запуск Гетстрима, автоматическое отлавливание ошибок типа:
вылет процесса, неактивность процесса, вещание нуля пидов...используется статистика вывода гетстрима

собсна сам скрипт запуска гетстрима+newcs+sascng:

#/home/nast/start
newcs.x86_64 &
sleep 5
insmod /win1/open-sasc-ng/r77/dvbloopback.ko num_adapters=3 &
sleep 5
/win1/open-sasc-ng/r77/sasc-ng -j 0:3 -j 1:4 -j 2:5 --cam-budget -b 20M --cam-dir /etc/camfiles/ &
/home/nast/getstream

расшифруем:

#/home/nast/getstream
sleep 11
nohup /win1/getstream/getstream2-20081204/start1 >start1.out &
sleep 11
nohup /win1/getstream/getstream2-20081204/start2 >start2.out &
sleep 11
/config_getstream/21 -dd &>getstream21.out &
nohup /win1/getstream/getstream2-20081204/start3 >start3.out &
