Automatic variable assignment inside a for loop

Shell Programming and Scripting

cs1=`echo "scale=8;($css1/$css0)*100"|bc`
cs2=`echo "scale=8;($css2/$css0)*100"|bc`
cs3=`echo "scale=8;($css3/$css0)*100"|bc`
cs4=`echo "scale=8;($css4/$css0)*100"|bc`
cs5=`echo "scale=8;($css5/$css0)*100"|bc`
cs6=`echo "scale=8;($css6/$css0)*100"|bc`
cs7=`echo "scale=8;($css7/$css0)*100"|bc`
cs8=`echo "scale=8;($css8/$css0)*100"|bc`
cs9=`echo "scale=8;($css9/$css0)*100"|bc`

Instead of using the above code, if I use the below to reduce the script size, it is not working. Please help

for i in 1 2 3 4 5 6 7 8 9
do
eval cs$i=`echo "scale=8;($css'$i'/$css0)*100"|bc`
done

in your for loop try to replace with the line (there are 6 simple quote,2 back quote and 2 double quote... don't forget some...)

eval 'cs'$i'=`echo "scale=8;($css'$i'/$css0)*100"|bc`'

Otherwise

for i in 1 2 3 4 5 6 7 8 9
do
t=$(eval echo "\(\$css$i/\$css0\)*100")
eval cs$i=`echo "scale=8;$t"|bc`
done

Since you can't eval in eval :

for i in {1..8}
do
    tmp="cs$i=\$(echo \"scale=8;(\$css$i/$css0)*100\"|bc)"
    eval $tmp
    tmp2="echo cs$i is \$cs$i"
    eval $tmp2
done

I tested & fixed my previous post, use simple quoting for the one line eval :

Give a try to the following :

for i in 1 2 3 4 5 6 7 8 9
do
eval 'cs'$i'=`echo "scale=8;($css'$i'/$css0)*100"|bc`'
done

(don't forget any of the 6 simple quote)
