Post Removing the first and last lines in a file

Hi Gurus,

I'm a little new to UNIX. How can I do remove the first and last line in a file? Say, supppose I have a file as below:
Code:
Code:
1DMA                 
400002BARRIE         
401002CALGARY/LETHBRI
402002CARLETON       
500001PORTLAND-AUBRN 
501001NEW YORK, NY   
502001BINGHAMTON, NY 
9DMA     255
I want to remove the line 1 and line 8 ( one which starts with '1DMA' meaning it is a header and the trailer which starts with '9DMA'). My final result should be as below:


Code:
Code:
400002BARRIE         
401002CALGARY/LETHBRI
402002CARLETON       
500001PORTLAND-AUBRN 
501001NEW YORK, NY   
502001BINGHAMTON, NY
Your help and inputs are greatly appreciated!

Many thanks,
Naveen.

If your file is very very large, you can use awk
Code:
awk 'NR > 2 {print line} {line = $0}' file > newfile
