Read line with particular number of lines
Hi all,

I have a file sample.txt
Code:
abc
asd
adf
daf
adw
add
adv
wdf

I want to control the number of lines to read

Like if i give input as ./script_name 2 5

required output
Code:
asd
adf
daf
adw

ultimate i need a script which reads the particular number of lines and
runs nohup automatiocally in bash

Code:
nohup script_name asd &
nohup script_name adf &
.........


thanks
