[Asterisk-Users] Help with shell script for externnotify

[Tom Rymes]

Hi folks,

I am working on a shell script that I can use with the externnotify  
command in voicemail.conf. All is well and seems ready to rock,  
except I can't figure out how to tell the script what e-mail address  
to send the mail messages to. I warn you ahead of time that I am no  
scripting guru.

Basically, I have 14 after-hours mailboxes that all have different e- 
mail addresses. I want this script to parse the mailbox number from  
the original command ($2), and then somehow look that up mailbox's  
address and send an e-mail. It then checks every five minutes to see  
if the message has been retrieved, and escalates things as necessary.  
I don't mind the messy solution of defining all 14 addresses in the  
script itself, though it would be nice to look it up from  
voicemail.conf or something eventually.

I started out using /bin/sh for the scripting, but I assume that this  
is limiting me with what I can do with variables, etc. The only way I  
can think of off the top of my head is to use some sort of nested  
variable, like this subset of my script:

Tmpmail=/tmp/dispatch$$.mail
ext108=user at domain.dom

# Send an e-mail to the appropriate address for this mailbox:
echo "724-6066 $2" > $Tmpmail
echo "New Voicemail Message #$3 in mailbox $2" >>$Tmpmail
cat $Tmpmail | mail -s "$mailsubject" $ext$2

now, the "$ext$2" is what I mean by nested variable. Basically, if I  
can find a way to make this evaluate as $ext108, and then as  
user at domain.dom, I would be a happy camper. Is there any way to do this?

I know that this is technically not an Asterisk question, but then  
again, it is. If anyone has wrestled with this in their own  
externnotify scripts, please let me know

Tom

PS: I know that perl and other scripting languages would be better  
for this, but this seemed simpler to me at the time I started. If it  
can't be done using sh, then I'll start over in perl, but if there's  
a way to make this work, it's the only thing standing between me and  
a script that works exactly as I want.
