#initializing result variable to zero res=0

#reading each values from the runtime parameters for i in $* do # if any of the values are negative, then changing it to positive by multiplying by one if [ "$i" -lt 0 ] then why it is giving me 0 instead of 58

help me

i=$(expr $i \* -1); fi #adding each values one by one to result variabe res=$(expr $i + $res); done #displaying the result echo $res;
