Re: [Asterisk-Users] AGI script sample using bash shell script
[EMAIL PROTECTED], During development of the bash script, I have problem reading the whole string from the STDIN and I notice the next command won't get executed. Notice the "case statements" that I have to implement to handle the read line. This is because normally Asterisk will return one line "200 ...". However, if the command is not properly written, like "SAY NUMBER" instead of "SAY NUMBER 123 \"\" ", then Asterisk will return multiline usage information back ... something like 520-blah blah blah\n blah blah blah blah\n ... 520 End of ...\n The next command will not get executed until you read the last line. Suggestions, play around with this: echo "SAY NUMBER 123 \"\"" < Asterisk says 123 read line< Asterisk return 200 echo "SAY NUMBER 123" read line< Asterisk return usage info. but we only read one line echo "SAY NUMBER 345 \"\"" < this will not be executed read line Hope this helps, Sunny Woo Solutions Consultant Avantnix > Hey does that mean that whole perl script won execute or the next AGI command > wont execute.

[Asterisk-Users] 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,
