RE: returning result from exec_program TEC 3.9

I had some issues with exec_program_local (TEC 3.8 FP02) as well as other
methods that I tried .... So at the end I ended up with handling this issue
directly in the script (tec_task).
Basically, I am checking for the result of the execution  (0 or non-zero
result of the execution) and sending it back to TEC via another event where
I reference back date_reception and event_handle (to find original event
upon which the task was spawned). Date_reception and event_handle are
variables passed to exec_task.
Maybe not very efficient but it works ...

Can't do it with exec_program/exec_task they are run in a different
process (TEC_Task).  You have two options:

1) Use the undocumented shell predicate (not recommended)
2) Use exec_program_local and it will generate another event when the
program completes with return code and feedback information.  Then in
another rule process the TEC_Task event that is sent back in.

Subject: [tme10] returning result from exec_program TEC 3.9

Hi List,

Is it possible, and if so could somebody give me some pointers on the
predicates and structure to use to be able to return a result from a
perl script, triggered via exec_program, back to the rule so that the
rule can subsequently proceed dependent on the result returned via the
script ?

many thanks

Dave
