It finds(greps) lines having PAY in $FOR_FIL(file) and gets the characters from 92-106 and gives the last 'i' lines as the output.
Instead of cat $FOR_FIL, you could use - grep PAY $FOR_FIL which is a good way of scripting. |

It achieves the same functionality. May be you should 'man grep' and see for yourself.
