Bash script to read a file from particular line till required line and process
Hi All,

Am trying to write wrapper shell/bash script on a utility tool for which i need to pass 2 files as arugment to execute utility tool.

Wraper script am trying is to do with above metion 2 files.

utility tool accepts :
a. userinfo file : which contains username
b. item file : which contains items to be processed by mentioned users from userinfo file.

Below script works fine for userfile and itemfile

Am thinking of writing a wrapper script which call this script but in the wapper script it should execute utility tool from specified lines to perticular line from userfile and even for itemfile.

for ex : say userfile has 100 users and itemfile has 1000 items. so, i should call the wrapper script with passing argument saying run script for users from line 20-45 from userfile and say item from line 250-400 from itemfile.

basically it should run the utility tool from specified user number to a specfied item numbers.

Code:
#!/bin/bash

#echo "***********************************************"

count=1
userFile=$1

if [ -f $userFile ]; then
 echo "userfile exist"
else
 echo "user file $userFile do not exit, exiting !!!"
 exit 1
fi

for user in ` cat $userFile ` ; do
./dmstool -S rms -h 10.212.45.67 -f /tmp/itemfile -m -u $user
   #sleep 5
    echo "Completed - user $count"
   (( count=$count+1 ))
done

Any help will be much appreciated.

Thanks

installsieve

INSTALLSIEVE(1) 					      General Commands Manual						   INSTALLSIEVE(1)

 *

NAME

       installsieve - user utility for managing sieve scripts

SYNOPSIS

       installsieve

DESCRIPTION

       installsieve is a utility that allows users to manage their sieve scripts kept on the server.

OPTIONS

       -v <name> View script with the given name. The script if retrieved sucessfully is output to standard output.

       -l  List  all  of  the scripts currently on the server. If one of the scripts is active a arrow is printed indicating that it is the active
       script.

       -p <port> Port to connect to. If left off this defaults to "sieve" as defined in /etc/services.

       -i <file> Install a file onto the server. If a script with the same name already exists on the server it is overwritten.  Upon  sucessfully
       putting	the  script on the server the script is set active. If <file> has the extension .script it is chopped when put on the server since
       sieve names may not contain a '.'.

       -a <name> Set <name> as the active script. The list of available names can be obtained from the '-l' option..

       -d <name> Delete the sieve script on the server with <name>.

       -m <mechanism> Force installsieve to use <mechanism> for authentication. If not specified the strongest authentication mechanism is chosen.

       -g <name> Get the sieve script with <name> and save it to disk with a ".script" extension. If a file with that name already  exists  it	is
       overwritten.

       -u <user> Userid/Authname to use for authentication; by default, the current user.
