hi

i need to write a script,

the script display's list of volume groups followed by physical volumes with in volume group and at the same time the script should display the pvid of physical volume.

what i need is, how to read the line by line from the files...

the below is my script..

echo "List of Volume Groups and Physical Volume:"
while read xxxxxx (the xxxx should read from file reportvg.out)
do
lsvg -p xxxxxx > reportpv.out (the xxxxx is vg anme)
while read xxxxxx ( the xxxx is the pv name from reportpv.out)
do
lspv xxxxx | grep IDENTIFIER ( the xxxx is pv name)

NAME

       lvmpvg - LVM physical volume group information file

SYNOPSIS

DESCRIPTION

       is  an  ASCII file that stores the volume-group information for all of the physical volume groups in the system.  The information is stored
       in a hierarchical format.

       First, it starts with a volume group under which multiple physical volume groups can exist.  Under each physical volume group,  a  list	of
       physical  volumes  can be specified.  There must be at least one physical volume group in each volume group that appears in this file.  The
       physical-volume-group name must be unique within the corresponding volume group, although it is permissible to use a common physical volume
       group name across different volume groups.  There can be as many volume groups in this file as there are in the system.

       Instead of using the and commands, the administrator can edit this file to create and extend physical volume groups.  However, care must be
       taken to ensure that all physical volumes to be included in the file have already been defined in their respective volume groups by  previ-
       ous use of or

       The  file  format  has  the  following structure.  and are keywords that introduce the names of the volume group and physical volume group,
       respectively.

	      pv_path
		 ...
	      pv_path
		 ...
	      pv_path
		 ...

       The variables are defined as follows:

	      pv_path	     The block device path name of a physical volume within the volume group.

	      pvg_name	     The name of the physical volume group.  It must be unique within the volume group.

	      vg_name	     The path name of the volume group.

EXAMPLES

       The following example shows an file containing two volume groups: the first containing two physical volume groups, each with  two  physical
       volumes defined in it; the second containing three physical volume groups, each with one physical volume defined in it.
