echo -e "\033[1mLine0\033[0m"
nr_vhosts=0
nr_var=0
nr_conn_total=0
for ((i=$r1; i <= $r2 ; i++))
do
echo -e "\033[1mLine1\033[0m"


The program echoes Line0, but not Line1, and i get this error:
: syntax erroe: operand expected (error token is " ")
i added the two echo's for debugging, hope that this is the place where the problem is.
