Hi Keke.

I can not understand the logic of the program.

My file
To: 375291111111 To: 375292222222 Hello!

The examples do not help.

Script
file="aa" count=`cat $file | grep '^To: ' |wc -l` message=`cat $file |tail -n -1` if [ $count -gt 1 ]; then i=0 while [ $i -lt $count ] do i=`expr $i + 1` head -n $i "$file" | tail -n -1 > $i.msg ( echo "Alphabet: UTF-8" && \ echo && \ echo "$message" ) >> $i.msg done rm $file fi

That script works but ignores any additional headers. Actually, only To: headers are allowed, other headers will break the logic.

If you want to implement "multiple recipients" feature to your smsd setup, see this topic: Multiple recipients in single SMS file.

Variable "headers" is fundamental in sending SMS to multiple recipients?
What is it should take?
Sorry, I'm only two weeks teaching bash scripts.
I do not understand everything in the examples.

Of course all headers other than To: are meant to use for every message. For example, if the message has Flash: yes, all recipients should get a flash message.

About scripting in general, this is very good: Advanced Bash-Scripting Guide

You do not understand ...

I could not realize the multi sending.
Now it worked.
Thanks Keke.
Good luck.
