Thanks junior-helper for the help.

Sorry i was struck with imp release.

Now am back.

I tried what you said but it doesn't do anything, script just run and comeback.

Code:
admin@HP1 # cat script.sh
#!/usr/bin/bash

ufile=$1 #user file name
#ulf=$2 #user line from
ulf=25 #user line from
ult=30 #user line to

ifile=$4 #item file name
ilf=$5 #item line from
ilt=$6 #item line to

for user in `awk -vULF=$ulf -vULT=$ult 'NR>=ULF && NR<=ULT' $ufile` ; do
 for item in `awk -vILF=$ilf -vILT=$ilt 'NR>=ILF && NR<=ILT' $ifile` ; do
  echo $user @ $item
 done
done

I have both itemlsit and userlist file with 100 lines data in each

admin@HP1 # wc -l userlist itemlist
100 userlist
100 itemlist
200 total

Am i missing something here ?

My OS is :
uname -a
SunOS HP1 5.10 Generic_144489-09 i86pc i386 i86pc

Please let me know

hobbitcgi.cfg - Command-line parameters for the Xymon CGI tools SYNOPSIS
$BBHOME/etc/hobbitcgi.cfg DESCRIPTION
hobbitcgi.cfg(1) controls the commandline options passed to all of the Xymon CGI tools through their respective shell-script wrappers. Typ- ically the options listed here are used for system-wide configuration of the CGI utilities, e.g. to define where they read configuration files. The exact set of commandline options available are described in the man-page for each of the CGI utilities. The file is "sourced" into the shell script wrapper, so assignments to the CGI-specific variables must follow standard shell-script syntax. SETTINGS

This uses the bb-csvinfo.cgi(1) utility with the server/etc/columndoc.cfg configu- ration file. CGI_HOBBITCONFREPORT_OPTS Options for the hobbit-confreport.cgi(1) utility. CGI_HOBBITGRAPH_OPTS Options for the hobbitgraph.cgi(1) utility. CGI_HOSTGRAPHS_OPTS Options for the hobbit-hostgraphs.cgi(1) utility. CGI_NKEDIT_OPTS Options for the hobbit-nkedit.cgi(1) utility.
