Поп! _Проблемы Realtek PCI ОС 20.04

Awk раствор:

awk '/echo "New Cell"/{    # on encountering line with `echo "New Cell"` 
         if (sum) {        # if calculated sum exists
             c = NR - n;   # get number of processed records
             printf "%s Count = %d, average = %.2f\n", $0, c, sum/c;
             sum = 0
         } 
         n = NR + 1        # get the initial record position/number
     }
     n{ sum += $9 }' file

Выход:

echo "New Cell" Count = 4, average = 4.19
echo "New Cell" Count = 10, average = 8.89
echo "New Cell" Count = 2, average = 2.20
