I'm trying to make this program work and I can't, The script i want must should calculate count of char use in string example : string=good result=g1o2d1 is there any way to write script that calculate exactly count of string like my example or not ? 

 #!/bin/bash
    string=ssstttrrrriiiinnnnngg
    z=$( for((i=0;i<${#string};i++)) do; echo ${string:i:1}; done | uniq -c )
    echo $z
