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

NAME

       script - make record of a terminal session

SYNOPSIS

       script [-a] [filename]

DESCRIPTION

       The  script  utility  makes a record of everything printed on your screen. The record is written to filename. If no file name is given, the
       record is saved in the file typescript. See WARNINGS.

       The script command forks and creates a sub-shell, according to the value of $SHELL, and records the text from this session. The script ends
       when the forked shell exits or when Control-d is typed.

OPTIONS

       The following option is supported:

       -a	Appends the session record to filename, rather than overwriting it.

NOTES

       script places everything that appears on the screen in filename, including prompts.

WARNINGS

       script  can  pose  a  security risk when used in directories that are writable by other users (for example, /tmp), especially when run by a
       privileged user, that is, root. Be sure that typescript is not a link before running script.
