME

       xdg-email - command line tool for sending mail using the user's preferred e-mail composer

SYNOPSIS

       xdg-email [--utf8] [--cc address] [--bcc address] [--subject text] [--body text] [--attach file] [mailto-uri address(es)]

       xdg-email {--help --manual --version}

DESCRIPTION

       xdg-email opens the user's preferred e-mail composer in order to send a mail to address(es) or mailto-uri. RFC2368 defines mailto: URIs.
       xdg-email limits support to, cc, subject and body fields in mailto-uri, all other fields are silently ignored.  address(es) must follow the
       syntax of RFC822. Multiple addresses may be provided as separate arguments.

       All information provided on the command line is used to prefill corresponding fields in the user's e-mail composer. The user will have the
       opportunity to change any of this information before actually sending the e-mail.

       xdg-email is for use inside a desktop session only. It is not recommended to use xdg-email as root.

       See http://portland.freedesktop.org/EmailConfig for information on how the user can change the e-mail composer that is used.

OPTIONS

       --utf8 Indicates that all command line options that follow are in utf8. Without this option, command line options are expected to be
	      encoded according to locale. If the locale already specifies utf8 this option has no effect. This option does not affect mailto URIs
	      that are passed on the command line.

       --cc address
	      Specify a recipient to be copied on the e-mail.

       --bcc address
	      Specify a recipient to be blindly copied on the e-mail.

       --subject text
	      Specify a subject for the e-mail.

       --body text
	      Specify a body for the e-mail. Since the user will be able to make changes before actually sending the e-mail, this can be used to
	      provide the user with a template for the e-mail.	text may contain linebreaks.

       --attach file
	      Specify an attachment for the e-mail.  file must point to an existing file.

	      Some e-mail applications require the file to remain present after xdg-email returns.

       --help Show command synopsis.

       --manual
	      Show this manualpage.

       --version
	      Show the xdg-utils version information.

ENVIRONMENT VARIABLES

       xdg-email honours the following environment variables:

       XDG_UTILS_DEBUG_LEVEL
	      Setting this environment variable to a non-zero numerical value makes xdg-email do more verbose reporting on stderr. Setting a
	      higher value increases the verbosity.

EXIT CODES

       An exit code of 0 indicates success while a non-zero exit code indicates failure. The following failure codes can be returned:

       1      Error in command line syntax.

       2      One of the files passed on the command line did not exist.

       3      A required tool could not be found.

       4      The action failed.

       5      No permission to read one of the files passed on the command line.

CONFIGURATION

       Visit http://portland.freedesktop.org/EmailConfig for information how to configure xdg-email to use the email client of your choice.

EXAMPLES

       xdg-email 'Jeremy White <jwhite@example.com>'

       xdg-email --attach /tmp/logo.png 
		 --subject 'Logo contest' 
		 --body 'Attached you find the logo for the contest.' 
		 'jwhite@example.com'

       xdg-email --subject 'Your password is about to expire' 
		 'jwhite@example.com' 'bastian@example.com' 'whipple@example.com'
