Shell Programming and Scripting

Thanks for replying back.

The file does not have header fields.
Suppose if the file has only 1 row like following:

Manual m456@hotmail.com

then it's not sending mail to that id. ( i believe it's skipping first row).
I tried removing NR>1, but still it does not work.

But if the file has more than 1 rows like following:

Execution din098@gmail.com
Artistic din098@gmail.com
Graphic din098@gmail.com
Manual m456@hotmail.com

then it would send mail to both the id's (m456@hotmail.com and din098@gmail.com ).

Could you please help me with it. Your help is highly appreciated.

Works for me!

Here is the data in file: input_file

Code:

$ cat input_file
Manual m456@hotmail.com

Here I am running awk commenting out the mailing part:

Code:

$ awk '{ print $2 | "sort | uniq" } ' input_file | while read mail_id
do
        awk ' BEGIN { print "Assigned Values: " } /'$mail_id'/ { print $1 } ' input_file ###| mailx -s "Group Info" ${mail_id}
done
Assigned Values:
Manual
