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
