A different approach (actually, two!)

Here is the new script

Code:

> cat alpha1
#! /bin/bash

#remove old files
rm count.txt 2>/dev/null
rm p1vma* 2>/dev/null

#set the variable
NUMBER=13
CURRENT=0
while [ $CURRENT -le $NUMBER ]
   do
      if [ $CURRENT -gt 1 ]
         then
#         printf "%.2d \n" $CURRENT
         printf "%.2d \n" $CURRENT >>count.txt
         lv_val=$(printf "%.2d" $CURRENT)
#do lv stuff here
         touch p1vma$lv_val
      fi
      CURRENT=$(($CURRENT + 1))
done

#see the files just created
ls -l p1vma*

It creates the count.txt file, although not sure if truly needed...

Code:

> cat count.txt
02 
03 
04 
05 
06 
07 
08 
09 
10 
11 
12 
13

because, you can do you lv stuff while inside the loop. In this case, I touch'ed files to create/put timestamp. See the following as output from execution

Code:

> alpha1
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma02
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma03
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma04
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma05
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma06
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma07
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma08
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma09
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma10
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma11
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma12
-rw-rw---- 1 jgillis dp 0 Feb 26 11:08 p1vma13

       the  command  source  with the Tty parameter. Output is then restricted to the specified parameters. A Tty terminal may be named fully (for
       example, tty0) or abbreviated (for example, 0).

       The following information is displayed for each process: Name of the command under which the process was called.  Any flags collected  when
       the  command  was  executed.  The following flags are valid: Command was run with an effective user-id of 0.  Command ran after a fork, but
       without an exec system call following it.  Name of the user who issued the command.  The terminal the command was started from.	Seconds of
       CPU time used.  Time the process started.
