Question: Is there any way you can alter the default value of FNR and then output it to the screen.

I have tried:

```
(piped output....) | awk '{FNR=0} {print $0, FNR}'

```

I am hoping that solution will be interhangeable with NR.

Answer: 
Why not declare your own `offset` variable:

```
(piped output....) |  awk 'BEGIN {offset=2} {print $0, FNR+offset}'

```
```
$ awk 'FNR > 2 {print $0, FNR}' yourfilename

```

FNR isn't necessarily interchangeable with NR. If you specify multiple files, FNR reinitializes to zero before each file. NR doesn't.
