bind statistic file not cleared after the script executes

Just my +2 Cents. The script doesnt’ truncate the stats file from rndc stats command. As result after several years I noticed that /var/named/data/named_stats.txt increased to 1,5G and when the script within icinga tries to run this script it take about 2 minutes before tac command load all the file into the memory to perform awk action. Of course icinga tries to kill the script after 60 seconds timeout and produces error. I have modified a script a little a bit, so the named statistics file will be purged everytime after check_bind.sh is executed:
