Thanks a lot man! Fantastic! It worked! Could you kindly explain the code? I'm ignorant And also I just wanted how I can change array elements using sed within a loop. May be like this-
Code:
myarr=($(awk 'NR % 2 ==1' TestMe | awk '{print $2}'))
echo ${myarr[@]}
counter=1230;
len=${#myarr[*]}
for i in {1..len}
do sed "s/${myarr[@]} /$counter/g" TestMe;
counter=$(($counter+1));
done
Thanks a lot! Really appreciate it!

Reason: Just adding some lines
set -A arr a1 a2 a3 a4

ssh -xq $Server1 -l $Username /usr/bin/ksh <<-EOS
integer j=0
for loop in ${arr}
do
printf "array - ${arr}\n"
(( j = j + 1 ))
j=`expr j+1`
done
EOS

I want to run an awk split on a value that has been pushed through an array and I was wondering what the syntax should be??

I have a array as
CArray=( a1 a2 )
and a1,a2,a3 are also array as:
a1=(1 2 3)

now I have this in my code:
for i in `echo "${CArray}"`
do
echo ${$i}
done
It is giving error as :"bad substitution"
It should give me value as

Vend::CounterFile(3pm) User Contributed Perl Documentation Vend::CounterFile(3pm)NAME
Vend::CounterFile - Persistent counter class
SYNOPSIS
use Vend::CounterFile;
$c = new Vend::CounterFile "COUNTER", "aa00";
$id = $c->inc;
open(F, ">F$id");
DESCRIPTION
(This module is modified from Gisle Aas File::CounterFile to use
Interchange's locking protocols -- lack of fcntl locking was causing
counter problems.)
This module implements a persistent counter class. Each counter is represented by a separate file in the file system. File locking is
applied, so multiple processes might try to access the same counters at the same time without risk of counter destruction.
You give the file name as the first parameter to the object constructor ("new"). The file is created if it does not exist.
If the file name does not start with "/" or ".", then it is interpreted as a file relative to $Vend::CounterFile::DEFAULT_DIR. The default
value for this variable is initialized from the environment variable "TMPDIR", or /usr/tmp is no environment variable is defined. You may
want to assign a different value to this variable before creating counters.
If you pass a second parameter to the constructor, that sets the initial value for a new counter. This parameter only takes effect when
the file is created (i.e. it does not exist before the call).
When you call the "inc()" method, you increment the counter value by one. When you call "dec()" the counter value is decrementd. In both
cases the new value is returned. The "dec()" method only works for numerical counters (digits only).
You can peek at the value of the counter (without incrementing it) by using the "value()" method.
The counter can be locked and unlocked with the "lock()" and "unlock()" methods. Incrementing and value retrieval is faster when the
counter is locked, because we do not have to update the counter file all the time. You can query whether the counter is locked with the
"locked()" method.
There is also an operator overloading interface to the Vend::CounterFile object. This means that you might use the "++" operator for
incrementing the counter, "--" operator for decrementing and you can interpolate counters diretly into strings.
BUGS
(This problem alleviated by this modified module)
It uses flock(2) to lock the counter file. This does not work on all systems. Perhaps we should use the File::Lock module?
