Small script that takes three parameters on the command line: start record, stop record and filename:


Code:
#!/usr/bin/env ksh

awk -v start=${1:-2} -v stop=${2:-3} ' NR >= start && NR <= stop ' $3

If filename is not given, then it reads from stdin.


You can use variables in your sed programme, but you must use double quotes and not single quotes round it:


Code:
read x
 read z y
 sed -n "$z,$y p"  $x

And make sure you have a space between it and the filename ($x)

NAME

       ncakmod - start or stop the NCA kernel module

SYNOPSIS

       /etc/init.d/ncakmod start | stop

DESCRIPTION

       ncakmod is used to start or stop the Solaris Network Cache and Accelerator ("NCA") kernel module.

       When  the  start option is specified at the command-line, the NCA kernel module will be activated for all physical interfaces listed in the
       nca.if file. When the ncakmod command is invoked with the stop option, the NCA kernel module will print the following message:

       To stop NCA, please set the status configuration parameter
       to disable in ncakmod.conf and then reboot your system. See
       the ncakmod.conf(4) manual page for more information.

       Note that in order to properly stop NCA on your system, you must first edit the ncakmod.conf(4) file and set the status field to "disable,"
       then reboot your system.

OPTIONS

       start           Starts the NCA kernel module.

       stop            Describes the current method for stopping the NCA feature.

EXAMPLES

       Example 1: Starting and Stopping the NCA Feature

       The following command is used to start the NCA feature:

       example% /etc/init.d/ncakmod start
