I am trying to write a simple bash script which will function as a mailing list,
using the mail function and a seperate list of emails. For example:

maillist
person2@mymail.co.uk
person2@mymail.co.uk

newletter
This is a test newsletter

How do I use cat and mail commands to send a copy of the newsletter to all the emails in the email list. ?

cat newsletter | mail???

Something like this should work:
#!/bin/bash
IFS="
"
for address in `cat maillist`;do
cat newsletter | mail $address -s "Here is your newsletter"
done

One way is
mail -s "Da Subject" DaUser@domain.com < newsletter

You can use some sort of for loop to replace DaUser@domain.com with a user in a list you have.

Hallo,
I m a shell scripting newbie, and i m trying to create a shell script that search for some files names 'script', those files are located in the subdirectory of a directory named "folder", and for each file founded, i have to show the directory (full path) where the file was founded and pipe the file to some program.
the script must be something like that:

for each file found in the subdirectory tree of "folder"
do
"show the full path where the file was found, without the file name, like /root/folder/images"
enter this directory already showed ($cd directory)
"pipe the file to a program"
done


Thanks for help!!
