Tools counter file
What you are doing is storing the counter number in a file call my_cntr. Every time the file is run, the counter is increased by one. This will handle your counter issue. You then just need to mix your other requirements in with this code section.
There are two echo's to the screen that you can remove; they are not essential to the program execution. They are the "#print to screen" lines.


Code:
#! /bin/bash
# to read a counter

if [ -s my_cntr ]
# counter file exists
   then
      last_val=$(cat my_cntr)
      echo "current: "$last_val  #print to screen
      next_val=$(($last_val + 1))
      echo "next: "$next_val   #print to screen
      echo "$next_val" >my_cntr
   else
      echo "1" >my_cntr
fi
