NO JOY Looping a Dialplan System() Command

[John Squared]

Hello,

I'm hopijng someone can explain to me how I would go about running the following command (python) to run in bash in it's own process and set it to run X amount of times?

exten => s,n,System(gvoice -b -e ${GVACCT} -p ${GVPASS} send_sms ${SMSNUM} "${utterance}")

I've tried things like the following but still can't understand how this is done:

exten => s,n,System(n=0; while [[ $n -lt 2 ]]; do gvoice -b -e ${GVACCT} -p ${GVPASS} send_sms ${SMSNUM} "${utterance}"; n=$((n+1)); done)

exten => s,n,System(run -n 2 'gvoice -b -e ${GVACCT} -p ${GVPASS} send_sms ${SMSNUM} "${utterance}"')

Basically I just want to have pygooglevoice run my command twice so that two text messages are send instead of just one.

Any and all information will be greatly appreciated. Thanks!
