UNIX for Dummies Questions & Answers

Hi

Can any one help me out ?

I am trying to send an autogenerated mail with an attachment to bulk of users using 'MAILX' and 'UNENCODE' . I have used it as follows

X " ( cat /sastemp/body.txt; uuencode Test.xls.gz Test.xls.gz ) | mailx -s 'Testing' ' abcd@yahoo.com , efgh@gmail.com ' "

But the problem here is, we dont want to hard code the email ids in our program. So can any one let me know how to sort it out with out hard coding the email ids and sending the mail to bunch of people.

Thanks in advance.

Regards.

Depends on the way you want to feed your script with email adresses.

One possible way is, to use just replace the emails in your script by using the variable

Code:

$@

or

Code:

$*

where for this script it might not make a difference which of both you use. So if you call your script, you can use it for example like

Code:

./mailscript.ksh garry@b.org jupp@bla.com mike@fodder.net

If you want get them from a file, just use a while/read or for/cat construct maybe.

Then how do you propose to know where to send them?

You should use a $@ in your script and pass the emailid as parameters to the script.

Hi all

Thanks for you valuable inputs.

My objective is to keep all the emails IDs in a file or dataset and use a unix command which retrives the email ids from that file/dataset and send it to respective users. Currently 100 users are there and every month some of the users get added to the existing users list. So every time it is difficult to change the code. To avoid this I want to create a file or dataset where we can keep or modify the users on monthly basis. i have tried using 'CAT' but unable to succeed. Can you please give the clear sintax of the same.

Thanks for your time.

I don't know how much parameters (ie. email addresses) your mail client will be able to process

Your list should look like:

Code:

address1
address2
address3
address4
address5
...

Code:

cat addressfile |\
while read ADDRESSES; do
   read ADDRESSES
   (echo "here is the data!" | uuencode datafile datafile) mail -s "mysubject" ${ADDRESSES}
done

In this example mail will be invoked for each single line of input. So you will not have to fear that your mail client has problems with processing too many addresses ie. parameters at once.

Hi

Thanks for your inputs.

The code looks fine but had a small query in my mind regarding the code.

The addressfile you have mentioned should be in which format(.txt???).

Can you please let me know whether the addressfile and ADDRESSES should be with the same name??

Thanks
