If this is bash, there's no need for a command, just use parameter expansion..
First get the string into a variable. You may want to use "string=$(head -1 yourfile)", I just did it differently as an example. Then the parameter expansion is used to cut out portions of the variable using two numbers to locate the substring you want. In the first one, it cuts out 11 characters from the left and leaves in the next 8. In the second one, it cuts out 9 and leaves the next two. Put a dot between them and you have the filename you need.
