asterisk users - Jul 2003 - AGI script sample using bash shell script

Hi,
A quick and dirty (aka Rapid Application Developement) AGI script
implement using bash shell. No need to invoke a 10MB perl engine to
process simple asterisk agi scripts. 

I found it to be very useful in learning the AGI interface. For example,
I learn that AGI won't execute the next command until you read the
results from STDIN. 

Enjoy,

Hey does that mean that whole perl script won execute or the next AGI command 
wont execute. Cuz may be I get this problem too.
