Danmero already provided an awk solution.

Here's another one:

Code:
awk 'NR!~/^[13]$/' infile

Code:
awk '(NR != 1 && NR != 2) {print $0}' < filename>

, it should be &&

Guys, i think i have not explained myslef well..

I dont want an AND (&&) condition. I want an OR (||) condition.

The problem is awk is working with AND condition but it is not working with || condition
When i am using || condition, it is giving all the records instead of the two records i needed.

Hope i made myself clear

So what exactly is wrong with this solution? It's just boolean logic: !(line 1 or line 3) == !line 1 and !line 3

What should be the output given the following input:
Code:
zsh-4.3.10[t]% print -l line{1..5}                               
line1
line2
line3
line4
line5

Which lines should appear?

Given your last comments, I suppose that you don't want this:

Code:
zsh-4.3.10[t]% print -l line{1..5}|awk 'NR !~ /^[13]$/'
line2
line4
line5
