Substring command not working in solaris kshell

I am trying to use the following command to extract a substring from a string : 

propertyPath=$(echo $path|awk '{print substr($0,3,$index)}')

However the command does not pick up the value of the $index variable and therefore does not return a valid substring.

Solution

  • This would work:

    propertyPath=$(echo $path|awk '{print substr($0,3,'$index')}')

    or

    propertyPath=$(echo $path|awk -v index=$index '{print substr($0,3,index)}')
