@nextyoyoma:
Code:
awk 'NR<2001{print}' inputfile>> output2

will write 2000 lines into output2, not 1000 as requestedd per OP. Similarly the third awk command.

@OP:
If you have split(1) it's trivial:
Code:
split -l 1000 input outname

On my system, the default is to split every 1000 lines, so actually all you'd need is
Code:
split input outname

but check man split for your implementation.

If you don't have split, here is an awk solution:
Code:
awk '{cnt=int((NR-1)/4); print >> "outname_" cnt}'  input

It will create files
Code:
outname_0
outname_1
outname_2

etc.

interface-order

INTERFACE-ORDER(5)						    resolvconf							INTERFACE-ORDER(5)

NAME

       interface-order - resolvconf configuration file

DESCRIPTION

       The  file  /etc/resolvconf/interface-order is used to control the order in which resolvconf nameserver information records are processed by
       those resolvconf update scripts that consult this file.	(The name of the file is apt because a resolvconf nameserver information record is
       named after the interface with which it is associated.)

       The  file  contains  a sequence of shell glob patterns, one per line.  The position of a record in the order is the point at which its name
       first matches a pattern.

       Patterns may not contain whitespace, slashes or initial dots or tildes.	Blank lines and lines beginning with a '#' are ignored.

       Resolvconf update scripts in /etc/resolvconf/update.d/ that consult this file include the current default versions of  dnsmasq,	pdnsd  and
       libc.   (Actually  they don't read the file directly; they call the utility program /lib/resolvconf/list-records which lists records in the
       specified order and omits the names of empty records.)

EXAMPLE

       # /etc/resolvconf/interface-order
       # Use nameservers on the loopback interface first.
       lo*
       # Next use records for Ethernet interfaces
       eth*
       # Next use records for Wi-Fi interfaces
       wlan*
       # Next use records for PPP interfaces
       ppp*
       # Last use other interfaces
       *
