Hi

I have a file & always I need to remove or delete last 2 lines from that file. So in a file if I have 10 lines then it should return me first 8 lines.

Can someone help me?

sed '$d' file | sed '$d'

sed 'N;$!P;$!D;$d' myFile

Hi Vgersh

If I use the command you provided, it removes the last 2 records. But when this output is redirected to the other file, it shows the last 2 lines on the console & copies intended data to the file excluding last 2 records.

How to get rid of these last 2 appearing lines?

how exactly are you redirecting?
it works just fine here.

sed 'N;$!P;$!D;$d' myFile > myFile_new
